Let’s talk about the 4 main types of slurry pumps!

 All the many pumps in this industry have their own different types. This is true in case of pumps like slurry, sewage, dewatering, etc. Therefore, when choosing a pump you should go for a provider who can offer you a wide range of pumps. This will make sure that you are being given all the options that exist out there.

At the same time, it is important to know about the pumps, before choosing them. This blog is going to focus on the 4 main types of slurry pumps. 

A slurry pump is a kind of centrifugal pump. A slurry pump refers to machinery that increases the energy of solid-liquid mixed medium with the help of the centrifugal force. The centrifugal force is nothing but the rotation of the pump’s impeller. The pump converts the electric energy into the kinetic energy as well as the potential energy of the medium.

In today’s market, you will be able to find many types as well as models of slurry pumps. These different types of slurry pumps get majorly used in order to execute slurry transportation when it comes to metallurgical concentrators, coal slurry and heavy medium transportation in coal washing plants, hydraulic ash removal in thermal power plants, river dredging, slurry lifting in sand washing plants and many more applications.

Main types of a slurry pump:

Horizontal Slurry Pump

In a situation where you find the position of the slurry pump shaft to be parallel to the horizontal plane, it is referred to as a horizontal slurry pump. This pump is a single-stage, single-suction, axial suction cantilever horizontal centrifugal pump. It comes with high-strength as well as wear-resistant materials for the over-flow parts. Based on the different suction media, the given filter components of different materials can be exchanged with each other.

Vertical Slurry Pump/Cantilever pumps

In a situation where the position of the slurry pump shaft is perpendicular to the horizontal plane, it is referred to as a vertical slurry pump. Generally, this pump is used in the slurry pool for pumping the slurry. In this case, the pump head should be placed below the liquid level. Then, it would be called the submerged slurry pump. A thing to remember here is that not the whole pumps are submerged into the water. 

Submerged Slurry Pump

This one is a vertical single-stage, single-suction cantilever centrifugal pump. The impeller of this pump is a semi-open impeller. The mixing blade is arranged at the impeller’s suction edge extension.

The length of the pump shaft in the submerged part is around 800-2000mm. There is no bearing to be found between the impeller as well as the pump shell. The driving unit of the pump is installed on the motor support as well as the support seat by the vertical motor. The coupling gets used for connecting with the pump.

Submersible Slurry Pump

This Pump is the coaxial integration of the pump as well as the motor. Here, the motor submerges into the slurry. In this case, there is no need for building any kind of complex fixtures or protective measures on the ground. The motor gets protected by mechanical seal. This can prevent impurities as well as high-pressure water from entering the motor cavity. Here the stirring impeller touches the deposition surface directly. The slurry concentration gets controlled by the diving depth. Lastly, the slurry automatically pours into the pump in order to save a good amount of energy.

Now that you have an idea about the types of slurry pumps, you would know that there is so much to know about any given pump. Therefore be it sewage pumps, dewatering pumps, or any other pumps, if you’re planning to choose one, go ahead and dig deep into what it does, how it works and more of the same kind of information.

What really matters when choosing a slurry pump?

Choosing the correct slurry pump for an application is a tedious job. When it comes to slurry pumps, they are the pumps that can be found in many industries. They play an imperative role in various processes. In this blog, you will find the 3 key aspects, that one should look for in deciding the proper slurry pump. These include the design of the slurry pump, the slurry pump deployment, and the pump construction material.

1. The Design of a Slurry Pump

When you think about the design of a slurry pumps, it is important to consider the abrasive as well as corrosive aspects of the given slurry, as  this may lead in high wear out pattern in rotating parts coming in contact of said slurry. On top of this, it is possible that the sludge and slurry might contain large and unforeseen solids. These will inevitably clog various types of pumps. It is a fact that most of the centrifugal pumps have an impeller with close tolerance to the volute, and this is why the abrasive and sometimes corrosive nature of the slurry results in the quick wearing of the volute and ruining of the tolerance. This results in the pump losing its suction capability. Ultimately, this causes massive downtime with slurry pumps. It also comes along with costly spare parts as well as maintenance.

This is why it is imperative to think about the design of the slurry pump before making the decision to buy it! 

2. The Construction Material of the slurry pump

When it comes to the material of the pump, choosing the proper one for a slurry pump is another very critical process, in order to determine the correct pump for handling your slurry. If in case the slurry is highly abrasive and has a neutral pH, then the best choice of the construction material will be a Hi-Chrome. This specialty of this metallurgy is that it has the highest Brinell hardness, which can withstand the abrasive nature of the given slurry. On the other hand, when the slurry is abrasive and also has a low pH, the best choice is to go with duplex stainless steel construction. This is the material that is the best for a slurry pump for withstanding caustic material. This material is generally best suited for a slurry pump for withstanding caustic material.

3. The  deployment method of the slurry pump

In determining the ideal setup, an important step is to determine the ideal deployment of a slurry pump. There are around three main slurry pump deployment methods. These include submersible slurry pumps, self-priming pumps, as well as flooded suction pumps.

Studying these three options well, and then choosing according to your needs will help make the best decision of buying the right slurry pump. 

Apart from these three key aspects, there are some more. These include the slurry pump seal and the slurry pump power sizing etc. So, before buying a slurry pump, make sure to keep these aspects in your mind, and only then make a decision.

Got A Problem With Your Submersible Pump?

Are you currently using submersible pumps? And are you facing problems with it? Are these problems recurring? Have you found a solution to it? Well, don’t get worried just yet. We’re here to help you. As experts of an industry that deals with pumps like high head submersible pumps, raw water pumps, etc., we understand all kinds of problems that one might face.

Therefore, in this blog, we are going to help you out by discussing the problems that are related to a submersible pump. Here, we are going to be focusing on one of the most common problems that a submersible pump faces, the possible reasons behind it, how you can check it, and finally, how you can correct it! So, let’s get started:

One of the most common problems- When your submersible pump isn't starting!

Possible Reason One- It is possible that power is not being supplied to the submersible pump.

Check- Try placing a voltmeter across the power lines that are coming into the submersible pump. In this way, you will be able to check the power supply for the overload protection box.

Correct- If you find that there is no power to the box, then the power company should be consulted.

Possible Reason Two- It is possible that there is no overload protection.

Check- Try examining the circuit breaker as well as the fuses to the submersible pump for ensuring that they are being operated correctly.

Correct- If you find that the breaker has been tripped, then replace the blown fuses and reset it.

Possible Reason Three- It is possible that the pressure switch on the submersible pump is damaged.

Check- Try checking the voltage across the switch, keeping in mind that the submersible pump pressure switch is in a closed position. If you find that the voltage drop is at the same level as compared to the line voltage, then it is obvious that the switch isn’t making contact.

Correct- In such a case, the contact points should be cleaned. Also, the pressure switch should be replaced for the given submersible pump. 

Just like this, there are more problems that a submersible pump faces. Sometimes, a submersible pump will not stop running, sometimes it starts up too much, and sometimes it works but would deliver little or no water.

Knowing a Sewage Pump!

Are you curious about pumps like submersible sewage pumps, dewatering pumps, raw water pumps, etc? Well, that’s a good thing to be! And you’ve landed at the right place to satisfy that curiosity. 

In this blog, we are going to be sharing about sewage pumps in particular. We will be covering the basic topics like what are sewage pumps, types of sewage pumps, benefits of sewage pumps as well as the maintenance and repairs that this device comes along with. 

Let’s get started with the very basic question; What are sewage pumps? 

This pump is used for transferring sewage liquids as well as solids from one place to another. In general cases, with residential applications, the sewage includes soft solids that go up to 2″ in diameter. It is pumped from a sewage basin to a septic tank or a sewer system. When it comes to a sewage pump, you should know that it is installed at the lowest point of the given sewage basin.

As the submersible sewage pump is submerged almost all the time, it gets this name. These pumps can be manual, automatic, or even dual mode. 

Let’s move on to the types of sewage pumps that are out there:

1. Effluent Pumps – These are the pumps that in most often cases, are used in a small on-site system.  Designed to pump effluent, they have the effluent flowing out of a septic tank. 

2. Solids Handling Pumps – Also called sewage ejector pumps, they are made to pump raw sewage. 

3. Grinder Pumps – Much like a solid-handling pump, this one can also pump raw sewage. The difference is that this pump comes with rotating blades, just like garbage grinders. Before the sewage has pumped, these blades cut as well as grind the solids into small particles.

Now, let’s talk about maintenance and repairs: 

1. Make sure that the ground fault circuit interrupter is working, if installed. 

2. When removing the cover, remember that there are 3 common types of lids with different removal methods.

3. Conduct an inspection of the pit for debris or silt. 

4.  Make sure to check the drain line from the pump until it meets the air gap and look for any signs that indicate holes, corrosion, leaks or damages.

When you think about the maintenance and repair tips, there can be many more. However, these should get you started! Keep researching and learning new things about your pumps to make better decisions as well as executions!  

Your Guide to Sewage Treatment Plants!

When you’re inclined towards knowing about sewage pumps, you should dig deeper and get to know about sewage treatment plants as well. If it had to be said in simple terms, a sewage treatment plant refers to a below-ground vessel that helps in treating the incoming effluent to a quality that is environmentally acceptable. Further, the given treated water can be legally discharged in ground soak away following applicable consents or exemptions or to flowing surface waters.

How do sewage treatment plants work?

Almost all the sewage treatment plants are known to use the same 3 stage principle in order to treat the influent; primary settlement then biological treatment and then final settlement.Have a look at these stages:

Stage 1 – At this stage, the influent enters the primary settlement chamber. This is where the solids sink to the bottom of the chamber. Here, they begin to form a sludge. This sludge is periodically removed with the help of a tanker.

Stage 2 – At this stage, the remaining liquid would move forward to the biological treatment zone. Now, this biozone is where the air containing oxygen is introduced to the liquid. This is done for encouraging the growth of aerobic bacteria. These bacteria are found naturally in the sewage. It is done by allowing the bacteria to breath. In most treatment plants, the use of media in the biozone is also seen. This helps in providing a huge surface area for the same bacteria, for it to cling to as well as grow.

Stage 3 – Finally, at the third stage, the treated effluent starts moving into the final settlement chamber. This is where the calm will allow the biological material to settle. In such cases, it settles at the bottom for further treatment or periodic removal. Eventually, the remaining settled liquid will start flowing out to the surface waters or the ground soak away.

How to install them?

The user of sewage pumps would always know the importance of a complete range of sewage treatment plants that accommodate the needs as well as wants of a very diverse range of applications or properties. 

Great providers can help you size and find the most cost effective as well as compliant solution. You should make sure to go to installers and merchants, who are the experts in the industry and have the capability to serve your requirements. This will lead to a successful and smooth installation.

Touching The Basics Of Water Pumps

Whether you wonder about high head submersible pumps, or want to know more about dewatering pumps, or are simply curious about raw water pumps, you need to know the basics of any water pump.

Many times, even knowing the basics doesn’t cut it as it is imperative to actually remember them. So, whether you are a person who is totally unaware of the basics of a water pump, or a person who has simply forgotten about some of them, this blog will benefit you. 

HOW DO WATER PUMPS WORK?

The pumps function through creating a vacuum. In this vacuum, the ambient air pressure does the job of forcing the liquid. It is imperative to know that all the pumps work by creating low-pressure areas. In a centrifugal pump, centrifugal force accelerates the water to the outside of the impeller creating low pressure at the center or the eye of the impeller. When it comes to reciprocating pumps, the upstroke of the plunger or piston plays the role of creating a vacuum. On the other hand, when it comes to in-gear pumps or lobe pumps when the teeth or the lobes mesh and then come apart, the creation of a vacuum takes place. It is the difference in the pressure that leads to creating a suction. As a fact, we know that a liquid under higher pressure moves to an area of lower pressure.

LET’S TALK A LITTLE ABOUT PUMP PERFORMANCES

One thing to know about pumps is that they have strict tolerances as well as precise conditions.  They must operate under these conditions in order to generate the BEP or what’s known as the Best Efficiency Point. Each and every pump possesses a chart that shows the performance curves. They also display how the attainment of the BEP can be achieved. Whether they make high head submersible pumps, dewatering pumps, or any other pump, all manufacturers go for calculating the performance curves with the help of a pressure gauge as well as a flow meter. This is connected to the discharge port in order to find out the optimal configurations of piping, type of head and fluid, etc. It is fortunate that the discharge capacity is possible to be calculated for any head.

SHEDDING LIGHT ON THE BASIC PARTS OF PUMPS

The basics include the casing, fluid displacement device, bearings, the hub, as well as the Seal. 

Apart from these basics, there’s much more to know about pumps.

How To Rightly Choose a Water Pump That Suits Your Needs?

In simple terms, a water pump refers to a mechanical device that does the job of transporting media. This is done by transforming the energy that is being supplied by a motor, into hydraulic energy. When it comes to choosing the right water pump, be it sewage pumps, or dewatering pumps, or any other kind of pumps, there are some things that should be carefully considered. 

So, when we look at the first criterion for choosing any water pump, it becomes the type of media that is concerned. The right thing to do is to take into account the technical characteristics of the media. It is because they are the ones that will determine the choice to be made.

Further, to properly dimension the machine as well as to calculate the operating point of the water pump, it is important to know the parameters of the network. They include flow rate, static head, frictional losses, total working head, contamination (solids) in media and more like it.

This blog helps in giving you an overview of a few main types of pumps as well as the situations in which they are generally used.      

Firstly, one needs to determine what media is going to be transferred, this is for avoiding corrosion phenomena and by that also avoiding premature wear of the pump. Therefore, it is highly essential to know the chemical composition of the media that is to be pumped. One needs to determine if the media is chemically neutral or corrosive, this aids in choosing materials that will be compatible with the pumped media

Secondly, one should know the possible presence of solid components, and the viscosity of the media. Knowledge about all the physical properties of the treated fluid allows choosing of ideal technology for given application as well as the ensuring that pump operates trouble free under given conditions.

Remember a general rule, that the more viscous the media at hand, the tougher the flow through the pumping system. However, be careful as the viscosity varies according to different operating conditions.

Thirdly, there are different types of pumps out there. They are:

• Centrifugal pumps; where the fluid gets sucked by a paddle wheel/ propeller (most common model).
• Diaphragm pumps; where the fluid is sucked in through the oscillation of a diaphragm.
• Piston pumps where the fluid is sucked in as well as out by one or more pistons’ reciprocating movement.
• Peristaltic pumps; where the fluid gets pushed into a pipe that is compressed by rotating rollers.
• Submersible sewage pumps; where the fluid is pumped by submerging the motor under the liquid.

So, when choosing sewage pumps, or any other pumps like dewatering pumps, make sure to consider these three points before making the final decision.

Did You Know This About Mine Dewatering Pumps?

When it comes to any kind of pumps, be it dewatering pumps, sewage pumps, or any other kind, it is always best to know what you’re getting into. In this blog, we will be talking about mine dewatering pumps.

For starters, let’s have a look at what is mine dewatering.

Understanding the process:
In the simplest terms, the process of mine dewatering refers to the act of taking out groundwater from a mine.

Types of mines:
There are various types of mines like coal mines, iron ore mines, etc. But, why is it important for you to know about them? Well, when considering executing the process of mine dewatering, you will need to know about the abrasion of the given liquid to be pumped out. Depending on the mine, the abrasion of the liquid will also vary. Many of your mine dewatering decisions will be based on this consideration.

Pumping challenges faced during mine dewatering:

1. The difference in mines- When we look at different mines, we see how there are two types. One is the close mines, and another is the open mines. The challenge is that for both the mines, there are different safety parameters. According to this, you will have to choose the dewatering pumps that suit your needs.

2. The difference in voltage requirements- Depending on safety parameter voltage requirements are different for different mine sites. Therefore, when it comes to mine dewatering, you have to ensure that the dewatering pumps you chose are compatible to work with given voltage range.

3. The difference in head requirements- Usually, the head of the pumps need to be higher for the successful execution of mine dewatering. Therefore, it’s very important to go for pumps that have proven track record in such typical process.

4. Wear & tear of critical parts- This is the most critical aspect of mines dewatering. If metallurgy of your mines dewatering pumps is not compatible for pumping abrasive liquids, then your mines dewatering pump can become a huge liability & kill the project cost altogether.

How can submersible pumps be useful?
Generally, different types of pumps are deployed for mines dewatering purpose, many a times these are huge horizontal surface mounted pumps. These pumps may have its own benefits but, they may not serve the above stated purpose perfectly.  However, in modern times submersible mines dewatering pumps are evolving as a big boon for mines dewatering. These pumps are not only lightweight & portable, but also come in various sizes & capacities to suit given site conditions. Based on your requirements you can Mix-n-match the ratings / capacities to make these submersible mines dewatering pumps to reach even remote locations of your mines.

The good submersible mines dewatering pumps manufacturer offers variety of options in terms of metallurgy which is suitable for various abrasive liquids to be pumped & their modular design not only aids in interchangeability of spares but also bring down the overall spare’s consumption for users. So, buying a mines dewatering pumps might appear to be an easy thing, but actually a right mines dewatering pumps can make your life easy.

Maintaining Your Submersible Sewage Pumps

When it comes to pumps like submersible sewage pumps, everyone wants to just do their best to maintain them! However, lack of proper source of knowledge usually gets them at a place where it’s tough to execute it. Therefore, this blog has been created in order to help such wishers, to succeed with proper information and ease.

The submersible sewage pumps are the kind of pumps that are connected with the pump and their motor is submerged under the liquid. They are suitable for various occasions. For making the equipment last longer, one needs to know about the submersible sewage pumps’ techniques of maintenance.

Few of the critical aspects which needs to be looked into:

1. Determining the correct direction of the motor’s rotation:
In case of Submersible Sewage Pumps, direction of rotation of pumps is one important aspect. These days it is generally observed that lack of awareness in these aspects often leads to abnormal working of pump. It is important to ensure that pump is running in right direction, or else it can adversely affect its flow & current consumption often resulting in damage in winding.   

2. Preventing the power supply voltage from an abnormal start:
It is a known fact that the low-voltage power supply line is relatively long. Due to this, the end voltage of the line being too low becomes a common occurrence. In a case where the phase voltage is lower than normal the speed of the motor of the given submersible sewage pump goes down drastically. This results in abnormal heat up of motor or even burning of an winding.

3. Device for leakage maintenance:
A life-saving device helps with leakage maintenance of the submersible sewage pumps. As pump operates underwater, a simple leakage can lead to power loss and could even end up in an electric shock. If this device is installed, it will block the power supply of the submersible pump ensuring safety and preventing leakage when required.

The other things that one should consider are preventing frequent Start & Stops, not letting the submersible sewage pump work in overload condition for a long time, paying attention to normal maintenance by usually checking the motor current, etc. 

Follow these simple techniques and you’ll be good to go!

Basic Pump Facts That One Should Know

Whether it is about raw water pumps or any other pump, one can only be confident about operating them when he or she knows the basic facts about water pumps. Therefore, it is always a better idea to at least skim through these basic facts. For the convenience of those curious ones out there, we have curated a list of such facts in this blog. 

 

Please have a look at the following:

Water pumps don’t suck fluids:

In the world of pumps, this is a very common misunderstanding. People need to realize that there is some energy source other than the water pump itself, that should supply the energy that is required for the fluid to get to the water pump. This is simply because water pumps do not suck fluids. In normal cases, these sources can be atmospheric pressure and/or gravity. In the end, one needs to remember that the fluids don’t have tensile strength. This is the reason why water pumps do not have the capability of reaching out and pulling fluid into the suction.

The realistic suction lift is around 26 feet (maximum):
It’s already been stated in the previous fact, water pumps do not suck fluids. Now, if you’re at sea level, then the atmospheric pressure would be 14.7 pound per square inch absolute (psia).  This simply translates (multiply by 2.31) into around 33.9 feet of absolute head. One might have been able to lift cold water 33 feet if there was no vapor pressure or fluid friction working against the entire system. Unfortunately, in reality, the fluid friction, as well as the negative consequences of vapor pressure, would end up working against you and precluding the fluid lifts of much more than 26 feet.

Almost all of the pump’s problems take place on the suction side:
Unfortunately, there is another very common as well as a pervasive misunderstanding about the working of water pumps. When you imagine any pump system acting as three separate systems, you’ll be able to understand better. Now, imagine them troubleshooting issues out in the field. The pump, the suction system, as well as the system downstream of the pump all working together. Studies show that around 85 percent of the pump issues always occur on the suction side of the pump. Therefore, whenever you are in doubt, its always a great idea to start looking at the suction side for the solution.

Are you New to Pumping Slurry?

If you are one of those who has ever pumped slurry, you would be able to tell and know it in your heart, that it has the capability of being one of the most challenging fluids to be moved. The slurry is a fluid that is abrasive, sometimes corrosive, thick, and it is also known to contain huge amounts of solids within. There is no doubt about the fact that slurry is a fluid that is tough on the slurry pumps. 

 

However, if you have a good amount of experience in using slurry pumps, you would also realize that the more you understand about what is going to be pumped, the better your water pump selection is going to be in every case. This decision will help you in decreasing the failures while pumping slurry.
To understand anything further than this, one should have a basic idea of what is slurry.

So, the question is, what is slurry?

Slurry refers to any mixture of fluid, such as water, combined with a pulverized solid. Slurries are known to be used as a convenient way for handling solids in bulk. This can be in mining, foundries, steel processing, and power generation. Generally, slurries tend to behave the same way as vicious as well as thick fluids, that flow under gravity behave.

So, one should be aware that slurries can be divided into two general categories. These are settling and non-settling. The non-settling slurries have very fine particles. They give the illusion of increased apparent viscosity. They have low wearing properties but need careful consideration when selecting the pump. This is because they don’t behave like a normal liquid does.

The settling slurries get formed due to coarse particles. These tend to form an unstable mixture. The flow and power calculations need attention while a pump is being selected. Mostly all slurry applications are made of coarse particles. This is why they have higher wear properties.

There is another very important thing that should be kept in mind. In order to understand slurry pumping, one has to go to certain depths. Not only do you need to be aware of the basics like mentioned above, but you also need to know all about pump selection considerations. 

Even after knowing it all, you need to put it into application. Only after gaining a good amount of experience with slurry pumps, you will be able to practice it successfully.

Talking about Sewage and Sump Pumps!

Imagine someone who has just rebuilt his/her home and is now facing something that looked like a very simple change caused due to a sewage pumps installation in his/her basement. He/she had probably done it for directing all of the basement’s sanitary waste into the main sanitary drain. Now imagine that unfortunately the builder had made a big mistake and decided to install the new concrete slab a little lower than the level of the existing old floor. As you must have guessed by now, it would have resulted in having to lower all the drains in the basement.

Only when this job would be completed, it would be possible to install any of the sewage pumps.

However, after about a month and once every month post this incidence the pump would constantly break down. Nevertheless, you should understand that the Issue would have nothing to do with the pump installed. The issue was more about what was being sent into the given sewage tank.

Something to learn here is that usually, in residential applications, the sewage gets pumped from a sewage basin or to a sewer system or even to a septic tank sometimes. Sewage pumps should always be installed at the lowest point of the given sewage basin. Also, the basin in itself should be placed below or at the floor level of the particular basement.

Another important question to be addressed is ‘how long will sewage pumps last?’. Well, that depends on various factors. One of the important factors is how often and how long the sewage pump is running for & in what conditions. It is natural that pump most suited for given condition will  last as long compared to pump in other conditions.

Therefore, it is very important to know about sewage submersible pumps, before using them. 

Now that we’ve talked a little about sewage pumps, let’s talk about sump pumps.  

When it comes to sump pumps, flooding becomes the number one reason for its requirement in a house. So, when we talk about homes that have water issues in the basement, we also acknowledge the problems beyond water like rot, mold, rust and even unhealthy air to breathe. This is when the use of sump pumps becomes absolutely necessary. 

There are many other things that one needs to know about sewage pumps as well as sump pumps. However, this blog gives a small idea about both of them.

Here’s what you didn’t know about the Dewatering Process!

The dewatering pumps are used for various purposes. Therefore, it is important to know as much as you can about the dewatering process. This is why this blog is going to tell you a few interesting facts, that you probably didn’t know already.

Here goes:

1.Excess water acts as a problem in and out of the site

Firstly, one should know and believe that the dewatering process is quite simple. It is as simple as work being done, water being accumulated, and further, water being extracted. However, there is something that does make the practice complicated. This is what comes right after the step of extraction. Most of the companies out there face issues related to where the water acquired is to be dumped. This has become a very common issue with all such companies that are using water pumps. This is because the pipes directly go for directing the water into an underground system. Now, the issue is that if it’s placed at a place which is somewhere nearby, then it causes the soil to erode. This could easily affect the construction at a point later on.

Therefore, the common practice is to first test out the dewatering plan and then see the effects of the water on the release area.

2.The techniques of dewatering are quite simple

We all know that dewatering is just taking away water and further moving it to some other place. However, there are different techniques that various companies are trying to use for the same. Out of all of them, the most common one is by the use of pumps like dewatering pumps. Some go on creating deep wells as well as drains for keeping the water level to the minimum. On the other hand, some companies are using siphoning techniques. The simplest dewatering way is by scooping out the water with the help of heavy machinery. It is then placed in a container, further transported to the area that it is going to be directed to. This works best when the water levels are still low.

There are many other interesting facts about dewatering pumps and its techniques, that you can find out by digging deeper. You would go on to find that it is a long process which takes months or weeks to complete. Also, that dewatering is important for quick as well as safe completion of projects that are large-scale.

Talking About Ash Slurry!

As long-time manufacturers of slurry pumps, Darling Pumps realizes that the topic of ash slurry is a little complex. However, whether we talk about slurry pumps, or submersible dewatering pumps or any water pumps for that matter, no function of them is impossible to understand.

Therefore, in an attempt to help the people who are feeling a little lost when it comes to the subject of ash slurry, this blog explains a little about the same.

For starters, you should understand that in thermal plants, coal is used as fuel in order to generate electricity. Burning of coal leads to the generation of ash. This generated ash needs to be carefully disposed off from the thermal power plant.

Following are the types of ash generated in a thermal power plant:

1. Fly Ash- Out of the total of ash generated in thermal power plants, around 80% is fly ash. This ash is in the form of really fine particles. 

2. Bottom Ash- This refers to the ash that is being generated below the furnace of the thermal power plant. The bottom ash is about 20% of the total ash generated. Due to its coarse nature, bottom ash needs to be further crushed before it can go into the ash handling system.  

If you lost us at ‘the ash handling system’ then don’t worry, here’s a little bit which explains to you, what that refers to. 

The ash handling system is also known as the ash handling plant. This is used in thermal power plants to cool down the generated ash and bring it down to a manageable temperature.  Further, it is transferred to a storage facility or a disposal area and used in other industries.

The ash from the bottom ash handling system, when mixed with water in bottom ash silo, forms slurry. This new formed slurry is then transported to ash disposal area. From here the slurry is further pump out through slurry handling pump.

Although in doing this slurry pumps suffer through a lot of wear and tear. This wear and tear lead to its own set of problems, like the following:

1. Increase in maintenance and repair costs

2. Improper quality of pumping 

3. Replacement costs 

4. More time to get the job done right

Therefore, one should always focus on getting the right kind of slurry pumps, when it comes to dealing with something as complex as ash slurry.

How Dewatering is seemingly simple, yet complex?

When people think about submersible dewatering pumps, some may say that the application is fairly easy. However, it may seem easy, but at times dewatering is a complex process. 

To be precise, each dewatering activity comes with its unique set of challenges For starters, the reliability of dewatering pumps is something that people keep looking for. But with full honesty, this is not something that every dewatering pump manufacturing company can provide for. 

Now, let’s look at the process a little more closely in order to understand the other challenges that it comes along with. 

When it comes to construction as well as mining projects, many time groundwater seepage proves to be a major obstacle. It presents itself as an obstacle to efficient, safe, as well as cost effective excavation. 

In simple terms, dewatering refers to the process of dealing with groundwater. This is done in order to allow excavations, for them to be carried out in workable and dry conditions. When the process is executed in a proper manner, and is done well, it becomes a seamless part of the excavation process as well as the construction activity it is undertaken for.

It becomes crucial that the process of dewatering is planned as well as implemented in an organized manner. This is so because when it is executed in a bad way, the process of dewatering would not dry out adequate groundwater. Neither would it be able to stabilize the long construction delay and cost overruns. In this way, it might even result in major project instability.

In the middle of reading this blog, you may stop to wonder, why the challenges of the process of dewatering are important for you to know. Well, this is because submersible dewatering pumps and other pumps that allow the execution of the dewatering process, can cause trouble if not handled well. All in all, dewatering is an imperative process.  

The process of dewatering is to get rid of excess ground water which in turn aids to carry out proposed activity seamlessly. This can include mining activity, Construction activity or for that matter a disposal of water. 

In conclusion, the process of dewatering seems to be easy, but can be quite challenging if you are at a lack of knowledge about the subject. Apart from this, one should make sure to only go for a trustworthy provider, when it comes to dewatering pumps. 

Happy Dewatering!

Why is your submersible pump failing?

In the world of pumping, you will often come across many manufacturers providing you a variety of pumps like submersible sewage pumps, dewatering pumps, etc. However, while telling you about themselves and their products, they hardly ever mention the possible cause of failure of their pumps.

In this blog, we are going to choose the path of honesty, and tell you all about the reasons of a submersible pump’s failure. Even though we are the proud manufacturers of many submersible pumps like submersible sewage pumps etc., we understand that this is something our customers should know.

Following is a list of reasons to a submersible pump’s failure:

1. Ignorance and wrong selection of the submersible pumps

Although this reason might sound tiny, but it is the most common reason for submersible pump failure.  Many a times customers have an ignorance towards pumps & are often ill advised in this regard. Eventually they end up buying wrong pumps. This may not only lead to wrong use of pump, but often affect the performance of the submersible pumps, eventually leading to its failure. 

Not only this, but many times people try to use a one pump for several different needs & without knowing it make pump useless all purposes. 

2. Dry running of the pump

This is 2nd most common reason for submersible pump failure. After selecting a right pump, it is also important to ensure that it is put to use for right purpose & is also equipped with basic control precautions. Taking these things for granted eventually leads to dry running of submersible pumps. What people don’t know is that the dry running of a submersible leads to heating up the motor of the pump. This causes it to fail.

3. Reverse rotation 

This failure is caused when a submersible pump is wired incorrectly. This means that the motor would run backwards. In case this happens, a very less amount of water gets pumped. Moreover, this seriously damages the pump. It also polishes the impeller which further leads to cavitation.

4. Cable Damage

This is another common reason for submersible pump failure. More often than not, cable is most ignored part of the pump. Mishandling of pump can cause internal or external damage to cable. If the cable has been yanked or gashed, then it should immediately be checked. One should always ensure that there is no undue stress on cable during it handling or fitment. The seal arrangement where the cable is entering the pump’s body, is a weak spot, even just a few drops of moisture can successfully lead to the pump’s failure.

Apart from these, there can be other reasons (which we will cover some other time) leading to a submersible pump’s failure.

However, keeping these above most common points in mind will help you make better decisions regarding pump selection & its usage. Contact Darling Pumps at +91 9981992833, or visit www.darlingpumps.in

Questions about water pumps? Get your answers here!

Whether you’re thinking about dewatering pumps, submersible waste water pumps, sewage pumps, or any other type of water pump, it’s natural that you would have many questions popping in your head, Well, if anything, that’s a good thing. However, it’s only healthy to get the answers to all these questions before the lack of knowledge gets you in trouble.

In an attempt to help you and many others like you, here’s a tiny list of those questions along with their answers: 

1.What do you mean by an open centrifugal pump?

These pumps use centrifugal force for pressurizing and moving water from inlet to outlet. The pump shaft spins the impellers. Water gets forced through the impeller and rotational energy gets transferred from the impeller to the water. 

2. Why is my pump making noises?

Mostly water pumps are fairly quiet while in operation, However, at times pumps may make noise due lose & faulty installations, improper pipe fittings or noise may even come from hydraulic portion of pump. Therefore, always ensure weather the noise is coming from the pump. If the pump makes a popping, growling, squealing, or grinding noise, then you should immediately get it attended by trained service technician who may have to disassemble it and inspect for damage. 

3. Why did my pump’s shaft break?

The shaft failures could be because of many factors. These include:

• Sudden & frequent starting or stopping the pump.
• When engaged suddenly, a water pump may twist the impeller off the shaft. This can end up damaging the shaft & bearings.
• Water hammer that is caused by a sudden shut off of water flow causes the impeller to break the pump shaft. Over time, it also damages the shaft bearings. It always advisable to have NRV fitted to pipeline.
• A damaged or unbalanced impeller may cause shaft failure as well as bearing damage.

4. When should the gaskets of the water pumps be replaced?

Whenever the water pump is partially or fully opened for servicing or for any other reason. Also if Gaskets are found to be damaged or cut they should be replaced. They are inexpensive, and a faulty gasket causes the water pump to leak.

We know there are lot more questions that we are been asked. And, we love to help-out the people who seek these answers.

What questions should be answered, before selecting sewage pumps?

When it comes to sewage pumps, everyone’s dream and necessity is to own a properly working one. This stands true especially for homeowners who have basement toilets. 

The role of sewage pumps is to lift flushable waste into a septic tank or the sewer line. There are many people who often go for replacing their water pump with the same model as before. Before making the decision, you should always ask yourself, how long should your pump last?

Similarly, when selecting the right sewage pumps for your needs, there are some questions that you should ask yourself! The following is a list of those questions, along with the answers to the same:

1. How much flow is required?

To know what type of flow rate is required, it’s important to know the number of users that would be feeding the sewage basin as well as the number of drains. If you want to know a great rule of thumb, then its 50 gallons per person per day for residential use.

2. What about the vertical lift’s distance?

If you are familiar with the pumping industry, then you would have questions like “what is the total dynamic head?”  and “what is the head?” or something in these lines. All of these questions are asked to help in determining the amount of force or pressure needed for “pushing” the liquid up to where it’s required to go. Considering whether the system lifts to a septic tank, in the absence of any back pressure or to a sewer system with pressure pushing back, is imperative.

3. What are the requirements when it comes to solids handling?

Such type of requirements might be easily determined by the local codes. A sewage pump should have the capacity to handle spherical solids that are up to 2” in diameter, unless otherwise stated.

4. What is the size of the pump basin required?

Normally, the flow rate determines the size of the basin that is needed. A properly sized basin allows the water pump to run for longer on each cycle. It would also help to cycle less times each day. Generally, the larger the motor, the less cycles each day are recommended and the longer becomes the run time that is needed. Usually, the owner’s manual indicates the max number of cycles in a period of 24 hours. Taking this into account, with the flow rate, would help in determining what would be right for you. With higher flow rates, the basin’s diameter needed increases. 

Therefore, if you’re looking for the right sewage pump for your system, then make sure to answer these questions beforehand.

Understanding the importance of water pump safety

Whether you are using sea water pumps, or any other kind of pump, it’s important to remember to take out the extra amount of time for learning about the pump safety. When it comes to submersible water pumps, they do not really seem dangerous. However, if they aren’t fitted & operated properly they can cause personal injury, which at times can be fatal.

Therefore, this blog is devoted towards sharing a few tips on water pump safety. Although, this blog does not include every tip there is to know, but it is intended for reminding you of some of the basic ones.

Have a look at the following:

1. Owner’s manual

It does not matter whether its seawater pumps, or dewatering pumps, or which brand’s pump you have decided to purchase. Every company out there, has the information on how to operate their own manufactured pumps, that too with the highest level of safety possible. Although you may think that the safety fundamentals are always the same, and it is true, the specifics of it, often differ. This is where it depends on which brand as well as what type of pump you are getting installed. Therefore, you should make sure that you read the owner’s manual provided with the pump & comply with the procedures laid down therein.

2. Safety guards

When you are dealing with water pumps, it is highly crucial to always make sure, that all the safety guards both mechanical as well as electrical, are in place while the pump is being operated. Not only should you make this sure with the safety guards, but also with the shields of the water pump being operated.

3. Control device

All pump manufacturer will advise you to install safety device like control panel along with its pumps. Many a times this suggestion is treated as an optional thing. However, it is advisable not treat this as an option, but to look at it as necessity, as it will help you in long run if there is any malfunction with the pump. Many reputed manufacturers have features which gives you inbuilt protection against Overheating, Mechanical Jamming, Dry running etc, when connected to control panel.

Apart from these three basic tips, there are a few others, that teach to never use a water pump for fluids that it wasn’t designed for, to always keep the pump at least 3 feet away from the walls and other equipment during its operation, to never use a pump in an explosive or flammable surrounding etc.
