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.

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.

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
