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.

Submersible Slurry Pumps

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.

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.
high head submersible pumps

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.

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.

submersible 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.
submersible sewage pumps

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!

Desalination - Understanding the Concept

Being a leading Indian manufacturer of submersible pumps, Darling Pumps has been the Chief architect of submersible pump revolution in India. Our new & innovative product line has set a benchmark for other to follow and has thus always kept us one step ahead of the market. We offer a wide range of sewage, slurry and dewatering submersible pumps in India and countries abroad. To add to our innovative product line, we have introduced pumps for desalination. A unique concept, desalination is getting a lot of attention these days.
In this blog, we will be discussing about the process of desalination. Moreover, we will also be discussing the various methods that one can use to execute the process of desalination. For starters let’s take a look at what the whole process of desalination is all about.

The Process of Desalination
The process of desalination is used in order to extract mineral components from saline water. Put in simple words, desalination means the removal of  minerals and salts from a target substance.
When water is to be produced for human consumption or irrigation then the saltwater is desalinated for the same. Salt is one of the by-products of desalination. When we talk about the modern interest in the process of desalination, it is majorly focused on a cost-effective way to provide fresh water for the use of humans. The process of desalination is also used on many submarines as well as seagoing ships. It becomes one of the few rainfall-independent water sources.

The water obtained after the process of desalination is generally more healthy than the water that is obtained from groundwater and rivers. Moreover, it is found that there is much less salt as well as limescale in the desalinated water.
There are various methods attached to the execution of the process of desalination. Each method has its own advantages as well as disadvantages. Let’s have a look at the list of these methods -
  • Vacuum distillation
  • Multi-stage flash distillation
  • Multiple effect distillation
  • Vapor-compression distillation
  • Reverse osmosis
  • Freeze-thaw
  • Solar evaporation
  • Electrodialysis reversal
  • Membrane distillation
  • Wave-powered desalination
Every seawater desalination method consumes different amounts of energy. This includes thermal energy as well as electrical energy.
When we think about the costs that go in while executing the process of desalination, there are various factors that decide this. A few of these factors include the type of facility, capacity, feed water, and location. On top of these factors some other are energy, financing, labor, as well as concentrate disposal.
Another challenging factor in desalination is pumping process. Not all pumps & metals which are available in market can work in sea water. Darling Pumps over the years have successfully supplied pumps for many sea water related applications & pumping. The metal used here is exclusive & very reliable.
Just for your information, for desalination, type of pumps is less relevant compared to the MOC & its reliability. Darling Pumps is proud to offer pumps for desalination. We  have offered pumps for Sea water in Duplex or SS316L series. For more information on desalination, get in touch with us at +91 99819 92833.

All about Sewage Pumps



Whenever sewage-pumping is done, but on a smaller scale or on a larger scale, then submersible sewage pumps has to get into the picture.  A dramatic growth of the submersible pump for sewage pumping has been witnessed since the 1950’s. However, before we get into any more of this, we need to acknowledge the story step by step.  
Here goes.
What is sewage treatment?
The sewage treatment is a process where contaminants are removed from waste water / sewage or effluent.  This process would include biological, physical, and chemical processes that remove these contaminants. It further produces treated water which is environmentally safer. This is also called recycled water. A semi-solid waste or slurry, known as sewage / sludge is usually a by-product of the sewage treatment. This undergoes further treatment before it can be suitable for land application or disposal. 

Sewage Pumps | Submersible Pumps


What are the classes of submersible pumps?
There are typically three classes of submersible pumps that exist.
      1. Smaller submersible pumps
This type of submersible pump is used for light duty & for domestic applications. 

      2. Larger submersible pumps                                                                                              
This type of submersible pump is used in industrial and municipal applications. They are used to pump sewage as well as all types of industrial wastewater. 

     3. Submersible chopper pumps
Submersible chopper pumps are used for churning larger concentrations of solids, whereby large solids particles are shredded to a pumpable form. This in turn can avoid clogging of pipe due to large solids. These are generally used in industrial wastewater and domestic applications.
Submersible pumps are normally used where drainage by gravity is not possible.

What is the famous range of sewage pumps?
Some of the important series of sewage pumps are submersible non clog pump - Unclog Series pumps & Vertical Wet Pit Series - Enviro Pumps & Sump Pumps. 

What are these pumps ideal for?
The above series of sewage pumps are ideal for pumping heavily contaminated water, sewage, effluents, and sludge in variety of Domestic, Industrial & Municipal applications. These pumps are very much ideal for pumping Industrial Waste & Effluents, Govt. & private ETP & STP Plants, pumping Raw Sewage, Sludge Removal, Lifting Stations and Underpasses, Sewage works, River Pollution Cleaning, Open Cast Mines, Tanneries & many more similar applications.
The domestic application includes removing of heavily contaminated water from collection pits, colony settling tanks, private pumping stations or treatment plants etc.
Similarly, the commercial application includes pumping sewage in hospitals & hotels, IT / BPO centres etc. 
On the other hand, the industrial application includes pumping heavy duty sewage / sludge in industries such as paper, cement, Pharma, steel etc. These pumps are very apt for pumping industrial waste from collection pits, settling tanks etc.  
It also be used for various municipal applications like sewage disposal and mass transfer of sludge etc.
