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.

Slurry Pumps

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.

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.

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.

High Head Submersible Pumps

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. 

Sewage Pumps

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.

sewage pumps

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.
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.

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. 

water pumps

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.
