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.

Exploring the world of Submersible Pumps

When it comes to the world of water pumps in general, there are many options. Each pump has a different design and serves a different purpose. They differ in sizes, shapes, capacities, prices etc. They also differ in quality depending on which provider the customer chooses to go for.

However, in this large world of water pumps, there is also a unique category of pumps i.e. the submersible pumps. The general perception is that submersible pumps are good or are available only as sewage pumps. Is it so?

No, today there are few good companies who are offering Submersible pumps for all kind of water processes. i.e. from pumping Clear Water to Pumping Slurry. In this article, we’ll be sharing the very basics of a submersible pump.

• How does it get its name?
A submersible pump is called so because of its ability to operate in fully submerged condition, in water. It is also known by the name of an electric submersible pump.

• The motor of a submersible pump
The motor of a submersible pump is close-coupled (mounted on common shaft) to the pump & is like a heart of the pump. Sealing forms a very important aspect of motor, sealing can be either mechanically sealed or it can be hermetically sealed.

• The basic function of a submersible pump
A submersible pump basically aims at pushing the water to the surface. It functions in this way by converting the rotary energy into kinetic energy and further converting that into pressure energy.

• How does the pump execute this process?
This process is executed by pulling of the water into the pump. Firstly, it goes in the intake. This is where the rotation of the impeller starts pushing the water through the Volute. And then, from here, it finally goes to the surface.

• Why are submersible pumps advantageous?
Few of the major advantages of a submersible pump is that it is self-priming, no suction lift limitations, no negative suction & less power consumption.

Add to this there is no noise pollution, no wastage of surface space, pump is not necessary & last but not the least it also acts as a protection against possible theft.

• A tip of caution for using submersible pumps
The pumps must be fully submerged into the water, as it actually helps to cool the motor of the slurry pump. However, if the pump is used out of water, it may lead to overheating & burning.

In the end, if you are planning to go for a pump, its always advisable to check whether you have an option in submersible pumps & chose are the type that suits your purpose, keep these advantages in mind and go ahead about it. You should however, make sure that the quality you are attaining is great and reliable. For our product details get in touch at 99819 92838.

3 Must Know Submersible Pumps in Pumping World

Being a part of pumping industry over decades, Darling pumps knows that dewatering submersible pumps, sewage submersible pumps, and slurry submersible pumps are the three stars of water pumping world. We are sure you’d be convinced of this too, after reading this blog.

1. Dewatering Submersible Pumps  

    

    One of the most popular stars in this category is dewatering submersible pumps.

They play a major role when it comes to the activity of dewatering. Whether we talk about dewatering of pits, quarries, basements or mass water transfer, the dewatering submersible pumps pull it all off. However, they are majorly used for pumping that dirty water which has chunks of suspended solids. In the modern age, this water pump is used by various fields of businesses. They involve Industrial applications and infrastructure projects etc. Not only this, but our star is also very useful when it comes to domestic applications.

    2. Sewage Submersible Pumps

Being a star, sewage submersible pumps have their own tantrums. By this, we mean that when it comes to running these pumps, it’s always a big task. Or we could say that it was. With time, like everything else, the sewage submersible pumps have also evolved. They have been built with the best and most innovative technology. This addresses the previous problems that used to exist with them. Hence, using this equipment has now become free of jams. They are majorly used for activities like waste and sludge removal. The industrial sections that they are used in are chemical plants, tanneries, sewage works and much more places.

3. Slurry Submersible Pumps

 

As the name suggests, these water pumps work on “slurry”. Slurry is basically an abrasive fluid which is generally a mixture of mud with water or Ash, coal, cement iron ore, iron dust, iron scales with water respectively. It can be settling or non - settling, corrosive or non-corrosive. The main purpose behind the movement of this fluid is to hydraulically transport solids particles. Slurry submersible pumps are the pumps which are used for a major variety of applications. These applications include pumping ash slurry, iron slurry, waste sludge handling, and clean up of sumps, removal of silt built up, waste collection ponds and many more. They are also very useful in the mining industries. 

Therefore, the roles and applications that these water pumps have make them the three stars of the water pumping industry. Darling Water Pumps have the best of all these three stars. Call +91 99819 92838 for details.

Know The Basic of Slurry Pumping

Slurry can be really tough on pumps! Being thick, abrasive & with high specific gravity, slurry is one of the most challenging fluids to move. 

 

What is slurry?

Slurry is a mixture of solids and liquid, generally water. The particles can be both abrasive & non abrasive, although abrasive particles are very much common. The purpose to move slurry can be transporting as much solids particles as possible, hydraulically, along with the given liquid.

Factors to be Considered in Slurry Pumping

• Particle size- d85= 3mm- means 85% of particles have a diameter of 3 mm or less.

• Specific gravity of solids particles (SGs)

• Specific gravity of liquid (normally water which is 1)

• Concentration of solids by volume (Cv)

• Concentration of solids by weight (Cm) (where Cv, Cm is given in % it means it is for slurry)

• Specific gravity of slurry (SGsl)

• Mass fraction (% of particles below 75 μm)

• Shape of particles (Round or Flat)

Characteristics of Slurry

1. Non – Settling Slurry - In this particle size is less than 60-100 μm. A non settling slurry can be defined as a Homogenous Mixture. It is comparatively easy to pump non-settling slurry.

2. Settling Slurry- In this particle size is greater than 100μm. Settling slurry can be defined as Pseudo-Homogenous Mixture OR Heterogeneous Mixture. This is where the demand on slurry pumps increase.

Few Slurry Pump Applications

• Steel Plant- Pumps for mill scale transportation.

• Thermal Power Plants- Pumps for fly Ash slurry handling.

• Hydel Plants & projects- Pump for removing silt and sediment from tailing dams, trenches, channels, Dam gallery, coolant sumps, etc…

• Mineral Processing Units.

• Mines & Quarries

• Various industrial uses like E.T.P, Cement plants, Fertilizer & Pharmaceutical Plants.

• Sand dredging, washing and cleaning.

• Lagoon cleaning & dredging near dockyard and ports.
