Important Considerations in Selecting a Slurry Pump - DAE Pumps

This article will provide information on the most critical factors when selecting a slurry pump for your application. First, you must ensure that the pump you purchase fits your specific application requirements. The selection of a slurry pump should include proper pump size, power requirements, slurry characteristics, and discharge head requirements.

To select the proper pump size, you must first determine the flow rate and head required by your application. The flow rate is the function of the speed of the pump and the impeller diameter. The head is a function of the impeller design, the number of impellers, the pump speed, and the fluid density.

Selecting the right Slurry Pump

Many pumps can be found on the market, but most are specifically designed to serve a particular purpose. Pumps designed to move thin fluids differ from pumps designed for heavy, thick-laden, abrasive, or abrasive materials. Because of the differences in the design of various pumps, you must choose the right pump for the application. For example, if you need to move much liquid quickly, you will want to select a pump with a high flow rate. However, if you are forcing a liquid with many solids, you want to use a pump. Pumps come in many different varieties, each designed for a specific purpose. For example, if you are trying to move water with much sand, you would want to use a centrifugal pump.

The slurry pump moves thick materials such as slurries and gravel. As the name suggests, a slurry is an amalgamation of two or more materials, such as water and crushed rock. Slurry pumps can move thick materials from their source to the pump and downstream to the destination. This is done using a high-pressure water stream to push the slurry through a pipe. The slurry is then forced through a series of valves and into the pump.

Because of their nature, slurry pumps can pump high-viscous and solid-laden liquids without clogging. Slurry pumps are distinguished by their ability not to choke. They can be used in extreme environments, such as mining and oil and gas extraction, and are also helpful in other sectors, including dredging and oil and gas. Dredging removes sediment and debris from the bottom of bodies of water and is often used to maintain shipping channels.

DAE Pump’s Premium Heavy-Duty Pumps

The DAE Pump has long been regarded as one of the most reliable self-priming pumps with high specific gravity and viscosity. It is specifically designed for applications that transfer heavy, abrasive, or solid-laden materials. The pump’s non-clogging design includes an extended wetted path with an open rotor. The pump can move large amounts of viscous material without clogging or downtime. The pump is also self-priming, meaning it can start and stop without any issue. The pump can also run dry without any damage to the pump itself.

Meager cost of ownership

Choosing the right pump for you is not just about whether it meets your requirements. It also considers the cost of ownership and the total amount of time your pump will use. The DAE Pump can pump viscous or high-specific gravity materials that have a volume exceedingly high in solids. This reduces the overall cost of pumping the material. Pumps that use high amounts of water to move viscous material can significantly reduce profit margins. This is because the water can quickly break down the pump’s seals and bearings, leading to extensive repairs that can be very costly. The high-water content in the material can also lead to clogging and other issues that can reduce the system’s efficiency.

Materials of Construction

The DAE Pump is constructed from the finest materials. It is very rugged and abrasion-resistant, chemically compatible with most fluids, and can withstand all that’s often involved in the abrasive and high-viscosity applications to expand and contract, which can lead to clogging and other problems—causing the material to expand and contract block, and other issues. The expansion and contraction can also cause the material to become clogged, leading to other problems.

what choice in pump type? - Pump engineering - Eng-Tips

I have a fundamental question.

What informs the type of pump for a specific application and what informs those choices?

From experience, I find the Centrifugal horizontal split case being deployed for Fire fighting purposes?
Any reason(s) why and any referals to that effect?

Also, I noticed that LPG pumps used the multistage centrifugal pumps.....any reason(s) and referals

Thanks and Regards

'Lekan It really depends from the operating conditions case by case, i guess.

In my experience in water industry, I used monocellular pump for head up to 100 m and from low flow to - m3/h

Horizontal Multistage pumps from 60 m head up to 500-600 m head and flow up more m3/h

Vertical multistage up to 240 m for boosting genrally let say, or due to space limitation

Horizontal split pump double volute, for head up to 250m but higher flow capacity ( m/h3), in parallel it can handle high flow applications (like m3/day)

At the end of the day, very often I had multiple solution to handle required service, and choose according efficiency and cost. If you look carefully you might find for flows which are capable of being produced by end suction centrifugal pumps of 150 - 200mm dia discharge are used and HSC pumps after that - this is based on economics of manufacture.

As for LPG pumps (not an area I know or deal with) I would think that multistage pumps are used as the heads generated tend to demand this pump style. Usually in warmer climates with ambient temperature highs ranging 40~58 degrees Celsius under sunlight;It is observed that vertical multistage(submerged barrel sump type) centrifugal pumps perform much more efficiently as compared with horizontal multi-stage pumps.
Reasons most probably

liquid LPG NPSH available remains better in 1st type case as well as sunlight exposure impacted high temperatures Stay at minimum.

Whereas for horizontal multistage pumps both the items are at Risk;
As for same pipeline configuration,grade levels we observe relatively lesser NPSH available& Higher temperatures effect state of LPG i.e. partial vaporisation thus cause vapour locking/loss of efficiency.
