Why Do You Need A Slurry Pump?

May. 26, 2021

When it comes to slurry transport, familiarity with pumps and pump spare parts is essential. However, it is also important to understand what is included in each element of slurry transport. This understanding begins with a few basic questions: "What is the difference between a slurry pump and a water pump?" "What makes a slurry pump different? Next, the ceramic slurry pump supplier will share them with you.


Slurry pumps vs water pumps

Slurry differs from other fluid types by the presence of solids (gravel, copper or sand) in the liquid. Although in many cases the fluid is water, slurries may contain solvents, such as acids, alcohols or petroleum. These non-aqueous components, whether solids or solvents, must be pumped using a slurry pump.

Slurry types

In contrast to the narrow and often inexpensive components of pumps, the large replaceable slurry pump parts are made of robust and often specialised materials. These components enable the pump to move almost all types of solids in the slurry efficiently and safely. Pumps, on the other hand, lack the hydraulic capacity to move solids and cannot withstand the particle wear and chemical corrosion that slurry can cause.


What makes a slurry pump different?

Slurry pumps can withstand a wide range of wear and tear due to the following characteristics: large impeller diameters, shafts, bearings and internal passages as well as heavy duty construction. On an industrial level, slurry pump functions incur higher upfront and operating costs compared to water pumps. However, only slurry pumps are effective for the hydraulic transfer of solid materials, where the long-term benefits outweigh the initial costs.


The key to the success of a slurry pump is the generation of centrifugal force, which pushes the material outwards from the centre of the pump. This is the opposite of centripetal force, which pushes the material towards the centre. Mud pumps must operate on the centrifugal principle because the force that imparts speed to the mud accelerates the conveying process. On the other hand, centripetal pumps are impractical because the solids in the slurry accumulate rather than flow freely.


Ceramic slurry pumps

Ceramic slurry pumps are available as an option to rubber slurry pumps, metal slurry pumps etc. The main material used in ceramic slurry pumps is silicon carbide. Different manufacturers have different processes, mainly including resin-bonded silicon carbide and sintered silicon carbide.

Features of ceramic slurry pumps

The most important feature of ceramic slurry pumps is that they are both wear and corrosion resistant and their performance is much higher than that of alloy and rubber pumps.


After years of metal selection plant tests and data feedback, under the same working conditions, the service life of ceramic slurry pumps is generally 3-6 times that of high chromium alloy pumps, while the price of silicon carbide materials is lower than the high price of high chromium steel, duplex steel, etc., so that ceramic slurry pumps also have a great economic advantage over first-class alloys in terms of raw material prices.


Advantages of SIC slurry pump spare parts

1. Ceramic slurry pump spare parts have a service life 3-5 times longer than that of high chrome alloys and are more wear resistant. 

2. Excellent chemical stability, super acid resistance, suitable for all kinds of pH 0-12 acids and bases (except hydrofluoric acid) and solvents, high oxidation resistance.

3. Resistant to the impact of high and certain concentrations of large particles, some products can challenge the coarse grinding stage.

4. Excellent resistance to thermal shock.

5. Resistance to high temperature thermal shock. 

6. Small density, light weight of parts and high efficiency.
