What are slurry pumps and their types?

In the field of slurry pumping, various types of special pumps are used, such as ejectors to positive displacement pumps, but in practice, the most common pump in the field of slurry pumping is the centrifugal pump. In the slurry pump, centrifugal force is used to create kinetic energy for the slurry. Please contact our experts in the company to buy slurry pumps or to know the latest price of slurry pumps.

Technical specifications of slurry pumps

The body material of slurry pumps is often made of anti-wear cast iron or anti-wear metal alloy, and it can also be made of plastic. Slurry pumps are used to move and transport materials containing solid particles. One of the important applications of this pump is to use it in mines and to transfer drilling mud, and sometimes these pumps are also called mud transfer pumps. Given that mud transfer pumps (slurry) They are often associated with abrasive materials, in order to protect and increase the lifespan of parts against wear, they use elastomeric or rubber coatings, for this reason, it is also called anti-wear pump or linear pump. Linear pumps are widely used in tile and ceramic industries to transfer slurry and fluids containing silica and similar industries.

What is slurry?

A combination of fluid and solid particles is slur and slur can be of the following two types

 

• • Saturated slurries: usually composed of coarse and rough particles that tend to create non-uniform mixtures. This slurry has high abrasion properties.

• • Unsaturated slurries: usually consist of fine, rough and abrasive particles, which tend to create a stable and uniform mixture and increase the viscosity of the fluid. This slurry has less abrasive properties.

Slurry characteristics

 

• • Abrasion: Abrasion occurs when rigid particles on a solid surface are subjected to pressure and movement, which usually occurs in slurry pumps in only two parts: between the impeller and the throat bush and between the rotating shaft and the fixed packing.

• • Physical Corrosion: Physical corrosion is a type of wear in which the surfaces of the pump parts are destroyed in contact with the solid particles of the fluid. Generally, there are three types of physical corrosion: sliding bed, random impact and directional impact.

• • Chemical corrosion: There are different types of chemical corrosion, including uniform, galvanic, cracking, pitting, granular, stress, and physical-chemical corrosion, which is very important in slurry pumps to protect against physical-chemical corrosion. This corrosion is the result of the wear of an oxide layer formed on the surfaces of the pump that is in direct contact with the fluid.
