Slurry pump is normally used to transport abrasive and corrosive media running in high speed. Therefore, the material is very crucial to pump’s service life.

Most Excellence horizontal slurry pumps are double-casing with interchangeable wet parts for the convenience of pump maintenance. The casing is usually made of gray cast iron or ductile cast iron according to working pressure. Ductile cast iron can be strengthened by heat treatment.

As for the wet parts, the most commonly used are alloy and rubber. For slurries of high abrasion, pump made of high-chromium alloy such as KmTBCr27 are more suitable. Natural rubber and synthetic rubber have better performance in strong corrosive applications, and rubber service life is prolonged by adding antioxidants and anti-aging agents.

Other anti-abrasive materials such as EPDM, Hapalon, Hastealloy, CD4MCu are also used, but in some special applications.
