Abrasion Resistant Slurry Pump are made of silicon-nitride, silicon-carbide composite sintered ceramic material, and the pump casing uses high chromium alloy. The ceramic parts are second only to diamond in hardness. Under the same working conditions, the service life is 4–6 times that of traditional high chromium alloy slurry pumps. In the mining industry, under the same working conditions, the life of the wear parts is 3–8 times that of metal pumps. Hydraulic loss is low, and the pump maintains a long high-efficiency operating period after wear. This pump can be interchanged with metal or rubber pumps. It is suitable for mining, metallurgy, chemical, environmental protection and cement industries.

FAQ
Q: Why does Abrasion Resistant Slurry Pump use silicon carbide ceramic instead of metal for the wet end parts?
A: Silicon carbide ceramic is second only to diamond in hardness. In the same abrasive environment, its volume loss is far lower than high chromium alloy, duplex stainless steel and rubber. Under high-abrasion conditions, ceramic wet end parts wear at a lower rate and have a longer replacement cycle.
Q: Can this pump be interchanged with existing metal or rubber pumps?
A: Yes. This pump is made of reaction-bonded silicon carbide ceramic and can be interchanged with metal or rubber pumps. For existing ZA series slurry pumps, replacing the impeller, front liner and pump cover upgrades the pump to a ceramic configuration.
Q: Is this pump suitable for handling highly corrosive liquids in the chemical industry?
A: Yes. Silicon carbide ceramic has corrosion resistance and can handle highly corrosive chemical liquids such as strong acids, strong alkalis and oxides. The pump casing is made of high chromium alloy, providing structural support under corrosive conditions. The specific model selection is determined by medium concentration, temperature and flow parameters.
