Submersible Slurry Pump
Wear Resistance Core: Specialized for High-Concentration Slurry Conveyance
Specially designed for conveying highly abrasive slurry containing high-concentration solid particles, slag, sediment, etc., the Submersible Slurry Pump adopts super wear-resistant materials and impact-resistant structures, and can operate completely submerged in high-concentration slurry. It is a key equipment for slurry treatment in industries such as mining, metallurgy, and construction. The Submersible Slurry Pump adopts a "high-chromium alloy impeller + thickened pump body" structure. The centrifugal force generated by the rotation of the impeller not only realizes slurry conveyance but also reduces the wear of particles on the pump body through a special flow channel design.
Structural Design and Core Performance
Structural highlights: the impeller is cast with high-chromium alloy (Cr27), the hardness reaches above HRC60; the pump body adopts a wear-resistant alloy liner, and the replaceable design reduces maintenance costs; the motor adopts a sand-proof seal structure to prevent slurry particles from entering the motor cavity.
