Centrifugal High Chrome Casting Sand Slurry Pump Impeller
Pump introduction
Sand slurry pump is the standard middle duty slurry pump which designed for the continuous pumping of highly abrasive, high density slurries with minimal maintenance requirements. Sand slurry pump is the standard light duty slurry pump which designed for the continuous pumping of light abrasive, light density slurries with minimal maintenance requirements. They maintain high efficiency over the wear life of its components and typically used in process plant transfers, wet waste processes, recycling-washing plants, sand plant duties, heavy minerals processing, mineral recovery and chemical process plant.

Features:
Bearing assembly – a large diameter shaft with short overhang minimizes deflection and contributes to long bearing life. Only four through bolts are required to hold the cartridge type housing in the frame.
Liners – easily replaceable liners are bolted, not glued, to the casing for positive attachment and east of maintenance. Hard metal liners are completely interchangeable with pressure molded elastomeric. Elastomeric seal rings back all liner joints.
Casing – Casing halves of cast or ductile iron with external reinforcing ribs provide high operating pressure capabilities and an extra measure of safety.
Impeller – front and rear shrouds have pump out vanes that reduce recirculation and seal contamination. Hard metal and molded elastomeric impellers are completely interchangeable. Cast in impeller threads require no inserts or nuts. High efficiency and high head designs are also available.
One-piece frame – a very robust one-piece frame cradles the cartridge type bearing and shaft assembly. An external impeller adjustment mechanism is provided below the bearing housing for easy adjustment of impeller clearance.
