01 Slurry pump and spare parts 1.5/1B-AH 3/2C-AH

Design Features of Naipu Horizontal Slurry pumps and spare parts √ 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. √ Volute 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 moulded elastomer. √ Elastomer seal rings back all liner joints. √ Pump 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 moulded elastomer impellers are completely interchangeable. √ Cast in impeller threads require no inserts or nuts. High efficiency and high head designs are also available. √ Throatbush - wear is reduced and maintenance simplified by the use of tapered mating faces to allow positive accurate alignment during assembly and simple removal. √ 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.
