1. Mainly slurry pump spare parts
Designed and built for long life with low maintenance
Shaft sleeve:
A hardened, heavy-duty corrosion-resistant metal sleeve with "O" ring seals at both ends protects the shaft.
A slip fit allows the sleeve removed or installed quickly.
Centrifugal shaft seal:
A large percentage of duties allow the use of the centrifugal seal which eliminates the need if sealing water.
Gland shaft seal:
A packed gland type shaft seal is also available and can be fitted with a low flow flush seal water arrangement.
Shaft and bearing assembly:
A large diameter shaft with a short overhang minimizes deflection and vibration. Heavy-duty roller bearing are housed in a removable bearing cartridge.
Pump base:
A minimum number of through bolts hold the pump casing to the frame. A means of impeller adjustment is provided in a convenient position below the bearing housing.
Out casing:
Split outer casing halves if cast or ductile iron contain the wear liners and provide high operation pressure capabilities.
Impeller:
The impeller may be either moulded elastomer or hard metal.Deep side sealing vanes relieve seal pressure and minimize recirculation.
Cast-in impeller threads are better suited for slurries.
Interchangeable hard metal and moulded elastomer liners
Mating faces in hard metal liners are tapered to aloe positive alignment during assembly and aloe components to be easily removed for replacement.
Hydraulic seal rings give positive sealing between mating faces.
