HAD hard metal/rubber heavy duty slurry pumps are designed for the most difficult pumping applications for high abrasive, high density or erosive slurry. Extra thick sections at wear point and perfect impeller structure ensures satisfactory performance with long life, and needs minimum maintenance requirements.Rubber lined pump expand applications to chemical products handing, several different rubber options are available to meet different application needs. Especially fit in aggressive applications like mill discharge, tailing transportation.

Shaft sleeve 

A large percentage of duties allow the use of the centrifugal seal which eliminates the need of sealing water.

Gland shaft seal

A packed gland type shaft seal is also available and can be fitted with a low flow or a full flow flush seal water arrangement.

Shaft and bearing assembly

A large diameter shaft with a short overhang minimizes deflection and vibration.Heavy-duty roller bearings are housed in a removable bearing cartridge.

Pump Base 

A minimum number if through bolts hold the pump casing to the frame .A means of impeller adjustment is provided in a convenient position below the bearing housing.

Outer Casing 

Split outer casing halves of 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 allow positive alignment during assembly and allow components to be easily removed for replacement.

Hydraulic seal rings give positive sealing between mating faces.
