HAD Heavy Abrasive Duty Slurry Pump(Repalce AH)
Type HAD pump are cantilevered,horizontal,centrifugal slurry pumps.They are suitable for delivering low density slurries for metallurgical,mining,coal and building material departments.The shaft seal adopts both gland seal and centrifugal seal.
Type HAD pumps operate in high speed with small volumes to save floor area.The frame plates have changeable,wear-resistant metal liners rubber liners and the impeller are made of wear-resistant metal or rubber.
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.
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.
Split outer casing halves of cast or ductile iron contain the wear liners and provide high operation pressure capabilities.
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.
