Introduction
Type AH, HH, M pumps are cantilevered, horizontal, centrifugal slurry pumps. They are designed for handling abrasive or corrosive slurry in the metallurgical, mining, coal, power, building material and other industrial departments etc.
AH(R), HH are also called heavy duty slurry pumps, are used to transport the strong abrasive high density or low density high head slurry. Under the allowable pressure, the pumps of this type also can be installed in multistage series. HH type pump is mainly used for transport low density high head or high density low abrasive high head slurry.
M(R) is a kind of middle duty slurry pump, is used to transport the fine particle size and middle density slurry.
The liner and impeller of AH(R) and M(R) model can be changeable and material can be either anti-abrasive metal or rubber, but material of liner and impeller of HH model only can be metal version. Rubber material wet parts are mainly used for transport the slurry which contains fine, non-sharp particle size.
The shaft seals for type AH(R), M(R) and HH pumps can be adoptable of gland seal, expeller seal and mechanical seal. The discharge can be positioned at intervals of 45 degrees by request and oriented to any eight positions to suit installations and applications.
Advantages
1. Discharge branch can be positioned at intervals of 45 degree.
2. Good replaceability of components with original pump.
3. Wear-resistant metal and long service life time.
4. With greater axial and radial load rating capacity,
5. Discharge direction can be installed at intervals of 45 degrees as request and oriented to any eight positions to suit applications.
6. Suit different working condition.
7. Wide application, high efficiency and easy to maintain.
8. Wide options for impeller.
9. Bearing assembly use grease lubrication.

Construction
The AH type slurry pumps have pump bodies that consist of replaceable wear-resistant metal liners or wear-resistant rubber liners, and impellers can also apply wear-resistant metal material or wear-resistant rubber material. The HH type slurry pumps only apply wear-resistant metal material as their pump bodies and impellers.
Application
AH series slurry pump is widely used in metallurgy, mining, mineral processing, dredging, dewatering, water treatment, coal washing, mill, cyclone feed, tailing, power, building material…etc. various industrial sites. Our pumps are called different names for different working duties: Mineral processing pump, Mill discharge slurry Pump, Booster pump, Feeding pump, Tailing pump, Transfer pump Thickner Underflow Pump, De-watering screen pump, Pressure pump, Concentrate pump…
