Type ZJR, ZJM, ZJH Pump are cantilevered, horizontal, centrifugal slurry pump. They are designed for the handing high density slurries in the metallurgical, mining , coal, power, building material and other industrial department etc.
The frame plates liner and impeller for type ZJR , ZJ(M) pumps have replaceable wear-resistant metal liners or rubber liners.
The shaft seals for type ZJ(R),ZJM, and ZJH Pump may be adoptable of gland seal , expeller seal or Mechanical seal . 
The discharge branch can be positioned at intervals of 45 degrees by request and oriented to any eight positions to suit installations and applications.
Bearing assembly use cylindrical structure, which helps adjust the space between impeller and cover plate liner easily, and being removed completely when being repaired. Bearings use grease lubrication. Here are the drive types, such as V belt drive, gear reducer drive, fluid coupling drive, and frequency conversion drive devices.
Wide performance, good NPSH and high efficiency, the pump of this type may be installed in multistage series to meet the delivery for long distance.


ZJR, ZJM, ZJH pumps are using for handing EPT abrasive, high density slurries and low density, high head slurries in the metallurgical, mining, coal, power, building material and other industrial departments etc.
For example: Coal washery processing, handling with the fine ore and tailings in metal mine, handing combined bottom and fly ash in a thermal power station.

Typical Application
