Feature 

Type AH,HH,M 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 AH,HH,M pumps have replaceable wear-resistant metal liners or rubber liners.
The shaft seals for type AH,M, and HH 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.

Application

AH,HH,M 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
 

Ball mill discharge   Bottom/fly ash, lime grinding    Coal   Coarse sand
Coarse tailings     Dredging FGD    Fine tailings

  1. there is air in the inlet
  2. The temperature of the liquid is too high
  1. Clear the suction pipe and sluice valve.
  2. Lower the height of the suction 
  3. Adjust the water valve and let the pump operate in the defined limits.
  4. Block the leakage.
  5. Lowering the liquid temperature.
8.pump vibrates 1.pump cavitate 
2.The block of the impeller single vane 
3.The no concentricity  between the pump shaft and motor shaft
4.Fasteners or foundation loose
1.Adjust the water valve ,lower the height of the installation,reduce the resistance of the inlet.
2.Clear the impeller
3.Alignment again
4.Fasten the screw,and reinforce the foundation.
9.Bearing is overheat  1.lock the cooling water
2.lubrication is not good.
3.the lubrication oil is not clear
4.the wrong direction of the thrust bearing.
5.there is something wrong with the bearing.
  1. Open the cooling water
  2. Adjust the oil quantity 
  3. Clear the shaft,change oil
  4. According to the inlet pressure,adjust the direction of the thrust bearing.
  5. Change the bearing 
10.Packing short life  The material of packing is not good  Change the packing 
11.pump leak oil 1.High oil level
2.The rubber parts invalid  
3.Assembly problem
1.Lower the oil level
2.Change rubber spares
3.Adjust the assembly
 
12 Pump head leaking  1.The rubber parts not press well Assembly again or press tightly
