HDM Medium Duty Slurry Pumps

HDM Series slurry pump is mainly using for handing strong abrasive, high density slurry and low density, high head slurry in the metallurgical, mining, coal, power, building material and other industrial departments etc.

 

The frame plates of this kind of slurry pump have replaceable wear-resistant metal liners. The impellers are made of wear-resistant metal. The frame plate liner and impeller for HDM pump are adoptable of hard metal only.

Bearing assembly of this kind of slurry pump applied cylindrical structure, adjusting the space between impeller and front liner easily, and removed completely when being repaired. Bearing assembly use grease lubrication.

The shaft seal of this kind of slurry pump could use the packing seal, expeller seal and 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.

Here are the drive types, such as V belt drive, gear reducer drive, fluid coupling drive, and frequency conversion drive devices.

They have excellent performance, good NPSH and high efficiency. The pump of this type may be installed in multistage series to meet the delivery for long distance.
