NHM Slurry Pump

NHM Series slurry pump is cantilevered heavy duty metal lined slurry pump,It is designed for handing strong abrasive, high density or low density, high head slurries. Clients from home and abroad are speak highly of its excellent performance, NHM series slurry pumps have become the first selection in metallurgical, mining, coal, power, building material and other industrial departments etc.

1. General Description
NHM Series slurry pump is mainly used for handing strong abrasive, high density slurries and low density, high head slurries in the metallurgical, mining, coal, power, building material and other industry.
Transport the strong abrasive slurry with high concentration, PH 5-12, metal lined.
2. Introduction
The frame plate liners for NHM series pumps have replaceable wear-resistant metal liners. The impellers are made of wear-resistant metal. The frame plate liner and impeller for NHM pump are adoptable of hard metal only.
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.
The shaft seal could use the packing seal, centrifugal seal and mechanical seal. The discharge side can be positioned at intervals of 45degrees 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.
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.
