Norman - Model NHR Series -Slurry Pump

General Description
NHR 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 abrasive corrosive slurry with high concentration, PH 3-14, liner natrual rubber, Polyurethane, Neoprene or Buna-N material.

Introduction

• The frame plate liners for NHR series pumps have replaceable wear-resistant rubber liners. The impellers are made of natural rubber liners. It has nearly the same constructure with NHM.
• 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.

The type of NHR pumps are also using for handing strong abrasive, high density slurries and low density, high head slurries in the metallurgical, mining, coal, power, building material and other industrial departments etc. It is suitable for the corrosive slurry usually. In some ore dressing, some bigger NHR series pump also would be used to transport the fine ore or tailings with weak abrasion.

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.
