NZJA Series Heavy Duty Slurry Pump

NZJA Series slurry pump is horizontal heavy duty slurry pump which can be used in ultra-heavy duty applications from cyclone feed to flotation, regrinding and tailings. Naipu slurry pump can be used widely in iron ore beneficiation, copper concentration, gold ore dressing, potash fertilizer etc. Naipu NZJA series slurry pumps are equivalent to Warman AH/MCR pumps, and Naipu can supply replacements for wet ends on Warman AH/MCR pumps.

750NZJA slurry pumps independently developed by NAIPU are the first in China, and are a world class product. With a flowrate of 15000m3/h, these are the largest pump in mining industry, installed at Erdenet Cu&Mo mine in Mongolia for tailings transfer. 550/450NZJA slurry pumps are installed in Jiangxi Copper, China Gold and EMC in Mongolia.

Overview

Parameters of Design Duty Points of NZJA Series Slurry Pump

Design duty points refer to the rated point designated at the beginning of design of a slurry pump which is usually the highest efficiency point. Working range is increased by adjusting the speed of NZJA slurry pumps practically.

Model Selection of Slurry Pump

Introduction to Model Selection of NZJA Series Slurry Pumps

1. When the model selection is conducted for a NZJA Series slurry pump, the clear water performance curve table for a pump shall be referred to, and the coefficient for the flow range selected is as follows:

1) For slurry of high density and strong abrasiveness, the coefficient of flow range will be 40-80%;

2) For slurry of medium density and medium abrasiveness, the coefficient of flow range will be 40-100%;

3) For slurry of low density and low abrasiveness, the coefficient of flow range will be 40-120%.
