1.General description
NZG(S) Series Slurry Pump delivering the slurry with high concentration with the high head.
2.Introduction
In order to meet the requirements on the development of mining, the power plant, metallurgy and coal industries, our works has designed and developed NZG(S) Series Slurry Pump with CAM modern design, optimal hydraulic performance,high efficiency and lower abrasion rate.
The casing in double casing structure and its outer casing is made of grey cast iron or ductile cast iron according to the work pressure, which ensure the safety of series application.The wet parts also adopt special alloy material, and have good performance of anti-abrasion and anti-corrosion.
NZG(S) pumps can adopt centrifugal seal with packing seal, packing seal and mechanical seal.Broad passage, good anti-clogging performance, excellent performance of NPSH. Reliability design ensures long MTBF (mean time between events).The metric bearing with oil lubrication, setting lubricating and cooling systems reasonably ensure the bearing operate under the low temperature.

Note: Quantity range recommended:50%Q’≤Q≤100%Q’(Q’Appropriate to capacity at highest efficiency point).
2.NPSH:appropriate to point Q recommended at highest speed.

Application NZG(S)Series Slurry Pumps are widely used for handling the mixture of abrasive and corrosive solids in power, metallurgy, coal, building materials, chemical industry departments, especially for removing ash and sludge in power plant.  NZG(S)Series Slurry Pumps are also used in mining,petrochemical,coal washery,dredging,and other industrial departments,ect.

NZG(S)200 is used in Golden mining in Africa
