Self-Balancing Multistage Water Pump

1. Introduction Of Self-Balancing Multistage Water Pump

MZD series Self-Balancing Multistage Water Pump is new designed horizontal multistage centrifugal pump. This series pump has new structure, high efficiency, more wide performance, long operation by using advanced hydraulic model. Marvelu offers a wide range of self-balancing multistage pumps in stainless steel and cast iron.

We have passed ISO9001:2000 quality system certification, strictly control the pump design, production and service, totally make sure the pump quality.


2. Working Condition Of Self-Balancing Multistage Water Pump

 Capacity: 7.5~864m³/h

 Head: 46~2070m 

 Temperature: -60℃~400℃

 Material of Construction: HT200,QT600,Cast Steel, SS304, SS316L, Duplex Steel


3. Self-Balancing Multistage Water Pump Advantages

a) With symmetrically arranged impeller rotor components, axial forces generated by all levels of symmetrical impellers forces offset each other and automatic balancing of huge axial thrust within pump cavity can be realized without disc structure.

b) Good centering of impeller and guide vane channel and efficiency will not significantly drop as balancing disc wears and rotor components move forward. No leakage of balancing water reduces loss of volume and improve pump efficiency and pump efficiency is on average 2~5% higher than normal DG pump.

c) Excellent hydraulic model and design, unique first stage double suction impeller, forging casting, reliable anti-abrasive materials make sure the pump with excellent NPSH, pump work steady, no noise.

d) It can change mechanical seal, bearing without disassemble the inlet and outlet pipes.
