440V 460V 690V Multistage Centrifugal Pump For High Head 100m3/h
Horizontal Ring Section Self-Balancing Multistage Centrifugal Water Pump ZD85-45X7P
It can deliver the clean water, sewage water, corrosive liquid, hot water, seal water and oil liquid by selecting different mater of flow passage parts. It is widely applied to industrial water supply and discharge, high building water supply, fire fighting applications, mining water discharge, long distance water transmit, and boiler water feeding, etc.
Design Features:
* 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 the balance disc structure.
* Unique throtting and pressure reduction devices, odd-level balancing device.
* Using advanced hydraulic model, independent R&D enery efficient products, 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 improves pump efficiency and pump efficiency is on average 2-5% higher than normal pumps.
* By canceling easy-failing balancing disc, pump reliability is greatly improved, maintenance frequency and maintenance cost are reduced.
