horizontal multistage centrifugal water pump
4 year agoHorizontal multistage centrifugal water pump is widely applied to supply water of low or high pressure boiler. Horizontal multistage centrifugal water pump is also used for high pressure water supply and drainage of industrial and urban.
Horizontal multistage centrifugal water pump, all the impellers are stacked in single direction on the same pump shaft. The rotors are perfectly dynamically balanced and the maximum stages can be up to 12 stages. Horizontal multistage centrifugal water pump has advantage of stable performance and superior in quality.
