Vertical Multistage Centrifugal Pumps for Pumping Neutral Clean Liquids

A vertical multistage centrifugal pump is displayed.

Vertical multistage centrifugal pumps are mainly made of stainless steel and cast iron. With the number of impellers increase, the pressure of the outlet also increases accordingly. It is widely used in reverse osmosis systems, industrial liquid transfer, coolant systems, air conditioning systems, boiler water supply, water plant filtration and transfer, water plant divisional water supply, high-rise buildings, hotels, cleaning system, high-pressure washing system, fire control system, car cleaning, ultrafiltration systems, distillation systems, swimming pools, regional irrigation, sprinkler irrigation, drip irrigation and other industries.
