China Zd Multistage Boiler Feed Hot Water Circulating Pump

Type ZDG boiler feed electric high pressure water pump price

Type ZDG boiler feed electric high pressure water pump is mainly used for conveying water free of solid particles with the temperature of -20 °C ~ 210 °C or physical and chemical properties similar to liquid water.

Type ZDG boiler feed electric high pressure water pump has been innovated on the basis of the traditional forms, abandoning the axial force balancing structure of the multistage centrifugal. Since having no balancing device, there exists none disk friction losses nor balancing return losses,the pump efficiency has been increased by 5-14% than the same category multistage pumps.
