Product Details

D horizontal multistage centrifugal pump:

D horizontal multistage centrifugal pump adopts the principle of centrifugation and the hydraulic model of energy-saving products. D,DG pump is a multistage, segmental centrifugal fresh water pump, which is suitable for water supply and drainage in mines, factories and cities. D,DG horizontal multistage centrifugal pump is used for conveying the fresh /clean water or other similar liquids without solid particles and abrasive matter. The pumped clean water does not contain the suspended matter. The temperature of the transferred liquid is from -20℃ to 80℃.

Model meaning:

Example 80D12*5, 80 -- pump suction inlet diameter (mm), D -- multistage, segment-type centrifugal fresh water pump, 12 -- pump head (m), 5 -- pump stage is 5.
