D. DF type multi-stage centrifugal pump

D. The DF multi-stage centrifugal pump is a single shell horizontal multi-stage segmented centrifugal pump, with horizontal suction and vertical discharge. The pump adopts a balance drum+thrust bearing structure to balance the axial force of the pump, which can effectively avoid conveying particles containing impurities and damage to the balance mechanism and bearings under frequent pump startup conditions. The bearings are lubricated with thin oil from rolling bearings, and can be cooled by air or water cooling depending on the temperature of the conveying medium.

Suitable for transporting water, oil products, chemical media, and other liquids in chemical plants, mines, oil fields, water injection, and urban water supply.
