D, DF type multi-stage centrifugal pump is a single shell horizontal multi-stage segmental centrifugal pump, with horizontal suction and vertical discharge. The pump adopts a balanced drum and thrust bearing structure to balance the axial force of the pump, which can effectively avoid the transportation of impurity particles and the damage of the balance mechanism and bearings under frequent starting conditions of the pump. The bearing adopts thin oil lubrication for rolling bearings, and can be cooled by air or water cooling according to the temperature of the conveying medium.

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