Product details

DG type pump is a single suction, multi-stage segmented centrifugal pump used for high-pressure boiler feedwater or oilfield water injection, with a maximum medium temperature of 160 ℃. The suction and discharge ports of the boiler feedwater pump are both vertically upward. The suction ports of DG300-160 and DG250-160 water injection pumps are located on the side. The rotor of the pump is supported by sliding bearings at both ends, and lubricating oil is forced to lubricate the bearings in the bearing chamber through an auxiliary oil pump. The bearing chamber can also be cooled by water.
