DG type segmented high pressure boiler feed water pump--Zibo Luzhong Industrial Pump Factory

DG type segmented high pressure boiler feed water pump

This series of pumps are single-suction, multi-stage, segmented centrifugal pumps, used for high-pressure boiler water supply in medium-sized thermal power plants or water injection in oil fields. The maximum medium temperature is ≤160°C. The suction and discharge ports of the boiler feed water pump are vertically upward, and the suction port of the water injection pump is on the side. The rotor of the pump is supported by sliding bearings at both ends. The bearings are forced to be lubricated by an auxiliary oil pump, and cooling water can be introduced into the bearing chamber.
