Boiler Feed Pump (DG150-86/DG230-102)

Product Description

Technical parameter:

Inlet diameter: 80-200mm
Capacity: 100 - 580 m³
Head: 740 - 2150 m
Power: 132 - 4800 Kw
Voltage: 380V, 3000V, 6000V, 10000V.

The pumps are sectional-casing, multi-stage centrifugal pump, they are used for feeding to degree high pressure or for pumping medium pressure water.

Model DG150-86 and DG230-102 pumps are new type medium pressure boiler feed pump with large capacity and high efficiency. It's a save energy product of replace and good economic for power plant.

The pumps are used for uint and manifold feeding system of all kinds of capacity uint at the power plant.
(1)Temperature under 160 deg C
(2)Pumped liquid with pH5-9
