CB Type DG Boiler Feed Pump

DG pump is a single-suction, multi-stage, segmental centrifugal clean water pump, suitable for medium and low pressure boiler feed water, factory, and urban high-lift water delivery. It is used to transport clean water or liquids with physical and chemical properties similar to clean water. The medium temperature is -20℃~105℃ (except DG85-80 and 200DG43, the medium temperature of these two pumps is -20℃-150℃). The pump inlet pressure shall not exceed 0.59 MPa (6 kgf/cm²).

The suction port and discharge port of the pump are both vertically upward, and the axial force of the rotor is balanced by the balance disk. The shaft seal can be a packing seal or a mechanical seal. The rotor support is only used for DG85-80, DG85-67, and DG155-67 with sliding bearings and thin oil lubrication, while other pumps use rolling bearings.EMAC will continue to update the product introduction pages of different standard versions of pumps.
