Product Details

D,DG multistage horizontal single suction sectional type centrifugal pump is used to convey clear water or other liquids similar to water.

D multistage centrifugal pump is used to transfer the water with temperature lower than 80 DegC and widely used for water discharge in mine, factories and cities etc.

DG Series multistage pump is used to transfer the water with temperature lower than 105 DegC and widely used for water supply of various boilers.

Medium

D multistage pump is used for clear water and DG multistage pump is used for water supply of boilers and water temperature is higher than 100 DegC.

Material:

D multistage pump is normally made of cast iron and DG multistage pump is normally made of cast steel for the high head and medium with high temperature.

Structure:

D multistage pump is without cooling system.

DG multistage pump is with cooling system.

D,DG multistage pump is mainly composed of stator, rotor, bearing and shaft seal:

The stator part is mainly composed of suction segment, middle segment, discharge segment and guide vane, and each segment is clamped with tension bolts to form a workroom. D pump is with general horizontal suction and vertical discharge. D pump used for oilfield water injection, pump inlet and outlet are vertical upward. DG type pump is with vertical out and inlet .

The rotor is mainly composed of shaft, impeller, balance disc and shaft sleeve. The axial force is balanced by the balance plate.

The bearing is mainly composed of the bearing body, bearing and bearing gland. The bearing is lubricated with grease or thin oil.

The shaft seal adopts soft packing seal, which is mainly composed of inlet section and sealing box, packing and water retaining ring on the tail cover. D - type pump water seal water from the pump pressure water. DG pump water seal water from external supply.

The drive pump is driven directly by the electric motor through an elastic coupling. Look at the pump from electric motor end, the pump rotates clockwise
