APPLICATION:

Suitable for high pressure water feeding process of heavy duty boiler or for transportation of high pressure pure water in any other circumstances.

 

CONSTRUCTION:

The pumps are sectional casing, multi-stage centrifugal pumps. The suction casing, stage casing and discharge casing are rigidly held together by the bolts. The joints between these casings are primarily sealed by means of metal-metal contact. Simultaneously, O-rings are used as auxiliary seals

The forged pieces are used for the suction, stage and discharge casing of type MSHB high pressure boiler feed pumps.

 

SHAFT SEALING

The shafts of these pumps are sealed by soft-packing and cooling water. In the region of shaft sealing, the pump shaft is protected by renewable sleeve.

 

BEARINGS AND AXIAL BALANCING DEVICE

The rotating assembly is supported by sliding bearings on both ends of the pump shaft.Bearings of pumps are forced-lubricated.

The oil system is equipped for type MSH pump. The axial thrust of rotor osis balanced by balance disc. And the thrust bearing is also provided which is used to bear axial force caused by the change of working conditions.

.

DRIVE

The pump is directly driven by the motor through the coupling.

The gear, membrance coupling and hydraulic coupling can be used according to client’s requirements. The pump can be driven by turbine of motor.

The rotating direction of pump is clockwise when viewed from the driving end.
