APPLICATION:
Suitable for the transportation of pure water or liquids with tiny size solid particles. HD series high pressure multi-stage centrifugal pump is designed for oil field water injection and for the transportation of high pressure liquids under any other conditions.
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 suction can be either horizontal or up direction. 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 can be used for the suction, stage and discharge casing of type HD(HDF) high pressure multistage centrifugal pumps.
SHAFT SEALING
The shafts of these pumps are sealed by soft-packing and cooled by cooling water. In the region of shaft sealing, the pump shaft is protected by renewable sleeve
The mechanical seal can be used according to the customers’ requirement.
BEARING AND AXIAL BALANCING DEVICE
The rotating assembly is supported by sliding bearings on both ends of the pump shaft. The bearings of pump are forced-lubricated. The oil supply system is equipped for type HD(HDF) pump. The axial thrust of rotor is balanced by balance disc. And the thrust bearing is also provided which is used to bear extra 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 customers’ requirements. The pump can be driven by turbine of motor.
The rotating direction of pump is clockwise when viewed from the driving end.
