HD Horizontal Multi-Stage Pumps

Introduction:

HD series centrifugal pump is horizontal single casing and multi-stage, the casig is supported by foot or centerline, which is applied in petrol-chemical industry, power station, the liquid is pumped including the petrol, the finishing oil and the liquefied gas which are free with soild, and high temperature and pressure liquid, such as methane, ethane, propane, and ethylene. The design and manifacturing conform to API 610 specification.

Performance:

Applications:

Petroleum industry

Water supply equipment

Power plant

Pipeline pressurization

Structural Features:

HD type pump is radial split sectional structure, in general, the discharge pipe is upward, and the suction one is rightward(from the driving end). The location for discharge and suction pipe is changeable, and it is allowed to have other drain pile. Futhermore, there are two varying impeller and diffuser for each size, so the effiency area is big; the renewable ring provides a sealing function between the impeller and casing, the axial stress that produced by each impeller is balanced by balancing devices. For example, to balance the axial stress by balancing drum, the rasidual strength is stood by bearing.

The bearing is radial rolling bearing, the residual strength is stood by bearing.

The beraing is radial rolling bearing, the residual axial thrust is balanced by centripetal thrust ball bearing, providing oil and grease lubricating. The shaft seal sould use packing or mechanical seal, which one is chosen by the orders.

The motor driven directly through diaphragm coupling, the rotation dirction is CCW viewing from driving end.
