HW Mixed Flow Pump

Product Features

1,Compact, lightweight structure with reliable operation, high efficiency and easy maintenance.

2,Two drive options: direct-coupled drive or variable-speed drive, adaptable to electric motor or diesel engine; specify power & speed at order for correct coupling/pulley configuration.

3,Standard impeller rotation: counterclockwise viewed from suction flange; exception: 650HW-5/-7/-10 rotate clockwise.

4,Impeller trimming or alternative impeller (marked “A”) available to adjust hydraulic performance for wider application scope.

5,Adjustable clearance (0.3~0.7mm between impeller & pump cover via paper shims) to maintain efficiency and avoid friction or backflow.

6,Packing shaft seal assembly prevents air ingress and liquid leakage; replaceable shaft sleeve protects pump shaft against abrasion.

7,Pump shaft supported by single-row radial ball bearing, lubricated by oil or grease. Top tapping on pump casing for priming or vacuum pump connection.

8,Optional spare parts vary by size:

150~300HW: inlet/outlet elbows, flexible elbows, foot valve, pulley/coupling

400~650HW: inlet/outlet elbows, check valve, pulley/coupling

Main Application

Farmland irrigation, municipal & industrial water supply and drainage projects.
