General

Model QS pump is a single-stage double-suction horizontal split centrifugal pump and used to transport pure water and the liquid of both physical and chemical nature similar to those of water, the maximum temperature of which must not be over 80℃ , suitable for irrigation of farming land and carious hydraulic projects, water supply and drainage in factories, mines, cities and electric stations, waterlogged land drainage etc.

Pump Structure

1. Pump Casing

The volute casing is split on the horizontal centerline with the suction and discharge nozzle cast integral with the pump casing. The upper casing is accurately located on the lower half by the use of dowel pins. The upper casing can be removed to inspect the interior of the pump without disturbing the pipe connections or pump alignment. The suction and discharge flanges contain tapped holes for vacuum and pressure gauge. At the bottom of the flanges, there are tapped plugs for water drainage.

2. Impeller

The impeller is static-balance calibrated, fixed with the muff and the muff nuts in both sides and its axial position can be adjusted via the nuts and axial force gets balanced by means of the symmetrical arrangement of its blades, there may be residual axial force which is borne by the bearing at the axle end.

3. Shaft

The pump shaft is supported by two single-column centripetal ball bearings, which are mounted inside of the bearing body on both ends of the pump and lubricated with grease. The dual-suction seal ring is used to reduce the leak at the impeller

4. Seal Type

There is gland seal type and mechanical seal type.

Direction of Rotation

The pump moves CW viewing from the clutch to it. The pump moving CCW can also be produced.

Material

General material is cast iron, main include pump casing, pump cover, impeller, seal ring and shaft sleeve, shaft is carbon steel. We could also produce as your requirements, such as nodular cast iron, cast steel, bronze and stainless steel etc.
