Pump Description

diesel engine driven sea water pump

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 125℃.

Both inlet and outlet of this pump are placed under the axial line, horizontally and vertical to the axial line, the pump casing is opened in the middle so it is unneccessary to remove the water inlet and outlet pipelines and motor(or other prime movers). The pump moves CW viewing from the clutch to it. The pump moving CCW can also be made, but it should be specially noted at order.

The main parts of the pump are: pump casing, pump cover , impeller , shaft, dual-suction seal ring, muff, bearing etc. and all of them, except the axle which is made of quality carbon steel, are made of cast iron. The material may be replaced with others upon different media.

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 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.
