Model HW pump is a horizontal single stage single suction volute mixed flow pump and suitable for transporting pure water or the other liquid with both physical and chemical natures similar to those of water, with the temperature of the liquid to be transported not over 50 , for the farm land irrigation, industrial and city water supply and drainage etc. multiple places.The pumps performance range: flow 130~9000m /h, head 3.5~22m.
Simple structure, reliable use, easy installation, high efficiency, small body, light weight.
3. Mode of actuation:
Direct and variable actuations. The common movers are motor and diesel engine. Please note the model (power, rotating speed) of the mover so as to make sure of the norms of the clutch or the belt pulley .
4. Water pump direction:
Viewing from the pump inlet, the impeller rotates counter-clockwise generally (clockwise with 650HW-5, -7, -10 pump).
1. Model HW pump mainly consists of pump cover , impeller, pump casing, shaft, muff and bearing body (aperture 350mm) or bearing stand (aperture 400mm) etc. parts (Fig.1
2. The pump cover is connected to the pump casing and the water-in pipe separately. There should a proper interval between the planes of both pump cover and impeller , too small
interval will produce friction; while too big will cause the pressured water inside of the pump to flow back greatly to have the pump efficiency lowered. The practically used proper interval is 0.3~0.7mm (push the pump shaft to the pump inlet) and the interval can be adjusted through increasing or decreasing the paper pad thickness.
