Performance and benefits

      The suction port and the discharge port of the double suction pump are both below the axial line of the water pump and are horizontally perpendicular to the axis. It is easy to maintain, no need to disassemble the inlet and outlet pipes and electric motor, high efficiency and energy saving, and wide application range.

     The S-type single-stage double-suction horizontal open centrifugal pump is a new energy-saving horizontal medium-opening pump, which is mainly composed of a pump body, a pump cover, a shaft, an impeller, a seal ring, a bushing, a bearing component, etc., and a suction port and a discharge port thereof. All of them are under the pump shaft line. When the valve cover is removed, all the parts can be removed for maintenance. Other liquids for conveying clean water or physicochemical properties similar to water can be used to transport multiple sediment water or various corrosive liquids by changing the pump structure and material according to user requirements. Its performance is in line with JB/1050-93 "single suction double suction water centrifugal pump type and basic parameters

"standard.

About the structure

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 unnecessary to remove the water inlet and outlet pipelines and motor (or other prime movers). The pump moves CW viewing beginning 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(1), pump cover (2), impeller(3), shaft(4), dual-suction seal ring(5), muff(6),bearing(15) 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.

Both pump casing and cover form the working chamber of the impeller and there are threaded holes for mounting vacuum and pressure meters on the flanges at both inlet and outlet and for water draining on the lower side of them.

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.

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.

The pump is driven directly by means of connecting to it via an elastic clutch. (Set up a stand additionally in case of a rubber band driving).

The shaft seal is packing seal and, to cool and lubricate the seal cavity and prevent air beginning getting into the pump, there is a packing ring between the packing. A small volume of high pressure water flows into the packing cavity via the tapered beard during the pump's working to act as a water seal.
