Fire Fighting Pump Industrial Electrical Dewatering Seawater irrigation water pump

1. QS  high capacity water pump double suction volute pump split casing pump is used to deliver clear water without solid particles or liquid similar to clear water physically and chemically.

2. The split casing pump is designed with single stage double suction structure, which means water flooded into pump through two sides of impeller, thus the capacity of pump will be much bigger than regular one.

3. Pump could be equipped with diesel engine and cart to easy to move.

4. Widely used in water works, agricultural irrigation, draining pump station, electric power station, air-conditioning circulation water, industrial water supply system, shipbuilding industry and general use in oil refining industry.

a. Double suction water split case pump is suitable for mine.

b. Suitable for power station.

c. Suitable for agriculture irrigation.

d. Suitable for water supply and drainage in factory.

e. Suitable for transporting pure water or liquids with physical and chemical properties similar to water.

1. 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.
2. 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.
3. 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.
4. 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.
5. 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.

6. The flexible couplings connect the pump with the motor directly. For pumps driven by belt, there must be an
intermediate bracket fitted for supporting the belt pulley.
8. The close running fit between the wearing rings and the impeller minimizes the leakage of water back into the
suction part. The rings protect the casing from wearing and can be promptly replaced with the spare parts when
they have been worn out.
9.The shaft seal is soft packing. The stuffing ring is fit between the packing in order to prevent air from leaking
into the pump and to cool and lubricate sealing case, and while the pump is working, a small amount of
high-pressured water flows into the packing case through the concave notch on the pump cover to function as
water seal.

10. The appropriate leakage from the packing case is at 10 to 20 drops per minute.
