Long shaft submerged slurry pump

■Flow rate: Q=140～9400 （m³/h）

■Total head: H=12～68 (m)

■Speed: n=585-1470rpm

■S.g.: γ ≤1.15

■Temperature: T=0～70℃

■Pump diameter: 150～1000mm

■Adopted advanced structure and hydraulic models to enable long life operation of high efficiency and stability.

■Compact structure takes smaller space,saving the construction cost.

■Standardized sectional length of pump shaft to meet different submerged depths, which is up to 25 m.

■Grease lubricated bearings can work properly even if the bearings are slightly soaked.

■Secondary impeller design to reduce the pressure, and there are holes on the impeller to balance the fluid pressure to ensure the sealing performance.

■Sectional combination structure enables the sectional maintenance to save the cost of operation.

■Guide vane type submerged pump,impeller is immersed in the fluid,the guide vanes in the middle section pushing the fluid all the way up along the main shaft.

■Impellers can multiply work in series,and the shafts and water guide pipes can be connected to enlarge the usage scale of pump.

■Shafts are connected by a special method with high precision to ensure the alignment and smooth operation of pump.

■The pump shafts are supported by roller bearings;the fluid is separated with shafts by the guard plates.

■Vertical installation with horizontal pump outlet; The rotary part is driven by the motor through the couplings.

Structure drawing is as below

■Pump cover and space guide vanes: ductile iron or steel castings

■ Impeller: cast steel or cast iron

■ bracket: gray cast iron

■Water conduit and protective tube: seamless steel pipe

■Suitable to pump clean water or fluids have close characters with water; The pumping temperature is below 80℃, solid diameter below 10 mm, fluid density below 15%.

■Sewage contains small quantity of particles.
