Vertical long shaft sewage slurry pump

■Flow rate: Q=17～3500 （m³/h）

■Total head: H=6.5～100 (m)

■Speed: n=980-1470rpm

■S.g.: γ ≤1.15

■Temperature: T=0～80℃

■Pump diameter: 80～600mm

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

■Compact structure takes smaller space, which is benefit to the complete arrangement of steel rolling process.

■Standardized sectional length of pump shaft to meet different submerged depths.

■Guide bearing adopts the material of high-molecular polymer with water lubrication.

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

■Especially suitable for pumping the ferric oxide scale sewage of steel industry.

■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.

■The guide vanes can work in series,maximally 4 stages.

■Shafts are connected by a special method with high precision,therefore,the submerged depth is up to 10 m.

■The pump shafts are supported by guide 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 for pumping sewages with solids, like ferric oxide scale sewage, fluids with mud and sand, pulverized coal...

■Especially suitable for pumping the ferric oxide scale sewage of steel industry.

■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%.
