Brief introduction:

CLWII long shaft sewage pump is an updated product which was developed based on the continuous absorption of the advanced technologies of overseas as well as the self-innovation. The unique design philosophy and decades experience eliminated the problems in the same type pumps,which are short life of bearings,serious vibration,bending shaft,frequently maintenance...It is widely used in the ferric oxide scale sewage and other sewages of steel rolling rotating flow well of steel companies.

1. Flow rate:Q=17~3500 (m³/h)
2. Total head:H=6.5~100 (m)
3. Speed:n=980-1470rpm
4. S.g.:γ ≤1.15
5. Temperature:T=0~80ºC 
6. Pump diameter:80~600mm

1. Adopted advanced structure and hydraulic models to enable long life operation of high efficiency and stability.
2. Compact structure takes smaller space,which is benefit to the complete arrangement of steel rolling process.
3. Standardized sectional length of pump shaft to meet different submerged depths.
4. Guide bearing adopts the material of high-molecular polymer with water lubrication.
5. Sectional combination structure enables the sectional maintenance to save the cost of operation.
6. Especially suitable for pumping the ferric oxide scale sewage of steel industry.

1. 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.
2. The guide vanes can work in series,maximally 4 stages.
3. Shafts are connected by a special method with high precision,therefore,the submerged depth is up to 10 m.
4. The pump shafts are supported by guide bearings;the fluid is separated with shafts by the guard plates.
5. Vertical installation with horizontal pump outlet; The rotary part is driven by the motor through the couplings.

Structure drawing is as below

1. Suitable for pumping sewages with solids,like ferric oxide scale sewage,fluids with mud and sand,pulverized coal...
2. Especially suitable for pumping the ferric oxide scale sewage of steel industry.
3. Suitable to pump clean water or fluids have close characters with water;The pumping temperature is below 80ºC, solid diameter below 10 mm, fluid density below 15%.
