1. WL series vertical sewage pump is developed on basis of digestive absorption for advanced technologies on similar products home and abroad;
2. WL series vertical sewage pump is in unique impeller design and reasonable vortex chamber design to allow the pump to have advantages of good pollution discharge performance, no blocking and strong anti-winding capacity, etc.
3. WL series vertical sewage pump includes high-quality bearings. The impeller is balanced strictly to allow the pump to have features of stable operation, low noise and small vibration.
4. WL series vertical sewage pump is widely applied to municipal works, industrial and mining enterprises and conveying and discharge of commercial sewage, slurry, excrement, lime ash an paper pulp, etc. It can be also used as circulating pump and for farm irrigation, etc.
WL series vertical sewage pump has compact structure and is mainly composed of motor, motor support, oil chamber, coupler, transmission shaft, mechanical seal (packing seal), pump body, impeller and base, etc.
1. Class F insulation of motor and enclosure protection class IP54.
2. If the bump body center is higher than the horizontal plane (in the absorption range), a vacuum device may be equipped for the user.
3. All models of pump can be made into explosion proof type.
4. Wear-resisting or anti-corrosion materials shall be used for the flow pass materials.
