Product Introduction:

LW type upright unobstructed sewage pump

This series of sewage pumps adopts impeller structure and mechanical seal, which can effectively transport solid matter and long fibers. Compared with traditional impellers, the impeller of the sewage lift pump adopts a single channel or double channel form, which is similar to a curved pipe with the same cross-sectional size and has very good flow capacity. Coupled with a reasonable volute chamber, the pump has high efficiency and the impeller has undergone dynamic and static balance tests, making the pump operate without vibration.

Product features:

1. The use of a single or double blade impeller structure greatly improves the ability of pollutants to pass through, effectively passing through 5 times the fiber material of the pump diameter and solid particles with a diameter of about 50% of the pump diameter.
2. The mechanical seal adopts hard and corrosion-resistant titanium tungsten material, which can ensure the safe and continuous operation of the pump for more than 8000 hours.
3. The overall structure is compact, the volume is small, the noise is low, the energy-saving effect is significant, the maintenance is convenient, and there is no need to build a pump room. It can work underwater, greatly reducing the project cost.
4. The vertical sewage pump has strong overcurrent capacity: a smooth large flow channel and a special impeller anti blocking design ensure efficient and unobstructed operation of the pump.
5. Vertical sewage pump with dual sealing and dual protection: The dual mechanical seals are connected in series to truly achieve dual protection and ensure motor safety.
