| WL and LW vertical sewage pumps are mainly composed of shaft, bearing frame, pump cover, impeller, pump seat, motor bracket, motor and other components. The pump is a vertical single-stage single suction vortex shell pump, and the impeller adopts a dual channel structure, which can effectively pass through fiber materials with a diameter of 5 times the pump diameter and solid particles with a diameter of 50% of the diameter. The product complies with the JB/T6535-92 "Technical Conditions for Centrifugal Sewage Pumps" standard. |
1. Safe and reliable, reducing maintenance costs: The balanced rotor components and reasonable bearing arrangement effectively balance the radial and axial forces of the pump, ensuring long-term stable operation of the unit with low vibration and noise.
2. Strong flow capacity: Smooth large flow channel and special impeller anti blocking design ensure efficient and unobstructed pump operation.
3. Double sealing and double protection: The dual machine seals are configured in series to truly achieve dual protection and ensure the safety of the motor. |
