Structural diagram of Fengqiu WQ series non-clogging submersible sewage pumps

Thread Content

1. A unique waterproof cable design that effectively prevents leaks caused by cable rupture. 2. The leak detection probe located in the wiring chamber can issue an alarm signal in case of a leak there, allowing the control system to protect the pump. 3. The motor stator features F-class insulation, and each phase is equipped with overheat and overload protection components. 4. The motor shaft is made of stainless steel, and the rotor undergoes dynamic balance testing to ensure smoother operation of the pump. 5. Set up a secondary seal monitoring system to trigger an alarm at the slightest leakage in either seal. The leak detection probe located in the wiring chamber can issue an alarm signal when a leak occurs there, allowing the control system to protect the pump. 6. Sealing material: (motor side) graphite/silicon carbide; (impeller side) bismuth carbide/silicon carbide. It offers excellent resistance to high temperatures, impacts, and wear, as well as a long service life. It ensures the long-term safe and reliable operation of the pump. 7. The channel-type impeller design not only endows the pump with advantages such as high flow capacity, resistance to clogging, and high efficiency, but also provides it with a full head characteristic, thereby facilitating flow regulation and pump selection.
