The WQ sewage submersible electric pump (hereinafter referred to as the electric pump) complies with the GB/T 24674-2021 standard, and the pump motor is manufactured using advanced technology imported from abroad, which features efficient non-standard design, reliable operation, and low cost. The motor housing is made of high-quality stainless steel material, and the motor is self cooled by water. When the pump is working, the motor part can be exposed to the water surface for long-term operation, avoiding the fatal problem of motor burnout caused by only allowing a small part of the motor to be exposed during the operation of domestic sewage pumps. Unique pump design: The channel impeller has high efficiency and unobstructed characteristics, and the maximum particle passing diameter can reach 100mm.
