Submersible Sewage Pump
Submersible sewage pumps are ideal for pumping sewage and waste. They can be customized in various materials, and feature a simple structure and easy maintenance.
Submersible Sewage Pump
The WQ series sewage and waste water submersible pumps (hereinafter referred to as the electric pumps) consist of a pump, a seal, and an electric motor. They are suitable for the discharge of sewage and waste water in municipal sewage treatment, construction projects, hotels, miners, ponds, dyeing, papermaking, textile and other places. They are ideal equipment for pumping slurry, cement slurry, domestic wastewater, sewage, feces and urine, and solid particles containing fibers and paper debris.
The electric motor is located at the top of the electric pump, and it is divided into single-phase and three-phase asynchronous motors. A double-end face mechanical seal is adopted between the pump and the electric motor, and an “O” type oil-resistant rubber sealing ring is used for static sealing at each fixed stopper sealing point.
This series of electric pumps have the characteristics of compact structure, large flow rate, high efficiency, and convenient use. The mechanical seals at key parts are made of hard alloy and high-quality silicon carbide, and the rotor shaft of the electric pump is made of 45# steel through quenching treatment. Corrosive media can be selected from stainless steel materials to ensure the reliable mechanical strength of the shaft and effectively improve the wear resistance and corrosion resistance of the shaft. It is also convenient for the maintenance and disassembly of the impeller.
The entire series can be optionally equipped with an automatic coupling device. When the pump needs maintenance or repair, it can be easily lifted, disengaged, and engaged by the chain screw. Engineering personnel do not need to enter the water to disassemble, effectively improving the convenience and safety of the operation.
