WQE Submersible Sewage Pump

Product Introduction

The WQE series submersible sewage pump is composed of three main components: the water pump, the seal, and the motor. The motor is located at the upper part and is available in both single-phase and three-phase asynchronous electric motors.
A double-end mechanical seal is used between the water pump and the motor, with each fixed stop seal employing an O-ring oil-resistant rubber seal ring for static sealing. Key components of the mechanical seal are made of hard alloy and high-quality silicon carbide. The shaft is made of 45# steel or stainless steel to ensure reliable mechanical strength, wear resistance, and corrosion resistance.
For high-power sewage pumps, the stator embeds a thermal control switch. By default it is set in a “normally closed” state at room temperature, and it opens when the stator temperature reaches 125°C.
During wiring, two “motor temperature rise signal lines” are connected in series to the stop button in the control cabinet. A water leakage probe is installed in the oil chamber for water leakage detection. The “oil-water inlet probe signal line” is connected to any one of the power lines and is connected to the leakage circuit breaker. When there is a leakage in the mechanical seal on the pump side, and the oil-water ratio in the oil chamber reaches a certain concentration, the water leakage probe sends an alarm signal and automatically cuts off the power, stopping the pump.
