Product Overview
The QDX(T)/QX(T) Submersible Sewage Pump consists of three main components: the pump, sealing system, and motor. The pump is equipped with internal protection devices. The motor is located at the top of the unit and is available in single-phase or three-phase asynchronous types. The pump section is located at the bottom and is equipped with a centrifugal impeller with a volute casing. A double-end mechanical seal is used between the pump and motor, and all fixed connections are sealed with oil-resistant “O” ring gaskets to ensure reliable static sealing.
