The QDX series submersible electric pump (hereinafter referred to as the pump) consists of three components: the pump unit, the sealing system, and the electric motor. A built-in protection device is equipped in the pump.
The electric motor, located at the upper part of the pump, is a single-phase or three-phase asynchronous motor. The pump unit, situated under the motor, adopts a centrifugal impeller and volute structure. A double-face mechanical seal is applied between the pump unit and the motor. All fixed spigot seals use O-shaped nitrile rubber sealing rings for static sealing.
