Application

Q(D) type dry submersible electric pump (hereinafter referred to as electric pump) consists of three parts: water pump, seal and motor. The water pump is located at the upper part of the electric pump and is a multi-stage centrifugal impeller with radial guide vane structure; the motor is located at the lower part of the electric pump and is a single-phase or three-phase asynchronous motor structure; a double-end mechanical seal is used between the water pump and the motor, and an "O" type oil-resistant rubber seal is used at each fixed stop seal.
