DG type multi-stage cut submersible drainage pump

Product overview

DG multi-stage cutting submersible drainage electric pump is mainly composed of three parts: single or three-phase asynchronous motor, lower pump-type structural pump components and sealing. Mechanical seal and skeleton oil seal are used as dynamic seal between pump and motor. The fasten sealing is at the static seal with an “O” shape seal ring. The impeller adopts the semi-open structure, and the pump body is improved based on the spiral centrifugal structure of the flow channel, which has a high passability and does not block the debris. The cutting device of the electric pump is composed of the internal cutting device and external cutting device. The internal cutting device is radial cutting, while the external cutting device is axial cutting, and the axial gap of the external cutting device can be adjusted freely and undifferentiated, so that the electric pump has a crushing effect on cutting both hard debris and soft debris. Therefore, this series of electric pump is especially suitable for the working condition like animal husbandry plant, septic tank and pond, whose medium contain a large number of hair, fiber, rope and other debris.
