Product Overview:
The motor stator of submersible sewage pumps WQ(D) series (hereafter referred as electric pump) lies in the upper part of electric pumps, single phase or three-phase asynchronous. The hydraulic part seated under the motor stator, using a large channel of hydraulic design. The dynamic seals between the hydraulic part and motor are double mechanical seal and oil seal. The static seals are oil resistant rubber "O" rings.
This product has passed CE certification with 1 year quality warranty.
