QW type submersible Sewage Pump is developed based on imported advanced technology abroad.It has the advantages of high efficiency,not easy to enlace,no clogging,auto-coupling and auto-control
The advantages of QW pump are its small volume,compact structure and high efficiency,with products more than 15kW.It can detect the water leakage,overheat,overload protection.And as the requirements of user,an auto-protection control cabinet which has liquid level control shall be equipped.
Installation type of QW type pump has auto-coupling installation and movable installation.
QWN type submersible sewage pump is developed based on QW type pump,absorbing advanced technology abroad.

Application Area
QW type pump is mainly used in urban construction,industry,hospital,building,hotel,restaurant and so on.It is used to transport silt,urban sewage containing solid granule and long fiber.
QWN type pump is mainly applied in municipal engineering,steel plant,power plant,mines and some other wear-resistant sites for discharging sludge and waster water containing solid particles.

Structural Characteristics
QWN type is a kind of submersible sewage pump with mixer/agitator.
QWN type submersible sewage pump has compact structure and is mounted with various kinds of status display and protective device to make its operation safe and reliable.The structure of pump is characterized as follows:
   The unique seal cable design makes it effective to avoid leakage as a result of cable breakage.
   The leakage detector inside the wiring chamber can make alarm noises if there is leakage inside,and then the control system begins to protect the pump.
   The insulation class for the rotor of the motor is F.Every phase is quipped with overheat and overload protective components.
   Stainless steel is used for the rolling motor shaft.The dynamic balance of rotor is carried out to make pump run more smoothly.
   The circulation cooling system cools down the motor rotor,which improves the motor's working condition and then the pump is allowed to be operated in case that the pump exposes outside the water surface or the pump runs dry.(Not in the case of type of pump under 18.5kW).
   Two seal inspections are set up so that alarm noises can be made if any seal leakage happens.
   Carborundum or carborundum double end face is used in mechanical seal to ensure that the pump can operate safely and reliably for a long period of time.
   The flow impeller design can make pump have powerful flow,block-proof and high efficiency,and it can also make the pump in full head so that it is convenient to make adjustment on capacity and select the right pump type.
