WQD Series Cutting Sewage Submersible Pump High Flow Pump 50Hz

. New WQD –Italian designed submersible sewage pump adopts anti-blockage hydraulic tech. with strong particle passing capacity.
. Outlet can be connected with flange PN6 or PN10.
. It’s installed with special 0-ring seal between the outlet and the flange, which can enhance waterproof.
. And our pump use the double O-ring seals on the top cover and the barrel to enhance waterproof.

Electric WQD Series Large Flow Submersible Sewage Pump

WQD type submersible sewage pump adopts anti blockage hydraulic design or cutting function design, big particle passing ability.Especially JYWQ series pump with automatic mixing device is based on the ordinary type sewage pump, the device rotates with the motor shaft , mixing a very strong force, stirring the sediments of the sewage tank into suspension,Sucking into pump and Flow ,improve the anti blocking, sewage capacity of pump, disposable completion of drainage, sewage, saving operation cost,is obviously advanced and practical environmental protection product.

Big Flow Submersible Pump WQD Series Characterisics

The impeller has adopted unique single blade or double blade structure,greatly increased the filth passing ability.The fiber material which 5 times of the pump diameter and the solid grain which 50％ of the pump diameter can be easily passed through.

Mechanical seal is double mechanical seal made of corrosion resistant tungsten carbide as a hard alloy,featuring long –use and wear –resistance.

The whole structure compact,small volume,low noise,remarkable energy saving,convenient inspection,no need to build pump house,just work in the submersible water,greatly reduce the project cost.

As requested by the user,an anti-jamming water leakage detecting transducer with high accuracy is available to be set in the oil chamber as well as to recess a thermal sensor in the stator windings as require by the user.In case the mechanical sealing damaged,water coming into the sealing oil chamber ,or the motor getting hot by over-load,the transducer and the thermal sensor can absolutely protect the pump motor.

As the user request,the automatic safety –protection controlling cabinet can be arranged to absolutely protect the pump from water leakage,electric leakage,over –load and over-temperature,enhancing the product safety and reliability.

The float –ball switch can automatically control the pump to start or stop according to the request liquid position change,no need special person to take care,it is most convenient to use. As requested by the user,a double guide –rail automatic coupling mounting system can be equipped,bringing great convenient to the mounting and maintenance and allowing the maintenance personnel to maintain the machine without walking into the sewage pit.

Can provide two kinds of mounting type to satisfy the different usage,i.e.Fixing automatic coupling mounting system and the moving free mounting system.
