WQ (QW)Series High Efficiency Non-block Sewage Pumps
Product Catalog:SEWAGE PUMP SERIES
QW type submersible non-clog sewage pump is made up of motor and pump, they are separated through oil isolation room and mechanical seal, it is short in length that motor and pump share the same axle (rotor), the structure is compact.
 

Product parameters

Flow Rate Range: 8-2600m3/h
Head Range: 7-60m
Operation Temperature: -15℃-60℃
Matched Power: 0.75-280KW
Working Pressure: ≤1.6MPa
Flow-through Material: Cast Iron, Stainless Steel

Features 1. Adopt big flow non-clog design, improving the ability to pass dirty things greatly.
2. The design is rational, with high efficiency, and the energy-saving is remarkable.
3. Adopts in series mechanical seal, the material is the wear-resisting carbonization tungsten, featuring being durable, wear-resisting, can running for more than 8000 hours continuously safely.
4. The structure of the pump is compact, small, may move conveniently, installation is simple and convenient, it is submerged into the water, no need to build the pump house, reduce construction cost greatly.
5. There is probe in the oil room of the pump, if the pump side mechanical seal is damaged and water enter into the oil room, it would give off signals so as to protect the pump.
6. Can be equipped with control box according to the needs of user, it will protect the pump from electric leakage, water leakage, overload and overheated, etc. guarantee the pump operates reliably and safely.
7. The automatic coupling installation system of one pair of guides, it is convenient for the installation and maintenance of the pump, no need to enter into the sewage hole.
8. The float switch, according to the necessary water level changing. Control the start and stop of the pump automatically, no people needed to guard it.
9. According to use situation, the motor can adopt water jacket the-third party circulation cooling system type, which can guarantee the safe operation of the pump under the anhydrous (dry type) state.
10. Installation can be fixed automatic coupling installation or non-fixed portable installation, which can satisfy different occasions.
MainApplication

 This series of pumps are mainly used in municipal engineering,buildings,industrial sewage discharge,sewage treatment in environmental protection,factories and mines to deliver sewage,wastewater and rainwater etc,containing solid substances and long fibre.Stainless steel may also be used to deliver corrosive medium.

 Working Conditions

1. Temperature 0f medium not exceeding 60℃,gravity 1.0~1.3kg/dm3,and PH value between 5~9.
2. For pump without internal gravity flow circulation cooling system,its motor will be revealed above liquid surface by less than 1/3.
3. Generally, pumps shall be working within the range of head to protect the motor from overloading.To work at the full head.please specify when placing an order for our convenience in manufacturing.
4. The current Of motor during the process of operation shall not exceed the rated current of motor.
