WQ type submersible sewage pump is made up of motor and pump, which
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.
WQ Centrifugal Sewage Water Submersible Pump Structure Features
1. Signal line: for motor power above 11kw, we suggest pump
equipped with control box, which would protect the pump fully from
leakage, phase reversal, short circuit, overheated, overload, etc..
2. Motor stator: its insulation is B grade or F grade.
3. Water leakage probe. This component is installed in the oil
room, if the mechanical seal was damaged, and water enters into the
oil room, it will send out the signal to the control system so as
to stop the pump.
4. Mechanical seal: Adopting in-series seal, the material is the
wear-resisting carbonization tungsten, featuring being reliable,
wear-resisting, longer life, etc.
5. Impeller: have better handling capacity, can reduce the trouble
of jamming and twisting of big fiber rubbish, etc.
6. Pump body: harmonize with impeller, ensure the pump has high
efficiency.
7. Seal rings: Installed at the mouth place of pump body, can
change the sealed ring after long time operating, so as to ensure
the pump runs with the best efficiency.
WQ Centrifugal Sewage Submersible Pump Advantages
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, long service life.
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
circulation cooling system type, which can guarantee the safe
operation of the pump under the dry state.
10. Installation can be fixed automatic coupling installation or
non-fixed portable installation, which can satisfy different
occasions.
WQ Waste Submersible Pump Working Conditions
1. Temperature 0f medium not exceeding 60°C,gravity
1.0~1.3kg/dm3,and PH value between 5~9.
2. For pump without internal gravity flow circulation cooling
system,its motor 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 value.
WQ Centrifugal Sewage Pumps Applications
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
fiber. Stainless steel type may also be used to deliver corrosive
medium.
