Opar-Mi WQ Series submersible sewage pump is mainly used for municipal works, industrial buildings ,hotels, hospitals, civil air defense, mines etc. Trades to drain off the sewage, waste water, rainwater and living water in cities containing solid grains and various long fabrics.
Bearings: We use imported SKF bearings or NTN bearings.
Cooling: the built-in cooling system ensures proper operation of the pump, while the motor remains either on the surface or under the liquid level. When the pump body circulates the liquid to the cooling cylinder and the casing, it utilizes heat generated by the motor. When an external cooling is needed, the cooling sleeve can be separated from the pump body and connected using a separate cooling system.
Mechanical seal: We use German standard mechanical seals, and the two mechanical seals series work independently of each other. The pump side material is tungsten carbide, while the motor side is graphite or carborundum.
Oil chamber: oil can lubricate and cool the mechanical seal, as well as prevent liquid from penetrating into the motor in order to prevent safety failures
Float switch: when the mechanical seal of the motor side leaks, the liquid enters the float switch chamber, and when the liquid reaches a certain height, the float switch will send out the alarm signal and stop the pump.
