WQP series submersible sewage pump with stainless steel anti-clogging crowd said hydraulic component design, greatly improving the dirt through the ability to effectively pump diameter by 5 times the fiber material and the diameter of the pump diameter of about 50% of the solid particles. (2) rational design, reasonable auxiliary motor, high efficiency, energy saving effect is remarkable. 3 tandem mechanical seal is double sealed, made of hard wear-resistant tungsten carbide, with a durable, wear characteristics, can pump more than 8,000 hours continuous operation safety. 4 pump compact, small size, easy to move, easy to install, no need to build the pumping station, diving into the water to work, greatly reducing the project cost. 5 room has a water pump oil probe, when the pump side of the mechanical seal is damaged, the water into the oil chamber, the probe signal occurs, the implementation of protection of the pump. 6 according to user needs with a fully automatic safety protection control cabinet, the pump leaks, leakage, overload and over temperature monitoring, to ensure safe and reliable pump operation. 7 double rail automatic coupling installation system, the installation of the pump installation, repair, has brought great convenience, but this may not have access to the sump. 8 float switch according to the desired water level changes. Automatic control of pump stop start, without special care. 9 In the context of using the lift to run the motor is not overloaded. 10 where the motor can be used depending on water jacket cooling system outside third party, to ensure the pump in water (dry) state of safe operation. 11 installation of automatic coupling installation of fixed and mobile installation of two kinds of freedom, can be used to meet different occasions.
