Product Features of WQN Internal Circulation Pumps with Cooling System

In the aspect of structure, the cooling system uses the filled self-circulation anti-freezing cooling liquid, and makes it pass through the closed channel and flow to the ingenious heat exchanger to carry out the heat exchange with the liquid delivered in the volute casing. After heat dissipation, the cooling liquid enters the special circulation channel through the auxiliary impeller and reaches the motor enclosure, so as to carry out the circulation cooling for the submersible motor. The fast circulation speed of cooling liquid, large flow and excellent heat dissipation effect thoroughly solve the problem that the cooling channel is obstructed, the motor temperature is too high and even the motor is damaged as WQ series submersible motor for submersible sewage pumps adopts the sewage self-cooling method.


The product has high technical content, used for submersible and dry-type purposes.When the dry-type installation is adopted, there is no need of configuring the cooling & circulation water system. The application scope is greatly expanded.


It is very convenient for cooling system disassembling and cooling liquid filling & replacement There is no need of removing the motor & water pump. The related personnel only need to unscrew the bolt on the pressing plate. The self-circulation cooling liquid used for WQN internal circulation & closed cooling system is nontoxic and water-soluble, which overcomes the problem that WQ submersible sewage pump's oil leakage phenomenon arisen from seal failure causes the secondary pollution for the environment. Especially, this will bring a significant effect to drainage pump stations and running water plants in the surrounding area of sewage treatment plants.


This pump is widely used for various sewage treatment circumstances. When the sludge with a great deal of liquid is delivered, the cooling channel's clog-proof effect is the most obvious.
