CQ type magnetic drive centrifugal pump is a new type of pump which uses the working principle of permanent magnetic coupling to transfer torque without contact. Zhongcheng pump absorbs the leading horizontal magnetic pump production technology, new material and new process, successfully solves the technical problems of easily damaged parts such as isolation sleeve and impeller of domestic magnetic pump, and makes its performance more perfect beautify. CQ magnetic pump has passed the test of long-term production and continuous operation of users. More and more users are sure that they choose the safest and most reliable pump type. We will continue to provide better service for the majority of users.

The main features of CQ type magnetic drive pump are as follows:

The static seal is used to replace the dynamic seal in the magnetic pump, so that the overflow parts of the pump are completely sealed, which completely solves the problems of running, emitting and dripping that cannot be avoided by other mechanical seals. The horizontal magnetic pump uses corrosion-resistant, high-strength engineering plastics, corundum ceramics, stainless steel as manufacturing materials, so it has good corrosion resistance, and can prevent the transmission medium from pollution.
