Updates to the design of magnetic pumps

We would like to inform you about a minor design update of the QHX series magnetic pumps manufactured from PPH, PVDF, and CFRETE materials. The overall dimensions and connection sizes of the pumps remain unchanged, which will not create any issues for our customers when replacing the pump in the future. Details are provided below.

The QHX front cover has been upgraded from a “threaded + flanged design” to an integrated flanged structure manufactured by injection molding. Please find the update photos attached for reference. The inlet and outlet flanges have been upgraded from a bolted connection design to a one-piece molded structure, eliminating any risk of leakage at the flange connection points.

This update does not affect the performance or installation dimensions. It only improves sealing reliability and structural strength.

Conclusion: The purpose of this update is to optimize the product design, improve reliability, minimize the risk of leakage, and reduce maintenance costs.
