QHM Series is a high-flow corrosion-resistant magnetic drive pump for acid and alkali circulation duties requiring no shaft seal and no leakage risk. The wetted parts can be configured in PPH, PVDF, and CFRETFE, with model coverage up to 1055 L/min.
It suits corrosive liquid transfer, PCB wet processing, electroplating, surface treatment, and general chemical circulation where stable flow, high corrosion resistance, and service life matter.
