Handling corrosive chemical fluids presents significant challenges for industrial pump systems, as standard materials degrade rapidly when exposed to aggressive media, leading to premature component failure, leakage risks, and frequent maintenance cycles. The MPH series magnetic drive pump is engineered specifically to address these harsh service conditions through carefully selected high-corrosion-resistance materials.
All primary wetted components are manufactured from glass fiber reinforced polypropylene, a material with broad chemical compatibility and excellent resistance to most acids, alkalis, and salt solutions. Critical rotating and wear components—including the pump shaft, mating ring, and thrust ring—are fabricated from high-purity alumina ceramic, which provides exceptional hardness, wear resistance, and chemical inertness.
The shaft bushing and primary rotating ring use carbon-fiber filled polytetrafluoroethylene (PTFE), a material that combines low friction characteristics with outstanding corrosion resistance. This material pairing ensures stable, low-wear operation even when pumping chemically aggressive fluids, extending the service interval of the pump.
Sealing elements are available in FKM fluororubber for general chemical service and EPDM for compatibility with specific fluid types. Combined with the seal-less magnetic drive architecture, these material choices create a fully contained fluid path that prevents hazardous or corrosive media from escaping into the workplace or environment.
With temperature ratings up to 80°C for standard GFRPP construction and 100°C for PVDF construction, the pump series supports a wide range of chemical process temperatures. This robust corrosion performance makes the MPH series a reliable choice for chemical manufacturing, metal finishing, semiconductor wet processing, and other applications where fluid compatibility and leak prevention are critical operational priorities.
