These centrifugal pumps are interchangeable with IH series pumps. According to customer requirements, the IHF-1 series pumps feature a plastic lining structure with flow passage made from fluoroplastic. After sintering, the fluoroplastic are closely attached to the steel to ensure a flawless, efficient operation. The mechanical seal use alumina ceramics, SiC, nickel base alloys, cobalt base alloys and tetrafluoroethylene, ensuring these pumps have the same strength as metal pumps, but are also resistant to various chemicals, high temperatures, high pressures and highly corrosive materials. They are economical choices for applications in almost every industry and have a long service life.
