Design peculiarity:

Centrifugal pumps of IHF model are designed on international standards.Pump body is of metal case with fluoroplastic liner inside.Its impeller and pump cover are made by pressing metal insert with fluoroplastic around it.Shaft seal is of the advanced outer -built type of mechanical sealing with corrugated pipe, stationary ring is of ceramic of 99.9% aluminum oxide;moving ring is of F4. They have advantages of good corrosion and wear resistance and tightness.
