NASH Polyisoprene Lining for vacuum pumps reconditioning

This feature provides protection against corrosive and erosive matter, decreases power consumption caused by internal wear and reduce maintenance and repair costs.

The polyisoprene lining is vulcanized, not glued, to the pump casing. The polyisoprene lining binds the wetted surface better than cladding, and the bond occurs over the entire surface of the part. The chemical bond to the iron housing is so strong that a tensile test reults in the polyisoprene material failing, but the bond remaining intact.

The liner is resistant against many acids, alkalis, salt solution, and erosive particles in the liquid ring. Should any damage occur, the liner is field repairable.
