Slurry Pump Spare parts Information
Volute liner seal is the rubber seal installed on a metal lined slurry pump between the volute liner and the frame plate to keep the fluid from leaking. All volute liner seals will be seen only on metal slurry pumps.
Slurry pump volute seals are normally made in rubber. Volute Liner Seal material alternatives: S01-EPDM Rubber, a kind of synthetic elastomer and S10, a type of nitrile synthetic rubber.
There is only one volute seal in small pumps where the volute liner and throat bush are in one solid casting.
The slurry pump volute seals are also available to suit: AH pumps, L pumps, M pumps, HH pumps, G and GH pumps
