PTFE (5)

Versamatic fluid repair kits with PTFE diaphragms – identified by 5 at the diaphragm position of the Versamatic part number.

PTFE (polytetrafluoroethylene) offers almost universal chemical resistance – to concentrated acids and alkalis as well as solvents, fuels and oxidisers. In air-operated diaphragm pumps PTFE is used as a one-piece FUSION diaphragm or as a 2-piece diaphragm with an elastomer back-up, because PTFE itself has little elasticity.

Always replace diaphragms, check valves and seals together: a complete kit restores full performance and prevents consequential damage from diaphragm failure.
