PTFE

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. Pumps with this check valve are rated for fluid temperatures up to 175 °C (see the data sheet of each version).

Typical fluids

Aggressive chemicals, solvents, paints, high-purity fluids and any application where chemical compatibility is uncertain.

Typical applications

Acids: mineral and organic acids
Solvents: aromatic and aliphatic solvents, ketones, aldehydes, esters, chlorinated hydrocarbons, de-icers
Coatings: emulsions, latex, pigments, resins, solvents, thinners
Electroplating: aggressive acids and salts, residual sludges, waste water, neutralisation, caustic soda, ferric chloride
Pharma: liquids, creams and additives

Limits

With highly abrasive slurries PTFE wears faster than Santoprene or Neoprene – worth comparing.
