Santoprene (TPE)

Santoprene is a thermoplastic elastomer (TPE) with very high flex life and good abrasion resistance. It resists many dilute acids and alkalis, water and aqueous solutions and gives particularly long service life in AODD pumps. FDA-compliant versions are available for food applications. Pumps with this check valve are rated for fluid temperatures up to 120 °C (see the data sheet of each version).

Typical fluids

Water, waste water, slurries, dilute acids and alkalis, detergents and food (FDA version).

Typical applications

Water: DI water, distilled water, raw, salt, brackish, waste and condensate water
Waste water & sludge: waste water, filter press feed, sewage sludge, softening and lime sludges, coal and coke slurries
Cosmetics: toothpaste, shampoo, soap, emulsions, detergents
Food & beverages: juices, beer, wort, mash, yeast, must, quark, yoghurt, pudding, chocolate, ketchup
Ceramics: pottery slip, glazes, clay

Limits

Not suitable for mineral oils, aromatic and chlorinated solvents.
