EPDM

EPDM (ethylene propylene diene rubber) is highly resistant to water, hot water, alkalis, many acids, alcohols and ketones and stays flexible at low temperatures. Pumps with this valve seat are rated for fluid temperatures up to 120 °C (see the data sheet of each version).

Typical fluids

Alkalis, dilute acids, alcohols, ketones, glycol and hot water.

Typical applications

Pickling agents: sodium, potassium and magnesium hydroxides and carbonates, lime slurries
Alcohols: methyl, ethyl, isopropyl and higher alcohols
Water: DI water, distilled water, raw, salt, brackish, waste and condensate water
Rubber & latex: natural and synthetic latex, pigments, fillers

Limits

Not suitable for mineral oils, greases and fuels.
