Butyl diaphragms and valves are biocompatible and resist many acidic and alkaline chemicals. They resist attack by Phosphate Ester Hydraulic fluids and Ketones. They have excellent weather and sunlight-resistant properties. Butyl is also a good choice for gases because it has very low vapor and gas permeability and applications involving steam sterilization. Temperature range is -20° F to 250° F.
They do not rate well with mineral or petroleum-based fluids and hydrocarbons.
Please Note: Nitrile (Buna-N) diaphragms are fitted to our pumps as standard. Please consult our Chemical Compatibility Charts or contact us regards the selection of other diaphragm materials.
