Sealing membrane

stainless steelFEPfoam

The SKUM foam sealing membrane is designed as a wafer thin seal that is easily installed between flanges. Manufactured from corrosion resistant stainless steel, a Teflon FEP membrane seals off the storage tank content from the foam line. Application The foam sealing membrane is intended for use as a check valve. This seals off the tank product from the foam supply line in a subsurface system or as a gas-proof check valve in an over the top foam system. The foam sealing membrane is an integral part of the systems to be added in the PFG subsurface and HSSS semi-subsurface foam units. Features The foam sealing membrance has the following features: Corrosion-resistant construction made from stainless steel and Teflon FEP Installed between DIN and/or ANSI flanges Low opening pressure in flow direction High back pressure resistance in back flow direction Self centre flange ring Teflon FEP membrane is resistant to most chemicals excluding pressurised, heated halogen fluorine compounds and alkali metals Connections The foam sealing membrance fits in pipework flanged according to DIN PH16 and ANSI 150 lb and mm size.
