SISTO-C Elastomer diaphragms
SISTO soft elastomers are made from an EPDM rubber which has been designed to withstand an operating temperature of up to 140°C. The diaphragm material corresponds to FDA requirements, EU1935 and has been tested and certified in accordance with USP guidelines.
The diaphragms are well suited for use in “cold applications” such as in WFI systems, and thanks to their high ozone resistance they have proven extremely successful in CIP applications with all types of standard cleaning media. These EPDM diaphragms are also ideal for sterile steam applications.
A piece of fabric integrated into the EPDM rubber enables the diaphragm to be used under vacuum. The diaphragms can easily handle solids-loaden fluids and have a long service life.
