The GEMÜ code 28 diaphragm is a one-piece, sulphur-cured EPDM diaphragm developed for use in drinking water and water treatment applications. There is no fabric layer to ensure compliance with the applicable valid drinking water regulations. The diaphragm displays reduced setting behaviour and signs of wear, which enables high switching cycles and therefore an increased service life.
- Low signs of wear and optimized setting behaviour
- Greatly reduced adhesive behaviour (no adhesion on the valve seat) of the diaphragm
- Simple and defined mounting thanks to the threaded pin that is vulcanised in place with integrated screw-in stop
- Approvals according to Belgaqua Hydrocheck & UBA-ELL
