Benefits

Reliable sealing ensured by one single sealing element (the diaphragm), which provides hermetic sealing to atmosphere and absolutely tight shut-off. The specially enclosed diaphragm ensures long service life and high operating reliability.
Increased functional reliability of the diaphragm thanks to balanced diaphragm suspension
Maintenance-free as all moving parts are separated from the fluid by the diaphragm.
