Membranes for expansion vessel

Semperit produces and develops customer-specific full and half membranes for heating and drinking water circuits. The membrane separates the gas from the water side, thus guaranteeing the functioning of the system.

Semperit offers the following rubber compounds adapted to the individual application case (SBR, IIR, CIIR and EPDM as well as NBR). The Semperit membranes fulfil the common standards of DIN4807 and EN13831 as well as additional customer-specific requirements.

We offer products certified for drinking water according to UBA, W270, ACS and WRAS and if required other national certificates.
