Diaphragm Seal Monitoring

Double Diaphragm Seals and Break Monitoring – A Safety–Net for Pharma–Production

How double–diaphragm and diaphragm break monitoring technology provides safety for pharmaceutical production plants — By using diaphragm seals, pressure measuring instruments can be adapted to even the harshest of process conditions. Here, a diaphragm separates the measuring instrument from the process medium and transmits the pressure hydraulically. A double-diaphragm design offers a solution for pharmaceutical applications, where the process must remain sealed under all circumstances and the hazard risk for people and the environment must be minimised.

Rubber Seals made from Bio–Based EPDM

Seals specialist Freudenberg uses Lanxess' bio-based Keltan Eco EPDM rubber to produce rubber seals in North America. Keltan Eco EPDM ( ethylene-propylene-diene monomer) rubber contains up to 70 percent of ethylene obtained from sugarcane, and has an impressive set of properties that is in no way inferior to that of “conventional” EPDM.
