KIPFLEX Rubber Diaphragms

KIPFLEX Rubber Diaphragms / PTFE Diaphragms

Polytetrafluoroethylene-PTFE (Teflon) is an engineering thermoplastic resin that is practically resistant to all fluids. Of all our diaphragm materials, it is the most chemically resistant., PTFE can be used with media reaching very high temperatures up to 300° C. PTFE is popularly known as Teflon which is a Tradename of Dupont.

We specialise in PTFE lined Rubber Diaphragms (0.25mm, 0.5mm, 1.00mm lining thickness) as well as Pure PTFE Rigid (upto 3mm thickness) Diaphragms for all kind of Valves, pumps and actuators used in critical corrosive applications. The Rubber used with PTFE Linings are Neoprene, EPDM, Butyl & Hypalon.

Our PTFE Lined Diaphragms are made from size ranging from 12mm to 600mm Diameter in various shapes as per clients’ requirement. Our Diaphragms have been tested upto 6kg/cm2 and operated upto a 1000 cycles. These diaphragms are not suitable for vacuum service and high pressures.

We design, develop, prototype PTFE Diaphragms as per your requirements/service conditions.
