Rubber Diaphragms

Rubber Diaphragms

Molded Elastomeric rubber diaphragms are tough, versatile dynamic seals that eliminate virtually all of the limitations associated with other sealing methods like U-cups, O-rings, metal bellows and flat die-cut diaphragms. They can withstand pressures to 6,000 psi (4.137 bar) over a temperature range from -76°F to 626°F (-60°C to 330°C). We currently manufacture diaphragms ranging in size from 0.1969″ to 29.1339″ (5 mm to 740 mm).

Inseal is dedicated to providing rubber diaphragm seals that enhance the performance and appeal of your product at a price point that helps you compete. Our engineering department stands ready to provide product design support that is both timely and comprehensive.

Rubber Diaphragms

Diaphragm seals are manufactured from standard and quality rubber materials to highly advance compounds for chemical compatibility. A rubber diaphragm seal is required to provide flexibility and memory for various fluid and pneumatics applications. It has been designed and developed for individual pump companies to use in their own pumps and valves. Since it is manufactured as One-piece, it avoids the possibility of leakage and also prevents abrasive particulate material getting between the PTFE and rubber.

Inseal International is one of the esteem manufacturers and exporters in Mumbai, India. We supply a wide range of moulded and lined diaphragms which are used in all kinds of valves, pumps and actuators used in critical corrosive applications. The rubber used with PTFE linings are Neoprene, EPDM and Butyle.

Our product sizes range from 12mm to 900mm diameter in various shapes as per client’s requirements.
