Small EPDM Gas / Pressure Diaphragm Rubber Excellent Fatigue Resistance
Description :
We manufacture Rubber diaphragms for applications like Pumps,
Actuators, LPG Valves, CNG Valves, Wax actuators, Thermal
Actuators, Gas Diaphragm and Pressure Diaphragm. Our diaphragms are
both reinforced and non-reinforced. We have various apporovals and
have supplied parts in thousands per week to Kosan Industries
for Gas Regulator. We maintain dimensional tolerance of
Precision Actuator Diaphragm to 0.02mm (+/- 0.001 inches).
Designing and Manufacturing a Rubber Diaphragm is a science itself and there are a lot of factors involved to get the right fit; for example design, raw material, pressure, medium in contact etc. Hence, it is best to use expertise right from the development stage, hence improving product efficiency and cost. We have helped numerous clients with their designing and provided them with customized application based solutions.
Contact us for more details on parts and approved materials in NBR, HNBR, FKM (FKM). Our designing department equipped with state of the art facilities including a Video Measurement System will make sure that your needs are met with utmost accuracy with least amount of lead time.
