Rubber Diaphragm
Diaphragms are counted as the most versatile element across all sealing needs, serving as reliable but flexible separating wall between two component spaces.
It has a wide – application across industries like Fluid Handling, Power Generation, Aerospace, Chemical & Process Industry, Irrigation, Automotive Tier, Foods & Beverage that use pumps & compressors, actuators, water reservoirs, hydro – accumulators, valves, regulators and any other such industrial components as a part of their operations value chain.
| Main application | Pump valve industry, Pressure regulation / Control valve, Pneumatic Actuators |
| Size | 8mm to 840 mm diameter |
| Materials | NBR, EPDM, FKM, FVMQ,, HNBR, Silicone, Neoprene and PTFE – Reinforced and Non-reinforced |
| Technical | Pressure : Upto 60 bar Temperature : – 60 ° C / + 200 ° C (depending on material) |
Rubber diaphragms play a critical role in creating reliable seals between chambers while allowing controlled flexibility and movement. These membranes are used to prevent leakage, reduce friction, and maintain consistent performance across mechanical, pneumatic, and hydraulic systems. As experienced rubber diaphragm manufacturers, we focus on precision, durability, and long-term reliability for complex industrial needs.
