Rubber diaphragms
About
Rubber diaphragms are flexible rubber membranes typically made from elastomeric materials like rubber or synthetic polymers that resists leakages & friction between two chambers by creating a seal. It is engineered to perform specific functions such as sealing actuation, pressure regulation or vibration isolation.
As leading rubber diaphragm manufacturers, Harkesh Rubber specialises in reinforced and non-reinforced type diaphragms and are supplying to some of the major OEM’s across the globe.The development of customized solutions for special applications is our passion. For more than 2 decades we have been developing tailor-made solutions in close collaboration with our customers, for challenging fields of application that simply require more than a standardized valve product. This has resulted in countless variations. We have developed diaphragms for series production, and can also manufacture in small batches for selected applications.
