Fabric reinforced diaphragm features

May 31, 2018

Fabric-reinforced diaphragms utilize a layer of an engineered fabric material as part of the diaphragm construction. This layer of fabric gives tremendous design flexibility. A very thin-walled diaphragm can withstand high pressures while remaining very flexible and responsive to minor pressure variations.


Fabrics made of polyester, nylon, and silk are commonly used for most applications, with Nomex fabric used for those applications exposed to high-temperature. For those applications that require extremely high-strength, Dia•Com offers our unique Dia•Tuff fabric.

All types of elastomers, such as nitrile, EPDM, fluorocarbon, neoprene, silicone, fluoro silicone, can be used in the fabric-reinforced diaphragms.


Advantages: high work reliability, good revival, long working life. 8 to 10 million movements
