Rubber Diaphragms

Listing ID #393710

Avail from us the Rubber Diaphragms of premium grade quality. The Rubber Diaphragms, we supply, are made as per international standards and are known for their excellent service life. 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 and for those applications that require extremely high-strength. All types of elastomers, such as, Nitrile, EPDM, Fluorocarbon, Neoprene, Silicone, Fluorosilicone, can be used in the fabric-reinforced diaphragms. Many diaphragm applications require that the rolling diaphragms be coated with rubber on both sides, commonly referred to as "double-coat" diaphragms. This type of rolling diaphragm is typically required when the application sees pressure on both sides of the diaphragm in two ways: First, by utilizing our proprietary double-coat molding process, we are able to provide double-coat diaphragms directly from rubber and fabric. Second, by developing and maintaining an inventory of standard "coated-fabrics" that is, fabric that is coated on both sides by a sub-contractor using a variety of materials. The selection of the proper double-coat process and materials requires an understanding of both the rubber and fabric used in its fabrication, as well as the overall geometry of the rolling diaphragm.
