Elastomeric Diaphragms

In 1950, Bellofram introduced the original rolling diaphragm for a wide variety of industries and applications. Since that time one billion diaphragms have been used successfully throughout the world.

Engineering plays a critical role at every level in our manufacturing cycle. From design, tooling completion, to integrating procedures into production processes, is one aspect of total quality commitment.

The performance of the rolling diaphragm depends, in large part, on the preparation of materials. Raw materials are accepted after close scrutiny and absolute conformity to tight specifications. Elastomers are compounded with extreme care, then coded to ensure complete batch traceability. Reinforcing fabrics are woven or knitted to specifications developed exclusively by Bellofram. Meticulous preforming practices help to ensure a permanent, high strength bond between elastomer and fabric. Click here for more information.
