Rubber diaphragms are used when a flexible component needs to move or respond to changes in pressure without allowing the media on either side to mix. For example, the diaphragm can bend or shift when the pressure changes and is therefore used in valves, pumps, regulators, and other equipment where movement and sealing must be combined.
The design has a significant impact on performance. The thickness, diameter, mounting, and the range of motion allowed for the diaphragm must be adapted to the design and the loads encountered during operation.
The medium decides the materialThe Right Material for Rubber Diaphragms
At Cabseal, we manufacture rubber diaphragms made of EPDM, NBR, CR, SBR, silicone, and Viton®. The choice of material is primarily determined by the medium with which the diaphragm comes into contact, as well as requirements for temperature, chemical resistance, and flexibility.
For example, NBR may be appropriate for contact with oils, while EPDM is used in many applications involving water. Silicone and Viton® can be alternatives when temperature places higher demands on the material.

Rubber Diaphragms Based on Design and Function
A rubber diaphragm must be designed to accommodate the movement and pressure differential to which it is subjected. We can manufacture diaphragms based on drawings or existing samples and assist with material selection based on the intended application.
As part of our range of gaskets and seals, we can also help you find a solution that suits your application. Contact us at Cabseal, and we’ll help you find the right product for your needs!
