What are rubber diaphragm?
Rubber diaphragms offer a simple yet effective sealing solution for pumps, valves and many other control devices across a wide range of industrial applications. SWKS has many years of experience in the design, development and manufacture of high-quality rubber diaphragms and custom moulded diaphragms.
What a rubber diaphragm is first of all?
A rubber diaphragm is a flexible membrane that’s usually circular in shape and anchored around the edges. The main function of a diaphragm is to act as a seal between two chambers. Rubber diaphragms come in a huge variety of shapes and sizes, as well as custom moulded diaphragm configurations. For instance, we can provide PTFE-bonded rubber diaphragms for use with aggressive chemicals, fabric reinforced rubber diaphragms for added durability, or high-tolerance thin walled rubber diaphragms.
How do rubber diaphragms work?
Pressure differences cause a rubber diaphragm to move up into a chamber or down into another chamber, enabling a degree of motion between a stationary and a moving part. Due to their low permeability to fluids and gases, rubber diaphragms maintain media separation on either side of the diaphragm. They also ensure a consistent pressure differential between the media and can provide gasket functionality in the flange of an instrument.
