Types of Diaphragms

Valve (WEIR Type) Diaphragms

Valve diaphragms are sturdy and flexible seals that allow for opening, closing, and regulating fluid transfer in control valves. The diaphragm regulates the flow of fluids, which are normally very viscous in nature.

Pump (AODD) Diaphragms

Along with diaphragms for valves, Western Rubbers possesses the capabilities to manufacture pump diaphragms too. Air operated double diaphragm (AODD) pumps are used in a very wide range of industries, from petrochemicals to mining to food processing.

Rolling (Actuator) Diaphragms

Rolling diaphragms manufactured by Western Rubbers, are flexible fluid control devices. They find critical application in industries such as chemical processing, automotive, food and beverages, aerospace, and medical.
