Pump Diaphragms

With 45 years of experience with injection molding diaphragms and PTFE pump components, we have earned the trust of many top OEM for Air Operated Diaphragm (AOD) pump manufacturers. These critical parts are abrasion resistant, offer low friction and wear, and are compatible with a broad range of chemicals in operating temperatures ranging from -240°C to +280°C (-400°F to +536°F). Pump diaphragms can be designed according to working conditions and hardware dimensions in order to reach maximum performance, ensuring long life time performance that precisely matches customer requirements.

Most businesses rely on AOD pumps as they are used as general workhorse devices in transfer applications and in a wide range of industries to handle different materials such as chemicals, crude oil, mining, food, beverage, paints and many more. These pumps use reciprocating diaphragms to pump fluid. Since AOD pumps are essentially leak-free, having only stationary seals between the wetted parts and outside environment, leakage can only occur if the diaphragms fail. Our diaphragm solutions provide a high cycle life due to its PTFE material, lasting longer than diaphragms made from other materials such as elastomers.
