When pneumatic or hydraulic pistons repeatedly slide inside of cylinders, they rely on fluid power to transmit force. It’s no secret that the total force couldn’t be transmitted without a tight seal. But rough-and-tumble environments and heavy-duty applications can destroy most seals. And when designs require low friction, high cycling, or high fluid pressure, O-rings or die-cut seals simply don’t hold up. In these situations, rolling diaphragms are often the only option. Unfortunately engineers may not know the advantages of rolling diaphragm seals or be aware of precautions to take when designing hydraulic or pneumatic systems that use them.

The demand for medical-use oxygen has recently outpaced supply due to the Covid-19 Pandemic. As a result, the need for portable oxygen concentrators is increasing. DiaCom Corporation is currently working with manufacturers of these crucial machines supplying parts to help get them to hospitals, physicians, and patients faster.
DiaCom Corporation has successfully worked along with the manufacturers of medical ventilators, respirators, and other critical medical equipment during the pandemic by expediting orders for parts made specifically for those machines.
Our manufacturing facilities remain open as per government mandate. DiaCom continues to exercise an abundance of caution by taking necessary precautions to ensure our essential workers are safe by following recommended guidelinesto prohibit the spread of the virus.
Once again, we would like to take a moment to salute and thank front-line workers for making personal sacrifices to help those affected by this pandemic. Our thoughts and prayers are with these individuals and those affected by the pandemic.

These natural, rubber-based elastomers offer a tough, high resilience, high flex life, low-cost option for applications that are not expected to be exposed to high temperatures or petroleum-based oils. Both compounds utilize the latest technology to use renewable resources and meet international regulations. Both elastomers can be used to mold complex geometry fabric-reinforced diaphragms, including those with metal inserts.

DiaCom Corporation is pleased to introduce diaphragms custom manufactured with advanced peroxide-cured perfluoroelastomer (FFKM) into our lineup. These diaphragms and seals are specially formulated for broad chemical resistance in multiple environments requiring flexibility and heat resistance. The compound used has outstanding hot air resistance, improved high temperature compression set resistance, good strength and flexibility, inherent ozone resistance and excellent permeability resistance. Diacom can mold this material with or without fabric reinforcement, and can over-mold it to metal inserts.

In efforts to manufacture diaphragms which are able to stand up to the most chemically aggressive of environments, DiaCom Corporation has once again innovated a new line of PTFE-faced diaphragms. DiaCom Corporation uses a variety of fluorinated films including PTFE, TFM, PFA, and FEP. These diaphragms are compatible with harsh environments without limiting their life and responsiveness. For additional strength, fabric reinforcement can be added to the PTFE composite. Bonded inserts of stanless steel, brass, plastic, and cold-rolled steel are often incorporated into these diaphragms as well to reduce process and assembly steps and add value.

The DiaCom Proprietary Double-coat process has been developed so the elastomer is not “formed” from calendared sheet stock but is molded from an equal amount of unvulcanized elastomer on each side of the fabric. This eliminates dimensional instability and ensures that the fabric is constantly oriented near the center of the part, which has traditionally been problematic with double coat diaphragms produced from calendared material.
