Pump Diaphragms Made from Elastomers
Pumps that operate with a diaphragm have been in use since the mid-1800s because of their simplicity and effectiveness.
That isn’t to say these pumps have remained unchanged in all that time. More than 150 years of innovation and technical improvements in diaphragm profiles and elastomeric material sciences have secured their use for a wide range of pumping and reciprocating applications.
The design and utilization of diaphragms in pumping applications is a vast topic, yet it is one that Gallagher Fluid Seals’ application engineers have mastered by approaching the manufacturing and design of diaphragms with a step-by-step process.

In the safety-driven natural gas industry, system leaks are a dangerous and costly issue. Residential gas meters and regulators, in particular, are at risk when crucial components such as diaphragms are not optimally designed and manufactured for the environment in which they will work.
An advanced polymer technology, trademarked by Freudenberg Sealing Technologies’ Metflex Precision Moulding organization, addresses these challenges with fiber-reinforced materials that improve the reliability, functionality and longevity of critical gas system components. Diaphragms made using Metflex Dispersed Fibre Technology (DFT)™ offer better sealing performance, longer flex life, improved low temperature resilience and enhanced design capabilities than standard diaphragms made from fabric coated polymers. To date, more than 40 million DFT diaphragms have been used in medium and low-pressure application, primarily in North America but also in other regions of the world.
