Gas-tight, Double-diaphragm Pumps

A line of process pumps integrating a patented double-diaphragm system are said to exhibit superior levels of gas tightness and leakage prevention for safely transferring hazardous, toxic or rare gases.

Their redundant diaphragm arrangement, combined with additional head machining and sealing rings, creates a safeguard to contain gases without risk of escape, says the vendor, even if the primary, or “working,” diaphragm becomes damaged. Additionally, the system prevents contamination from external influences. These pumps typically will be specified for emissions sampling and monitoring, analytical instrumentation, and nuclear, chemical, and process engineering applications, among others.
