Bellow Pumps


PSA Series pumps are the ideal solution for ambient temperature, ultra-high purity recirculation and delivery applications. These PTFE/PFA pumps are completely metal free and operate with the unique White Knight shuttle valve, which eliminates the need for complicated detents and manual resets. They perform safely and reliably running continuously throughout their two-year warranty. They may be run at air supply pressures up to 7 BAR (100 PSI) and are capable of running in thermal cycling applications with fluid temperatures up to 100°C (212°F) without a cooling jacket.

The pumps are available in four models, PSA015, PSA030, PSA060 and PSA140, which are capable of max flowrates of 15, 30, 60 and 140 LPM, respectively.
