PSA Series pumps are the ideal solution for ambient temperature, ultra-pure recirculation and delivery applications. These PTFE and PFA pumps are completely metal free and operate with a unique shuttle valve that eliminates the need for complicated detents and manual resets. They perform safely and reliably running continuously throughout their two-year warranty. They offer air supply pressures up to 7 Bar (100 psi) and operate in thermal cycling applications with fluid temperatures up to 100°C (212°F).
The pumps are available in four models, PSA015, PSA030, PSA060 and PSA140, which are capable of maximum flow rates of 15, 30, 60 and 140 lpm, respectively.
