PSR Series Pumps

PSR Series pumps are the ideal solution for ambient temperature, ultra-pure recirculation 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 one-year warranty. They offer air supply pressures up to 4 Bar (60 psi) and operate in thermal cycling applications with fluid temperatures up to 100?C (212?F).

The pumps are available in PSR025 and PSR050, which are capable of maximum flow rates of 25 and 50 lpm, respectively.
