PSA Series pumps are the ideal solution for ambient temperature, ultra-pure 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 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.

*May vary depending on configuration. Suction lift diminishes over time. Recommended installation level less than 3' above source.
**dB Level at 60PSI 50CPM (top) and 60PSI maximum CPM (bottom). Sound Levels measured in accordance with ISO9614-2:1997.
***Dry-run capable PSASD030 and PSASD060 pumps require flooded suction and may have a reduced warranty unless prior arrangements are made with White Knight. Contact White Knight for details.
