Overview
X Series pumps are metal-free with PTFE and PFA fluid paths. They distribute chemicals at temperatures up to 100°C (212°F) and allow for air supply pressures up to 4 Bar (60 psi). The pumps perform safely and reliably running continuously throughout their one-year warranty. The pumps are available in two models, X50 and X100, which are capable of maximum flow rates of 20 and 55 lpm, respectively.
While White Knight continues to offer and support X Series pumps, we recommend users consider PSA Series or PSR Series pumps, which provide better performance, increased flow rates, higher pressure capabilities, improved reliability, extended pump life and warranty periods, as well as shorter lead times. See comparisons below.

*May vary depending on configuration. Suction lift diminishes over time. Recommended installation level less than 3 ft above source.
**dB Level at 60 psi 50CPM (top) and 60 psi 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.
