Overview
AP-FM Series pumps are completely metal-free with Teflon® PTFE and PFA fluid paths. They are capable of distributing 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 warranties. The pumps are available in four models AP50FM, AP100FM, AP200FM and AP300FM, which are capable of maximum flow rates of 20, 55, 68 and 115 lpm, respectively.
While White Knight continues to offer and support AP-FM Series pumps, we recommend users consider PSH 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 50 CPM (top) and 60 psi maximum CPM (bottom). Sound Levels measured in accordance with ISO9614-2:1997.
***Dry-run capable PSHSD030 and PSHSD060 pumps require flooded suction and may have a reduced warranty unless prior arrangements are made with White Knight. Contact White Knight for details.
