PFA Series White Knight Pumps

PTFE/PFA Pumps Capable of 100°C (212°F) with Fiber-Optic Control

Overview

click+drag to rotate

PFA Series pumps are the ideal solution for ambient temperature and ultra-pure recirculation or delivery applications where fiber optic sensors are required for optimum systems control. These PTFE/PFA pumps are completely metal free and operate with fiber optic sensors and an external solenoid valve. They perform safely and reliably running continuously throughout their warranty period. 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 three models, PFA030, PFA060 and PFA140, which are capable of maximum flow rates of 30, 60 and 140 lpm, respectively.

*May vary depending on configuration. Suction lift diminishes over time. Recommended installation level less than 3 ft. 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 PFASD030 and PFASD060 pumps require flooded suction and may have a reduced warranty unless prior arrangements are made with White Knight. Contact White Knight for details.
