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 and 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 four models, PFA015, PFA030, PFA060 and PFA140, which are capable of maximum flow rates of 15, 30, 60 and 140 lpm, respectively.
