PFH Series pumps are the ideal solution for high 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 two-year warranty. They offer air supply pressures up to 5.5 Bar (80 psi) and operate in thermal cycling applications with fluid temperatures up to 145°C (293°F).
The pumps are available in three models, PFH030, PFH060 and PFH140, which are capable of maximum flow rates of 30, 60 and 140 lpm, respectively.
