PXU Series pumps are the ideal solution for ultra-high temperature and high-purity recirculation or delivery applications where proximity sensors are required for optimum systems control. These PTFE and PFA pumps are completely metal free and operate with proximity sensors 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 7 Bar (100 psi) and operate in thermal cycling applications with fluid temperatures up to 210°C (410°F).
The pumps are available in three models, PXU030, PXU060 and PXU140, which are capable of maximum flow rates of 30, 60 and 140 lpm, respectively.
