Overview

click+drag to rotate

PXH Series pumps are the ideal solution for high temperature and ultra-pure 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 switches and 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, PXH030, PXH060 and PXH140, which are capable of maximum flow rates of 30, 60 and 140 lpm, respectively.
