PXU Series White Knight Pumps

PTFE/PFA Pumps Capable of 210°C (410°F) with Proximity Switch Controls

Overview

click+drag to rotate

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/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.
