PFU Series White Knight Pumps

PTFE/PFA Pumps Capable of 210°C (410°F) with Fiber-Optic Control

Overview

click+drag to rotate

PFU Series pumps are the ideal solution for ultra-high temperature and ultra-pure recirculation or delivery applications where fiber optic sensors are required for optimum systems control. These PTFE/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 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, PFU030, PFU060 and PFU140, which are capable of maximum flow rates of 30, 60 and 140 lpm, respectively.

*May vary depending on configuration. Suction lift diminishes over time. Recommended installation level less than 3 ft. above source.
**dB Level at 60PSI 50CPM (top) and 60PSI maximum CPM (bottom). Sound Levels measured in accordance with ISO9614-2:1997.
***Dry-run capable PFUSD030 and PFUSD060 pumps require flooded suction and may have a reduced warranty unless prior arrangements are made with White Knight. Contact White Knight for details.
