PFA Series White Knight Pumps

Teflon® PTFE and PFA Pumps Capable of 100°C with Fiber-Optic Control

Overview

click+drag to rotate

PFA Series pumps are the ideal solution for ambient temperature and ultra-pure recirculation or delivery applications where fiber optic sensors are required for optimum systems control. These Teflon® 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 warranty period. They offer air supply pressures up to 7 Bar (100 psi) and operate in thermal cycling applications with fluid temperatures up to 100°C (212°F). The pumps are available in four models, PFA015, PFA030, PFA060 and PFA140, which are capable of maximum flow rates of 15, 30, 60 and 140 lpm, respectively.

*May vary by configuration or system. Suction lift diminishes over time. Recommended installation level less than 3 ft above source.
**dB Level at 100 psi 50 CPM (top) and 100 psi maximum CPM (bottom). Sound Levels measured in accordance with ISO9614-2:1997.
***Dry-run capable PFASD pumps require flooded suction and may have a reduced warranty. Contact White Knight for details.

Configuration

Different Outlet Fittings

Configuration:

*Fiber optics are required for operation. Standard configuration comes dual-probe WITHOUT fibers. See stroke detect option for fiber optic cables or single probe option.
*Pump operation in timer mode requires end-of-stroke detection (fiber-optic stoke detection) to prevent over-stroking. Operating pump in timer mode without end-of-stroke detection voids pump warranty.
*Pump requires use of the included White Knight quick exhaust valves (QEVs) or QEVs supplied by the customer used with the optional NPT adapter. Operating pump without QEVs voids pump warranty.
*Extended dry-run configuration requires flooded suction.
