White Knight Fiber-Optic Pumps

PTFE and PFA Bellows Pumps Controlled with Fiber-Optics


White Knight fiber-optic-controlled bellows pumps operate with fiber optic sensors and an external solenoid valve. They feature PTFE and PFA fluid paths without any impellers, magnets, elastomer O-rings or foreign lubricants. They operate continuously throughout their two-year warranty period with no required maintenance. Pump models are designed for various temperatures with maximum flow rates of 30, 60 or 140 lpm.

Select pumps by control method, temperature ratings, and pressure capabilities.
