White Knight Shuttle Pumps

PTFE and PFA Bellows Pumps Controlled with Shuttle Valves


White Knight metal-free, high-purity pumps with shuttle valves feature Pneumatic Logic™ and PTFE and PFA fluid paths without any impellers, magnets, O-rings or foreign lubricants. They operate continuously throughout their warranty period with no required maintenance. Pump models are designed for various temperatures and applications with max flow rates of 30, 60 or 140 LPM.

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