The Purest Heart for Wet Process Equipment

Metal-Free, Corrosion-Resistant Pumps for Chemical Recirculation

High-Purity Pumps for Recirculation

White Knight shuttle-driven pumps are ideal for high-purity recirculation applications. They contain no metals and feature Teflon® PTFE and PFA fluid paths without any O-rings or foreign lubricants for optimal chemical compatibility and superior containment.They can pump up to 140 lpm (36 gpm), 60 lpm (16 gpm), or 30 lpm (8 gpm), depending on the model. White Knight’s Pneumatic Logic™ shift mechanism eliminates the need for complicated detents and manual resets. They will operate at red-line conditions throughout their two-year warranty periods.

PSA, PSH and PSU Series pumps are capable of temperatures up to 100°C (212°F), 145°C (293°F) and 210°C (410°F), respectively.

Need Fiber Optics or Pressure Switches?

White Knight pumps may also be controlled with fiber optics or pressure switches.
