High-Purity Pumps for Recirculation

White Knight shuttle-driven pumps are ideal for high-purity recirculation applications. They contain no metals and feature 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.

Economical Option

White Knight PSR Series pumps are an economical option capable of pumping up to 50 lpm (15 gpm) or 25 lpm (6 gpm), depending on the model. They offer air supply pressures up to 4 Bar (60 psi).

High-Purity Closed-Loop Pump Systems

Automatically maintain laminar flow or steady pressure. White Knight closed-loop systems feature metal-free pumps with PTFE and PFA flow paths. They provide stable temperatures, dead-head, and suction lift.

White Knight’s closed-loop systems provide complete control of high-purity chemical processes and delivery systems. They simplify process automation to save customers’ time and resources, and they reduce costs by eliminating the need for expensive pressure systems.
