Raising the Bar in Chemical Delivery

Highest Operating Pressure and Most Displacement of Corrosion-Resistant, Metal-Free Pumps

Pumps for Chemical Delivery

White Knight PSA Series high-purity pumps are durable, reliable, and require low maintenance. They feature PTFE/PFA fluid paths for optimal chemical compatibility. They do not have metals, elastomer O-rings, impellers or electric motors. These chemical delivery pumps are designed for flow rates up to 140 lpm (36 gpm), depending on model. They are capable of temperatures up to 100°C (212°F) and air pressures up to 7 Bar (100 psi). White Knight’s Pneumatic Logic™ offers full dead-head capabilities and reliable restarts without intervention.

Need Higher Temperatures?

White Knight offers pumps capable of operating at up to 145°C (293°F) or 210°C (410°F), depending on model.
