Chemical Blending, Mixing, Spiking

Metering Pumps to Accurately Dispense Corrosive Media

Metering Pumps

White Knight metering pumps offer adjustable flow rates for use in single-wafer processing tools or premix vessels to ensure exact chemistry mixtures, and allow for in-situ mixing directly at the head. They were designed for chemical replenishing, blending, dosing, and spiking applications, as well as uses in cleaning of CVD equipment and photolithography. They are ideal for photoresist, etch and clean processes, peroxide spiking in piranha mixtures, and other blending of chemical mixtures into process tanks prior to the introduction of substrates.

  • Fully adjustable stroke speeds
  • Safe, leak-free operation with no maintenance
  • No exposed metalics prevents corrosion and contamination
  • Fully-swept PTFE fluid path for ultra-pure applications
  • PTFE rolling diaphragm with PP housing
  • Easy to install in any orientation
