White Knight Centrifugal Pump with Magnetically Levitated Impeller

Centrifugal Pumps

White Knight high-purity centrifugal pumps feature a magnetically levitated impeller that is rotated independent of its stabilization functions. It offers continuous, steady flow without pressure pulsation. It features a process-safe PTFE/PFA flow path and precise controls.

Centrifugal Pumps
White Knight High-Purity Air-Operated Double-Diaphragm Pumps

Diaphragm Pumps

White Knight pneumatic diaphragm (AODD) pumps feature PTFE or UHMW polyethylene (UHMWPE) corrosion-resistant fluid paths. They are ideal for corrosive or toxic liquids such as acids, fuels, glues, paints, resins, inks, or slurry.

Diaphragm Pumps
White Knight Metering Pumps for Chemical Dispense

Metering Pumps

White Knight pneumatic and electronic metering pumps accurately dispense up to 100 ml and 50 ml, respectively. Their fully-supported PTFE rolling diaphragms maximize pressure capabilities and ensure safe, reliable chemical dispense.

Metering Pumps
White Knight PPMC Mini-Pump for High-Purity Chemicals


Mini-pumps offer up to 300 ml/min flow rates and 160 psi discharge pressures. They feature PTFE and PFA fluid paths, and spring-loaded checks enable them to mount in any direction.

CBA Debubbler Pressure Vessels


White Knight debubblers reduce bubbles from chemical delivery and wafer process systems. They feature chemically-resistant PTFE and PFA fluid paths for high-purity chemical applications.

White Knight High-Purity Back-Pressure Regulators

Pressure Regulators

Automatically maintain and accurately control pressure for circulation loops or multiple dispense points without additional circuitry or feedback. Pressure regulators are remotely piloted and feature fully-swept PTFE and PFA flow paths.

Pressure Regulators
White Knight Non-Metalic High-Purity Filter Housings

Filter Housings

Universal, compact, multi-chamber filter housings with PTFE and PFA fluid paths for high-purity chemicals. Dual-bowl and quad-bowl filter housings are available in parallel or in-line (series) models.
