PTFE Pumps
White Knight PTFE pumps deliver reliable performance for corrosive and toxic fluids in semiconductor and industrial applications. Our bellows, diaphragm, and metering pumps feature leak-proof designs with flow rates up to 140 lpm and pressure capabilities to 7 Bar. Engineered for deionized water, acids, fuels, and solvents, these metal-free pumps eliminate contamination risks while maintaining precise chemical dispense accuracy. The Class 100 cleanroom assembly ensures ultrapure fluid handling for critical manufacturing processes.
Chemical Heaters
Our high-purity chemical heaters provide precise temperature control for semiconductor and industrial processes. The Aquarius DI water systems and Accuheat quartz/PFA heaters maintain 1C stability with flow rates to 36 gpm. Designed for aggressive chemicals like hydrofluoric acid and potassium hydroxide, these heaters feature PVDF/PFA wetted surfaces and microprocessor-based temperature controllers. The HX50 compact models offer space-saving solutions for low-flow applications requiring accurate thermal management.
Debubblers
White Knight debubblers eliminate air bubbles from high-purity chemical delivery systems using patented tongue-and-groove seal technology. The CBA and CBU series operate at temperatures to 210C with pressure ratings up to 100 psi, ensuring bubble-free fluid transfer for wafer processing and chemical dispense applications. Available with level sensors and sight tubes, these units integrate seamlessly into semiconductor manufacturing lines while maintaining Class 100 cleanroom compatibility.
Filter Housings
Our PTFE/PFA filter housings provide high-flow filtration solutions for ultrapure chemical systems. The FHA and FHU series accommodate standard Code 0 cartridges in dual- or quad-bowl configurations, supporting parallel or series operation. With temperature ratings to 210C and pressure capabilities up to 100 psi, these non-metallic housings feature leak-free dual-static crush seals that maintain fluid integrity in semiconductor and pharmaceutical applications.
Pressure Regulators
White Knight pressure regulators maintain precise system pressure in high-purity chemical applications. The PTFE/PFA regulators offer remote piloting capability for circulation loops with multiple dispense points. Available in ", ", and 1" configurations, these units operate at temperatures to 100C with pressure control ranges from 0-40 psi to 30-60 psi. The metal-free design eliminates contamination risks while ensuring stable pressure regulation for critical semiconductor processes.
