White Knight’s recently released pressure vessels offer high-purity chemical dispense with absolutely no pulsation. They provide laminar flow at the point of use and serve as holding or mixing tanks for high-purity chemicals. They feature chemically-resistant PTFE and PFA fluid paths for dispense and mixing applications.
White Knight’s FHA Series filter housings combine compact size, superior containment, and high-flow performance. The housings contain no metal parts and allow for filters to be changed without disconnecting liquid lines.
White Knight Fluid Handling is pleased to announce the release of the much-anticipated PEM050 electronic metering pump for chemical replenishing, blending, dosing, and spiking applications. The PEM050 dispense up to 50 ml of high-purity chemical with ±0.01% repeatability at high pressures (60-80 psi). They feature PTFE fluid paths and fully supported rolling diaphragms to…
The Closed-Loop Controller (CPC-1) automatically adjusts to maintain a set pressure or flow rate in high purity, closed-loop chemical pumping systems to compensate for variables in wafer processes, such as opening/closing chamber valves or clogging filters. The controlled closed-loop system improves process repeatability, increases chip yields, and simplifies automation to save customers time and resources.…
White Knight’s Cycle Rate Translator (CPT-1) enables pump swap-outs in existing tools. The CPT-1 operates White Knight pumps at their optimal cycle rate and communicates a scaled operational cycle rate to match that expected by the tool. It also manages cycle rate errors and eliminates steady-state cycle rate alarms.
DBA and DBH Series in-line and top-mount pulse dampeners augment the capabilities of White Knight high purity pumps. They reduce pulsation in fluid systems to improve flow control, increase batch yields, protect filters, fittings and pipes, and minimize downtime for system repairs. DBA and DBH Series dampeners operate in temperatures up to 100°C (212°F) and 145°C (293°F), respectively.
PSD Series air-operated double-diaphragm pumps, or AODD pumps, for industrial chemical, semiconductor, solar, LEDs and flat-panel display manufacturing markets offer improved performance, optimized efficiency, simplified maintenance, and reduced noise levels. Their leak-proof, icing-resistant plastic design provides constant, reliable, and safe operation – even with the most corrosive chemicals. PSD Series pumps are available in…
White Knight’s high-purity PPM100 pneumatic metering pumps feature PTFE fluid paths. They are capable of dispensing up to 100 ml of corrosive media with +/-0.1% repeatability at high-pressure (60-85 psi). The pumps offer adjustable flow rates for use in single-wafer processing tools or premix vessels to ensure exact chemistry mixtures, and they allow for in-situ mixing directly at the head.
