White Knight Demonstrates High-Purity Flow and Pressure Control Systems at Semicon West 2015
Main demonstrations compared White Knight’s high-purity pump systems to centrifugal systems. Flow pulsations from White Knight pumps and centrifugal pumps are both relatively low and nearly identical, regardless of the operating conditions tested. There was no measurable difference in filter retention between the White Knight pumps and centrifugal pumps tested.
Most importantly, temperature stability tests showed that White Knight pumps did not increase fluid bath temperature, while the centrifugal pump increased the fluid temperature by 10°C in 2 hours, and more than 30°C in 8 hours. White Knight closed-loop control systems are also capable of operating in temperatures up to 210°C (410°F). White Knight pumps are able to maintain steady temperatures due to their metal-free designs, unlike the centrifugal pump which relies on electric motors, impellers and magnets.
