Industry’s Best Warranty White Knight provides the industry’s best warranty. We are so confident in our product quality and service that we offer the best warranty available for ultra-pure pumps on the market. White Knight was the first to offer a hands-off warranty – promising customers no need for preventative maintenance during the warranty period.…
Liquid-side shafts allow for compact designs with no metals, rotating parts or foreign lubricants, which are requirements for conscientious semiconductor manufacturers.
White Knight’s Pneumatic Logic™ air system minimizes liquid pulsation and automatically resets shuttle valves after shutdowns. It has no detents to fail, no seals to fatigue, and ensures the spool is correctly placed at the end of each stroke.
Pump bellows take the brunt of the workload inside the pump. White Knight’s unique, long-lasting bellows design has been developed over many years utilizing our vast experience manufacturing with PTFE. They are made entirely in-house from the finest, 100% pure PTFE powder – which makes them ideal for handling harsh chemicals used in wafer fabrication…
White Knight Tongue-and-Groove Seals are the most reliable and re-useable sealing technology available in high-purity pumps. White Knight high-purity products use the seals on top-caps, fittings, heads, bellows, and more. The seals are machined into mated pump parts that act as barriers to liquid leaks. They are designed so that the tongues expand diametrically within…
White Knight’s stroke detection options enable pumps to be monitored electronically and allow for immediate notifications of changes in pumping conditions. They simplify replacement of other electronically monitored pumps, and may also be used to register pump speed or changes in pumping conditions.
Ensure Personnel Safety White Knight’s leak detection options provide notifications if liquid breaches the air-side of pumps. They are ideal for ensuring personnel safety in areas where dangerous chemicals are being pumped. Fiber optic and conductivity leak detection are available. Fiber Optic Leak Detection Fiber optic probes thread into pump heads at the lowest point…
All White Knight pump components that are subject to wear are engineered to be completely replaceable using factory manufactured parts. This provides for a long life of the main parts of the pump without requiring expensive pump replacement. While it would be easier to use some portions of main pump components as wear surfaces, White…
White Knight Buttress Threads provide stronger threaded connections and increase the level of safety for threaded connections between parts made from soft materials such as plastics and fluoropolymers (PTFE and PFA). White Knight’s 45º by 90º Buttress Threads place thread load linearly rather than diametrically. This greatly reduces the amount that mating threaded parts force…
White Knight pumps with liquid-side shafts use hydraulically-loaded seals that allow the perfect amount of pressure to the seal, regardless of the pump operating pressure. Shaft seals are held into sealing position by the pressure of the liquid being pumped. The seals tighten on the shaft when pumping pressure is high, and the force of…
