Certified Training White Knight provides comprehensive training for all employees and distributors…
White Knight air-operated double-bellows pumps are used to manufacture semiconductors, photovoltaic solar cells, LEDs, flat-panel displays and electronics. These high-purity chemical pumps feature PTFE and PFA fluid paths. They do not contain metals, elastomer O-rings, or electric motors. Their reliable designs use minimal parts, and operate continuously throughout their warranty period with no required maintenance.
Select pumps by control method and temperature ratings.
White Knight pumps series include models capable of 30, 60, and 140 lpm flow rates.
White Knight designed the world’s first metal-free PTFE and PFA pumps, and the first chemical pumps capable of 210°C (410°F). White Knight still supports legacy pumps, but also offers upgraded pumps with improved performance, better reliability, extended pump life, longer warranties, and shorter lead times. Contact White Knight for details.
Automatically maintain laminar flow or steady pressure. White Knight closed-loop systems feature metal-free pumps with PTFE and PFA flow paths. They provide stable temperatures, dead-head, and suction lift.
