Overview
White Knight’s revolutionary legacy model pumps were the world’s first 100% metal-free, Teflon® PTFE and PFA pumps. White Knight has since improved upon legacy designs and released high-purity pumps that offer improved performance, better reliability, extended pump life, longer warranties, shorter delivery times, and more.
See replacement pumps (right). White Knight will continue support for legacy pumps. Contact us for details.
