White Knight Legacy Pumps

Revolutionary PTFE Pumps for High-Purity Chemicals

Overview

White Knight’s revolutionary legacy model pumps were the world’s first 100% metal-free, 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.
