High-Temperature Pumps

Teflon® PTFE and PFA Bellows Pumps for ≤210°C (410°F)


White Knight ultra-high temperature pumps operate up to 210°C (410°F). They are available with fiber-optics (F), shuttle valves (S), or proximity sensors (X), and they are available with maximum flow rates of 30, 60 or 140 lpm. The pumps feature Teflon® PTFE and PFA flow paths with no metals, elastomer O-rings, lubricants, or impellers. They operate continuously throughout their two-year warranty period with no required maintenance.

Select pumps by control method, temperature ratings, and pressure capabilities.
