High-Temperature Pumps

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 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.
