White Knight Proximity Pumps

PTFE and PFA Bellows Pumps Controlled with Proximity Sensors


White Knight proximity sensor-controlled bellows pumps operate with proximity switches and a solenoid valve. They feature process-safe PTFE and PFA fluid paths without any impellers, elastomer O-rings or foreign lubricants. They operate continuously throughout their two-year warranty period with no required maintenance. Pump models are designed for various temperatures with maximum flow rates of 30, 60 or 140 lpm.

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