White Knight AP-FM Series Pumps

Reliable PTFE and PFA Pumps for Recirculation of Harsh Chemicals

AP FM Series pumps are discontinued. Please upgrade to PSH Series pumps for better performance, improved reliability, shorter lead times, extended pump life, and increased warranty periods. See pump comparison information below.

Overview

AP-FM Series pumps are completely metal-free with PTFE and PFA fluid paths. They are capable of distributing chemicals at temperatures up to 100°C (212°F) and allow for air supply pressures up to 4 Bar (60 psi). The pumps perform safely and reliably running continuously throughout their one-year warranties. The pumps are available in four models AP50FM, AP100FM, AP200FM and AP300FM, which are capable of maximum flow rates of 20, 55, 68 and 115 lpm, respectively.

Features & Benefits
