A5

FLEXFLO® Peristaltic Metering Pump

The FLEXFLO® A5 Peristaltic Metering Pump delivers high-volume precision fluid metering, with energy efficiency and reduced maintenance needs. It minimizes pulsation by up to 80% thanks to its exclusive offset roller design and dual-channel tube assembly. The M5 is fully enclosed, easily configurable, and offers intuitive touchscreen controls, remote control signal options, and a large 5″ display for enhanced metering and transfer applications.
