FLEXFLO® Peristaltic Metering Pump

The FLEXFLO® M5 Peristaltic Metering Pump is truly an advancement in high-volume precision fluid metering. This energy-efficient pump is capable of delivering outputs up to 8.9 gallons per minute at only 75 RPM motor speed, maximizing tube life and reducing overall maintenance. The M5 also reduces pulsation by up to 80% through its exclusive offset roller design and dual-channel tube assembly.

The M5 is a fully enclosed and easily configurable pump that does not require external control devices to operate. It features a large 5″ display for easy viewing with simple and intuitive touchscreen controls and icon-driven menu navigation. M5 remote control signal options include Pulse, 4-20mA, Modbus TCP, EtherNet/IP™, and PROFIBUS for enhanced supervision and automation for critical metering and transfer applications.
