FLEXFLO® Peristaltic Metering Pump
The FLEXFLO® M1 Peristaltic Metering Pump offers reliable chemical feed with simple-to-use controls and precise adjustability. Ideally suited for low to medium flow applications, this compact, rugged self-priming pump delivers smooth chemical feed and does not require check valves or seals that can clog, leak, or corrode.
Remote control signal options include Remote Start/Stop, Flow Verification, and 4-20mA.
The “M1C” Control model features 4–20 mA input and output, remote start/stop, alarm relay output, and flow verification sensor compatibility (MS6 or MICRO-FLO), while the “M1B” Base model is designed for manual, stand-alone operation with no I/O.
