CHEM-FEED® Multi-Diaphragm 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.

Key Features
Benefits of a Peristaltic Pump
- Peristaltic pump design does not have valves that can clog requiring maintenance.
- Self-priming – even against maximum line pressure. By-pass valves are not required.
- Cannot vapor lock or lose prime.
Capabilities
- Output rates to: .0001 – 5.6 GPH (.0004 – 21.2 LPH) and pressures to 100 PSI (6.89 Bar).
Communication & Interface (Included with “C” Control)
- Input: 4–20 mA external control
- Input: Remote Start/Stop via non-powered dry contact closure
- Input: Flow verification input compatible with MS6 and MICRO-FLO sensors
- Output: Alarm relay output, 250V / 3A
- Output: Motor On/Off solid-state relay output
- SCADA-compatible 4–20 mA input and output (Included with M1C only)
Superior Engineered Design
