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.

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.


  • Output rates to: .0001 – 5.6 GPH (.0004 – 21.2 LPH) and pressures to 100 PSI (6.89 Bar).

Communication & Interface:

  • Remote Start/Stop: Non-powered dry contact closure for remote start/stop.
  • Relay outputs include a single 250V / 3A and a single solid-state.
  • Compatible with Blue-White’s output Flow Verification Sensor (FVS) system.
  • 4-20mA SCADA input.

Superior Engineered Design:

  • 5 Year Warranty
  • CNC precision-machined squeeze rollers for optimum squeeze, unparalleled accuracy, and tube life.
  • Heavy-duty rotor – single piece plastic rotor means no flexing and increased accuracy with no metal springs or hinges to corrode.
  • Energy-efficient brushless DC motor.
  • Specially engineered tubing for long life.

Safety Features:

  • Enhanced Tube Failure Detection (TFD+) Senses tube rupture by detecting chemicals in the pump head. No false triggering – Patented
  • Lockout feature prevents any unwanted tampering – Patent pending
  • Display shield to protect controls from harsh environments

What’s Included:

  • M1 Peristaltic Metering Pump
