Standardize on one chemical feed solution with the FLEXFLO® A1F Peristaltic Chemical Metering Pump. The A1F never loses prime, requires minimal maintenance, and has a high energy efficient rating. 

This self priming chemical metering pump delivers smooth chemical feed, and does not require check valves.


  • Feed Rates to 5.60 GPH (21.19 LPH)
  • Pressures to 100 PSI (6.89 bar)
  • Brushless DC Motor
  • NEMA 4X (IP 66) Washdown Duty
  • 3 Year Warranty
  • Patented Tube Failure Detection

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: 5.60 GPH (21.19 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.

Superior Engineered Design:

  • 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.

Tube Failure Detection (TFD) System

Patent No. 7,001,153 and 7,284,964

No False Triggering!

Breakthrough technology for Peristaltic Pumps.

The TFD system will detect a wide range of chemicals (i.e. chlorine, acids, soaps, etc.). This unique technology was designed NOT to false trigger by condensation and washdown. Many companies require the TFD system for their peristaltic pumps.

How does it work?

If a chemical is detected in the pumphead (by tube failure), the pump will automatically shut off and energize a relay, permitting communications with external equipment, such as an alarm or a SCADA system. The chemical must be cleaned from the pump head and the tubing should be replaced before the pump will start again.

  • The TFD system ships as standard on the most popular peristaltic pump models.No extra cost to you.
  • The sensors are located within the pumphead. Sensors are constructed of chemical resistant Hastelloy-C.
  • Only Blue-White offers this technologyPatent No. 7,001,153 and 7,284,964
