Flex-Pro® A2

ProSeries® Peristaltic Pump

Max Feed: 19.3 GPH (72.9 LPH)
Max Pressure: 125 PSI (8.6 bar)

Flex-Pro A2 Series Peristaltic Pump for high pressure and high accuracy applications.





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.


  • 100:1 turndown ratio.
  • Output rates to: 19.3 GPH (72.9 LPH) and pressures to 125 PSI (8.6 Bar).
  • Inject at maximum pressure in either direction (clockwise and counter clockwise).

Communication & Interface:

  • SCADA Inputs include: 4-20mA and pulse inputs for remote external speed control
    and either powered 6-24 VDC or non-powered dry contact closure for remote start/stop.
  • Operator friendly digital touch pad with menu driven software.
  • Backlit LCD displays motor speed, input signal values, service and alarm status.
  • Outputs include: one 250V/3A relay to monitor TFD (Tube Failure System) and
  • FVS (Flow Verification System). A 4-20mA analog output signal scaled to the motor speed is optional.
  • Compatible with Blue-White’s output Flow Verification Sensor (FVS) system.

Superior Engineered Design:

    • Two CNC precision machined squeeze rollers and two alignment 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.
    • Variable speed DC motor.
    • Specially engineered tubing for long life at high pressures. Meets FDA 21 CFR requirements
      for food contact applications.
