Proseries® Peristaltic Pump

Max Feed: 33 GPH (125 LPH)
Max Pressure: 125 PSI (8.6 bar)

Flex-Pro A3 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.


  • 2500:1 turndown ratio.
  • Output rates to: 33.3 GPH (126 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, 0-10Vdc, and Pulse inputs for remote external
    speed control and 0-30 VDC / contact closure remote start/stop.
  • Operator friendly digital touch pad with menu driven software.
  • VGA Graphic multi-color backlit LCD displays remote/local control status, motor speed,
    output rate, input signal values, service and alarm status.
  • Outputs include: Scalable 4-20mA or pulse, one 250V/6A relay and three 115V/1A contact closures
    assignable to monitor up to 17 different pump functions including TFD, FVS, remote/local
    control setting, motor on, fault, current operating mode, and others.
  • 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.
  • No maintenance brushless variable speed motor.
  • Specially engineered tubing for long life at high pressures. Meets FDA 21 CFR requirements
    for food contact applications.

FLEX-PRO A3 Dimensional Drawing

Quick Disconnect Fittings Available for Flex-A-Prene®

ORANGE Outlet / discharge fitting
has an automatic (active) functioning check valve, preventing chemical back flow.

NATURAL Inlet / suction fitting
functions as a check valve when tubing is detached, preventing loss of prime and spills while changing the tubing assembly. The valve is forced open when the tubing assembly is attached.
