Flex-Pro A4 Series Peristaltic Pump for high pressure and high accuracy applications.

  • Feed Rates to 158.5 GPH

  • Pressures to 125 PSI

  • 2500:1 Turndown ratio

  • Patented Tube Failure Detection

  • Brushless DC Motor

  • NEMA 4X (IP 66) Washdown

  • 2 Year Warranty

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: 158.5 GPH (600 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.
