  • Pressures to 125 PSI

  • 4-20mA, Pulse Input and Manual Speed Control

  • Optional Modbus, Profibus, Industrial Ethernet

  • 100:1 Turndown Ratio

  • Variable Speed DC Motor

  • NEMA 4X (IP 66) Washdown Duty

  • 2 Year Warranty

  • NEW! Flex-A-Prene® Tubing with more than 4X longer tube life.

  • Patented Tube Failure Detection

Features & 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: 14.9 GPH (56.2 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.

  • Optional: remote communications, Profibus DPV1, Modbus RTU, Modbus-TCP, EtherNet/IP, and Profinet RT I/O

  • 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.

Patented Features:

  • Patented Tube Failure Detection (TFD) system.
    Senses tube failure by detecting chemical in the pump head. No false triggering.

  • Patented feature to extended tube life.

    The Method comprises switching the inlet and outlet connections of the peristaltic pump, and reversing the rotational direction of the roller assembly, thereby moving the wear point of the tube which results in approximately double the useful life of the tubing.

    The patent includes: Identify usage information of the tubing of the peristaltic pump, and ability to stop the pump automatically after a certain number of rotor revolutions.

    Implementation of the method discussed above can also result in cost and time savings. Clearly, by extending the life of the tubing, replacement costs are substantially decreased. However, implementing such a method can also save production and replacement time that would otherwise be sacrificed in maintaining the system. Included on all Flex-Pro pumps.

  • Patented Safety Switch.

    Maintenance Mode Operating Feature

    Protects the pump operator when performing maintenance to the pump head, such as cleaning the pump tube. The switch stops the pump when front cover is removed. The pump will only operate in maintenance mode while the front cover is removed, helping to ensure operator safety. Included on all Flex-Pro pumps.
