Features & Benefits
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 Range: .001 – 35.19 GPH (.003 – 133.2 LPH) and pressures to 125 PSI (8.6 Bar).
  • 2500:1 turndown ratio.
  • 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.
