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.
Capabilities:
  • Output rates to: .003 – 5.6 GPH (.011 – 21.2 LPH) and pressures to 100 PSI (6.89 Bar).
Communication & Interface:
  • Remote Start/Stop: Non-powered dry contact closure for remote start/stop.
  • Relay outputs include a single 250V / 3A and a single solid-state.
  • Compatible with Blue-White’s output Flow Verification Sensor (FVS) system.
  • SCADA Inputs/Outputs include: 4-20mA. (Included with A1V only)
Superior Engineered Design:
  • 2 Year Warranty
  • CNC precision-machined squeeze rollers for optimum squeeze,unparalleled accuracy, and tube life.
  • Heavy-duty rotor – single piece plastic rotor means no flexing and increased accuracy withno metal springs or hinges to corrode.
  • Energy-efficient brushless DC motor.
  • Specially engineered tubing for long life.
Safety Features:
  • Enhanced Tube Failure Detection (TFD+) Senses tube rupture by detecting chemicals in the pump head. No false triggering – Patented
  • Lockout feature prevents any unwanted tampering – Patent pending
  • Display shield to protect controls from harsh environments
