Features

Benefits:
  • Self-priming – even against maximum line pressure. By-pass valves are not required. Cannot vapor lock or lose prime. 30ft of suction lift. Gentle low shear pumping action.
  • Tube Failure Detection (TFD) senses tube rupture by detecting chemical in the pump head. No false triggering – Patented
  • Optional dual channel tube design for optimum performance and pressure capability
Communication and Interface:
  • Operator friendly digital controls with backlit LCD displays motor speed, input signal values, service, and alarm status
  • 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
  • Outputs: one 250V/3A relay to monitor TFD (Tube Failure System) and FVS (Flow Verification System), one 4-20mA analog signal scalable to the motor speed and one relay output for run status
  • Compatible with Blue-White’s output Flow Verification Sensor (FVS) system. Sensor is sold separately
Superior Design:
  • 2 Year Warranty
  • 100:1 turndown ratio
  • NEMA 4X (IP66) wash-down, chemically resistant powder coated enclosure
