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 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.
    • Inputs include: 4-20mA, 0-10Vdc, and Pulse inputs for remote external speed control and 0-30 VDC / contact closure remote start/stop
    • 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.

Superior Design:
  • 5 Year Warranty
  • 10,000:1 turndown ratio
  • NEMA 4X (IP66) wash-down, chemically resistant powder coated enclosure
  • Heavy duty rotor means no flexing and increased accuracy with no metal springs or hinges to corrode.
Safety Features:
  • Tube Failure Detection (TFD) senses tube rupture preventing hazardous chemical spills
  • Security programmable 4-digit password to prevent tampering
