An unexpected error has occurred.

Our Parabola® variable frequency drive (VFD) control panels are advanced pre-engineered simplex, duplex, and triplex control panels with a user-friendly HMI control interface and are designed for level, constant pressure, commercial pressure boosting applications. These control panels are also equipped with our Pacific 2.0 software, which provides extensive system customization options and easy user guide tools with step-by-step instructions for the adjustable fields. Our pre-engineered Parabola® control panels are UL listed for the United States and Canada, and they come standard with a two-year limited manufacturer’s warranty.


Pacific 2.0 Logo


  • Single or three phase voltage supply, designed to control 208/240/480VAC pump(s)
  • Pump protection: Motor protective switch included for each (branch circuit protection, adjustable overload and disconnect)
  • Remote monitoring dry contacts: High/low level alarms, summary alarm/fault (normally open)
  • NEMA 3R rated enclosure: Painted steel with lockable front door and through door main disconnect
  • 7" screen with 800x480 resolution and a resistive film touch panel
  • Supports Modbus RTU/TCP, BACnet® IP/MSTP, and additional communication protocols
  • Panel and controls are UL listed for the United States and Canada

  • Simple level transducer calibration setup
  • Flip switch for transducer and float mode
  • Selectable alternation pattern: Cycle or timed
  • Multiple access levels for added security
  • Adjustable set points:
    • Simplex: Low Level, Stop, Start, High Level (Adjustable lead pump start and stop set points)
    • Duplex: Low Level, Stop, Lead, Lag, High level
  • Optional feature: Pump down constant level management PID loop
  • Pump run data logging: Records each pump event - start time, stop time, and run duration
  • Automatic system restart
  • HMI touchscreen display features:
    • Hand-Off-Auto (H.O.A.) switch for each pump
    • Green Pump Run indicators
    • Red Pump Fault indicators
    • Pump and level status screens
  • Alarm/Fault history: Data logging gives access to 250 fault conditions with date and time (optional access to auto-save alarm history to USB drive)
  • Backup float override operation: User-configurable feature that automatically switches to float-based operation in the event of a transducer error
  • No flow protection: User-configurable feature that inhibits pumping during no flow conditions


  • Pump Down: Lift stations, sewage pumps, grinder pumps, sump pump basins, wastewater applications, other dewatering applications
  • Constant Pressure: Irrigation systems, chemical feed systems, cooling towers, commercial pressure boosting systems, building water supply systems

    **Additional fee will apply for monthly or annual subscription.

    HMI Navigation

    The Parabola® features a comprehensive HMI touchscreen device with our Pacific 2.0 software that allows for complete monitoring of tank level status, alarm/fault history, and pump run data.


    The HMI’s main menu displays live pump data and H.O.A. switch(es). This menu is your command center.


    You can easily setup the Parabola’s Pump On, Pump Off, High, and Low levels - all with the touch of a button!

    Pump Status

    Status of all processes. You can view Pump Fault, Run Time, and other necessary information associated with the pump operation.

    Alarm/Fault History

    Data logging gives you access to up to 250 conditions with date and time.
