What is the Parabola® VFD Control Panel?

Take a deeper look at our Parabola® VFD Control Panel, a flexible, pre-engineered solution designed for level control, constant pressure, and commercial pressure boosting applications where precision and efficiency matter.

What is the Parabola®?

The Parabola® is a complete line of simplex, duplex, and triplex variable frequency drive (VFD) control panels engineered to deliver intelligent pump control, energy efficiency, and long-term reliability across a wide range of water and wastewater applications.

Parabola® control panels are:
  • Pre-engineered and UL listed for the United States and Canada
  • Designed for level control, constant pressure, and pressure boosting
  • Backed by a two-year limited manufacturer’s warranty

Built for Water & Wastewater Applications

Parabola® control panels are commonly used in:
  • Lift stations
  • Sewage pump systems
  • Grinder pump systems
  • Sump pump basins
  • Dewatering applications
  • Irrigation and commercial pressure boosting
  • Building water supply systems
Each system is engineered to deliver smooth pump operation, reduced wear, and simplified configuration in the field.

Intelligent Control with VFD Performance

Parabola® panels are designed around advanced VFD logic to optimize pump performance and system efficiency. Standard control features include:
  • Selectable alternation patterns: Cycle or timed
  • Adjustable setpoints for all configurations
    • Simplex: Low Level, Stop, Start, High Level
    • Duplex: Low Level, Stop, Lead, Lag, High Level
    • Triplex: Low Level, Stop, Lead, Lag, Lag 2, High Level
  • Optional pump-down constant level PID control
  • Automatic pump alternation
  • High demand operation for multi-pump run conditions

Simple Calibration & Backup Protection

Parabola® panels are designed for straightforward setup and reliable operation in harsh environments.

Key functionality includes:
  • Simple transducer calibration through the HMI
  • Flip switch for transducer or float mode
  • Backup float override operation that automatically switches to float control if a transducer fault occurs
  • No-flow protection to inhibit pumping during dry or fault conditions
  • Pump run data logging including start time, stop time, and run duration

Pacific 2.0™ Comes Standard with Every Parabola®
