Features & Benefits

  • Designed for Water Systems, Optimized for Constant Pressure: Designed specifically for water pumping applications, SubDrive Connect Plus delivers unique features:
    • Provides consistent water pressure across a system, eliminating fluctuations
    • Dual set point and adjustable drawdown for exact pressure control
    • Soft start maximizes system life
    • Run/stop and hand/auto control
    • Additional built-in protections include:
      • Pipe fill mode to reduce water hammer
      • Underload (Dry-run) with customizable sensitivity and off time
      • Overload / Locked pump
      • Broken pipe detection
      • Output short circuit and open circuit
      • Undervoltage
      • Electrical surge
      • Overheated controller
      • Moisture sensor input
      • Run and fault relays
  • Simple Installation, Made Easier Through Connectivity: The easy-to-install platform uses an array of setup, local monitoring, and assisted troubleshooting solutions to help you save time during installation and servicing:
    • LCD display provides immediate feedback and read-outs of pressure and system status
    • No advanced programming is required with single-level menu and DIP switches for basic drive configuration
    • Integrated connectivity and compatibility with our FE Connect mobile app for real-time data and monitoring; access to advanced features such as motor frequency range, lead/lag/alternation, broken pipe detection, and fault log retrieval
  • Versatility for Multiple Applications:
    • Ideal for new construction or retrofitting and optimizing submersible and surface systems up to 30 horsepower, including projects powered by MagForce High Efficiency Motors
    • Built-in lead/lag and alternation capability for up to 8 drives
    • Phase conversion allows for single-phase or 3-phase input in 230 V models
    • Comes standard with various input/output (I/O) connections or terminals for streamlined compatibility with adjacent systems
  • Smaller Footprint, Smarter Use of Space:
    • Compact design, that is ideal for wall-mounting, provides a cost-effective solution when compared to high-horsepower systems that use starters or VFD panel packages
    • Can be used indoors or outside since the self-contained NEMA 3R-rated drive provides a degree of protection against falling rain or sleet
