Blue Diamond MaxiBlue® V2 — Intelligent Condensate Management for Modern HVAC

The MaxiBlue® V2 (X88-701) is Blue Diamond's most advanced mid-range condensate pump, engineered for air conditioning systems up to 14kW. Building on the proven MaxiBlue platform, the V2 introduces a smart control board, CondenSense™ technology, and an enhanced brushless motor — delivering quieter operation, lower energy consumption, and a maintenance-free service life that demands nothing from the engineer once installed.

Its valveless, clog-resistant, filter-free architecture removes the need for routine servicing. The integrated CondenSense™ reservoir allows the pump to self-adjust condensate flow in real time, preventing overflow and adapting automatically to changing system conditions. The result is a pump that works harder, lasts longer, and requires less attention — ideal for demanding commercial and residential HVAC installations.

Key Features

  • Ultra-quiet soft-start operation — 21 dB(A) maximum
  • Enhanced Rotary Diaphragm technology for improved pumping efficiency
  • Smart control board with real-time monitoring and automatic flow adjustment
  • CondenSense™ compatible — CS2 microchip integration for intelligent level sensing
  • Valveless, clog-resistant, filter-free design — zero routine maintenance
  • Energy-efficient brushless motor with ball-raced bearings for extended service life
  • Conformal-coated wiring for protection in high-humidity environments
  • Integrated elastomeric feet for vibration damping and noise reduction
  • Volt-free, audio, and LED alarm package included as standard
  • Compact, lightweight form factor — lighter than its predecessor
