Nocchi EasyBoost

Summary

Product Identification

The Nocchi EASYBOOST units are compact, robust, and reliable systems designed for automatic pressure boosting in water distribution networks. Each unit comprises:

• 2 electric pumps
• Electrical panel
• Base
• Suction and delivery manifolds
• Pressure switches
• Pressure gauge
• Delivery check valve

The pumps are controlled by two adjustable pressure switches connected to an electronic board, enabling sequential start-up, inversion of start-up sequence, dry-running protection, and timer settings.

  • Manual/Automatic mode indicator LEDs
  • BMS with contacts for each pump indicating pump running and pump overload.
• Signals and Controls (Three Phase Electrical Panel):
  • M-0-T button (Manual - 0 - Automatic)
  • ON/OFF buttons for each pump
  • Power ON indicator LED
  • Pump running indicator LED
  • Indicator LED to signal low level in tank on first collection or low pressure on suction manifold.
  • Overload indicator LED
  • Manual/Automatic mode indicator LEDs
  • BMS with contacts for each pump indicating pump running, pump overload, and water supply failure.
  • RS232/RS485 communication.
