      Features

      1. The unit can keep water pressure stable, and you can adjust required pressure setting on the screen of inverter or PID.
      2. No water hammer. Improve start/off frequency. Smooth operation and low noise.
      3. The system will adjust motor speed automatically, according to demand of capacity that can save energy and uplift performance.
      4. Duplex pump with Dual inverter(VFD) alternating/ Parallel operation design. UN pump set is small that can be convenient transportation and save installation space.
      5. The SUS pipe/pump can be customized according to customer requirements to keep it does not rust.
      6. Provide constant water pressure while using water or hot shower.
      7. Low noise and smooth operation. The system will adjust motor speed automatically, according to demand of capacity. It can save energy resources and uplift performance.
      8. Dry-running detection. It will turn off automatically once no water occurs to avoid motor burn out.
      9. Adopting high quality brand “DELTA” inverter(VFD), high efficiency, softly start/off functions.
      10. Alternate & Parallel operation to extend life time of pumps.
      11. Major installation ways- One is installed the pump system in the top floor or roof of the building, auto-boost water pressure downward whole building. Another is installed the pump system on the ground or basement, auto-boost water pressure to (upward) the building.(Please refer to below Installation 1~2)

      Installation

      Without overhead storage water tank, UN pump directly auto-boost water pressure for the building.

      With overhead storage water tank, UN pump set is installed on the top floor. Auto-Boost water pressure downward.

      Applications

      Auto boosting water constant pressure for IC manufacture industries, industrial pressure boosting system of plant,Condominiums,Hotels, Motels, restaurants, gas stations, apartments, factories, schools, parks, gymnasiums, villas, railway station, building sites,shopping mall,military camp,..etc.

      The comparison between UN and UP Inverter(VFD) constant pressure pump systems: They have the same function, but the UN is more compact and lighter. It’s perfect for places where installation space is limited, saving transportation space and making installation easier.
