• Base
• Intake and delivery manifolds
• Pressure switches
• Pressure gauge
• Check valve in supply

Operating limits

The booster sets are available with different pump configurations, leading to varying performance characteristics.

• Maximum Capacity:
  • CB: 16.8 m³/h
  • DHR: 28.8 m³/h
  • MULTINOX VE+: 25.2 m³/h
  • PVM: 17 m³/h
• Maximum Head:
  • CB: 60.5 m.c.a.
  • DHR: 63 m.c.a.
  • MULTINOX VE+: 140 m.c.a.
  • PVM: 110 m.c.a.
• Maximum Operating Pressure:
  • CB: 9 bar
  • DHR: 10 bar
  • MULTINOX VE+: 14 bar
  • PVM: 16 bar
• Ambient Temperature:
  • CB: 40° C
  • DHR: 50° C
  • MULTINOX VE+: 50° C
  • PVM: 50° C

General maximum capacity range for the booster sets is from 200 to 480 L/min (12 to 28.8 m³/h).

Electrical

• Power Supply: 1 ~ 230 V or 3 ~ 400 V
• Frequency: 50 Hz
• Degree of Protection:
  • Control Panel: IP55 or IP54 (model dependent)
  • Pump: IP44 or IP55 (model dependent)

Electrical Panel (Single Phase)

• Box in plastic material IP65
• Fuses
• Multifunctional electronic board with integrated transformer for the auxiliary circuit
• Start-up relay for each pump
• Protection against overload provided by the electronic board
• Trimmer to adjust the delay time from 0 to 180 seconds, after the opening of the contact of the pressure switch (for each pump)

Electrical Panel (Three Phase)

• Metal box IP54
• Main switch
• Electronic board
• Fuses and contactors for each pump
• Protection against overload provided by the electronic board
• Transformer with fuses for the auxiliary circuit

Main Functions

• Cyclic inversion of the start-up order of the pumps after each cycle end.
• ON/OFF control of the level of the tank or the pressure of the supply duct by means of a float switch or a different differential pressure switch.
• Adjustable timer for the pumps (single-phase) / Timer of the last pump settable from 0 to 180 seconds, after the opening of the pressure switch operation contact (three-phase).

Signals and Controls

• Manual - Automatic button (single-phase) / M-0-T button (Manual - 0 - Automatic) (three-phase)
• ON/OFF buttons for each pump
• LED indicating the presence of power
• LED indicating pump in operation
• LED indicating low level in the collection tank or pressure insufficient in the Suction manifold
• LEDs indicating manual or automatic operation
• BMS with contacts for each pump: pump on and overload (single-phase)
• BMS with contacts for each pump: pump on, overload and no water alarm (three-phase)
• Communication RS232/RS485 (three-phase)

External Control Devices

• Two adjustable differential pressure switches ON/OFF
• ON/OFF float switch, located in the water collection tank, or
• Reverse pressure switch inserted in the water supply duct (aqueduct)
