Gianneschi Pressurized Water Systems w/ Variable Speed Drive
The pumps are powered by a variable frequency drive in order to maintain the pressure whatever the demand.

Control Pump Series

The pumps are powered by a variable frequency drive. It is in fact an inverter with variable frequency and voltage control (constant U/f ratio).

The drive adjusts the speed rotation of the motors according to the pressure measured by the transducer, in order to maintain the pressure whatever the demand.

On dual pump systems, the pump are started in sequence (as a backup for one another), following programmable thresholds.

Applications:

  • Constant pressure water supply.
  • Flow control.
  • Water level control.

2 x ACB 431 2 x 200 L/min 4 bar 2 x 3 kW
2 x ACM 312 2 x 140 L/min 5.5 bar 2 x 3 kW
2 x ACM 402 2 x 200 L/min 6 bar 2 x 7,5 kW
2 x ACM 502 2 x 360 L/min 7 bar 2 x 9,2 kW

Other models available on request. We can help you define your application requirements.

Features:

  • Run dry protection: the system automatically shuts down if pressure is too low, to protect the pump against being run dry.
  • Overload protection: the motors are stopped when the pumps are running out of their nominal characteristics.
  • High efficiency: power is adjusted to match demand.
  • Adjustable regulation (PID control).
  • Constant monitoring of the pressure transducer.
  • Automatic reset: when activated, this function enables to reset an alarm for an automatic restart once the problem has been solved.
  • Programmable duty cycles to balance cumulative run time for each pump.
  • Inputs for remote control devices.
  • Outputs for remote alarm devices.
  • Electric switchboard with built-in control panel, circuit breaker, fuses and main filter.
  • Voltage: 230/400 V or 230 V (50 Hz or 60 Hz).
  • Vertical or horizontal configuration.
