Pedrollo DG PED Automatic Pressurisation System with Inverter – 230V

The Pedrollo DG PED is an automatic pressurisation system with a built-in inverter, delivering constant water pressure that adjusts pump speed to match demand rather than cycling on and off at fixed speed. The pressure set point is adjustable between 1 and 5.5 bar (shipped set to 3 bar), so the system can be tuned to the household or system it's installed on. Available in single-phase 230V.

• Application: Domestic and small commercial constant-pressure water supply.
• Motor: Single-phase 230V.
• Power range: 0.75kW (1HP) to 1.1kW (1.5HP).
• Performance: Max flow 80–120 L/min, max head 55m, depending on model.
• Pressure control: Adjustable set point from 1 bar to 5.5 bar, standard setting 3 bar.
• Motor efficiency: IE3 motor class, per IEC 60034-30-1.

Key Features

• Inverter-driven constant pressure: Automatically varies pump speed to hold a set pressure, rather than the on/off cycling of a standard pressure switch pump.
• Adjustable set point: Tune the working pressure anywhere from 1 bar to 5.5 bar to suit your system, rather than being locked to one fixed pressure.
• Two size options: DG PED 3 for smaller systems, DG PED 5 for higher flow demand.

Typical Applications

• Domestic water supply where consistent pressure is wanted regardless of how many outlets are open
• Small commercial systems needing constant pressure
• Replacing a standard pressure-switch pump where pressure fluctuation is a problem

Technical Specifications

Performance figures are read from the manufacturer's official performance chart. At the minimum 1 bar set point, DG PED 3 delivers 35–80 L/min and DG PED 5 delivers 50–120 L/min; at the maximum 5.5 bar set point, DG PED 3 delivers 5–30 L/min and DG PED 5 delivers 5–50 L/min.
