DG PED is an automatic pressurisation system with inverter which integrates:

• a high efficiency self-priming pump
• an expansion vessel
• pressure and flow rate sensors
• a non-return valve.

DG PED is a compact, autonomous, quiet and high performance
pumping system.

A sophisticated electronically controlled inverter, at the heart of the system, in an intuitive way:

• maintains the pressure of the installation constant by regulating the
  speed of the pump in accordance with the required flow rate
• controls the hydraulic and electric operating parameters and protects
  the pump from anomalies
• can be equipped with an expansion card that makes it possible
  to work in parallel with other inverters in the pumping groups by
  managing input and output signals
• it adapts to every type of pressurisation system, including existing
  ones
• it limits the starting and operating currents in order to provide a
  greater saving of energy.
