Pressure expansion vessels for drinking water distribution and pumping systems

The pressure vessels collect the pressurized water from the pumping systems and play the role of a hydrodynamic flywheel during the extraction phases.

This feature helps to significantly reduce the frequency of restarting the pumping unit, thereby improving the overall energy efficiency of the system.
A pressure switch constantly regulates the pressure in the circuit and activates the pump only when the water in the pressure vessel reaches a pressure below the minimum required threshold.

When switched on again, the pump fills the pressure vessel again until a set maximum pressure is reached.
