Pressure boosting device

A pressure boosting device for increasing the pressure of a fluid flowing through a conduit, the device comprising:

• at least one booster pump;
• a control device configured to control the booster pump;
• and
• at least one pressure sensor arranged at an exit side of the booster pump, the at least one pressure sensor being connected to the control device, wherein the control device is configured to, in one operating region, control the booster pump in a start-stop operation including switching off the booster pump upon reaching an upper pressure limit value and switching on the booster pump upon reaching a lower pressure limit value, and the control device is configured to, in the start-stop operation, automatically adapt the upper pressure limit value or the lower pressure limit value or both the upper pressure limit value and the lower pressure limit value or a pressure difference between the upper and lower pressure limit value, and
• wherein the control device is configured to effect the adaptation of the upper pressure limit value or the lower pressure limit value or both the upper pressure limit value and the lower pressure limit value or the pressure difference between the upper and lower pressure limit value based on a temporal course of at least one detected pressure value in evaluation time periods, in which a constant flow prevails in the conduit, based on pressure input provided by the pressure sensor.
