Abstract: A pump control method for controlling at least one booster pump (4). The method includes switching on the booster pump when a booster pump outlet pressure (24) drops to a lower limit value (26), and switching off the booster pump when the booster pump outlet pressure (24) reaches an upper limit value (28). The lower limit value (26) is reduced in a case, in which the maximal outlet pressure (24a) which can be reached on operation of the booster pump (4) lies below the lower limit value (26). A pressure-boosting device is also provided with which the pump control method can be carried out.
