  • the pump head 22 has a pressure chamber 39 connected downstream of the outlet valve 26, which is delimited by a control membrane 40 arranged in the plane of the membrane 23.
  • the control membrane 40 interacts with an actuator 72 of a pressure switch 71, by means of which the switching point of the drive motor 51 can be set as a function of the delivery pressure in the pressure line 37.
  • a shaded-pole motor is provided as the drive motor 51, which acts on the connecting rod 62 via a toothed belt drive 57.
