The oscillator pump (1) has a housing (2) with a disk (4), forming at least one ring zone (6) in the radial direction between the disk and the housing. It is separated into chambers (8) in the peripheral direction by a divider (7) mounted to the housing and/or disk. The housing or the disk is oscillated by the drive, keyed against rotation around it axis, to alter the chamber volumes at a suction or pressure side of the pump. The disk is a ring disk, oscillating against the housing. An outer ring (14) is around the disk holding it, with a cover. The chambers are divided along the peripheral direction to set the pressure pulsation spectrum for the required noise and/or pumping characteristics.
