Abstract

A metering pump comprises a drive unit (1) and a pump head (11), into and from which fluid which is to be metered can be sucked from an input line via a first non-return valve (17) or can be expelled to an output line (20) via a second non-return valve (19). The drive unit comprises a control organ (2) which, on the basis of electrical control signals, controls a force-applying fluid or an actuating flow inside the drive unit so as to regulate movements of the pump. The pump head comprises a working space (16) and an expulsion organ (12) capable of interacting with the fluid which has been sucked into the space, said expulsion organ in the course of a space-reducing movement in the pump head expelling the sucked-in fluid into the output line. Part of the total space-reducing movement of the expulsion organ is reserved for compressing the fluid sucked into the space before the expulsion movement begins. At the metering of fluid including gas bubbles, the metering pump makes accurate metering processes possible.
