A dispensing pump (1) made of plastic for dispensing metered amounts of paste-like media includes a bottle-, can- or tube-like container (60), with an elastic bellows (4) acting as a pumping member, which is connectingly arranged between an upper housing part (2) and a telescopingly movable, lower h
A dispensing pump (1) made of plastic for dispensing metered amounts of paste-like media includes a bottle-, can- or tube-like container (60), with an elastic bellows (4) acting as a pumping member, which is connectingly arranged between an upper housing part (2) and a telescopingly movable, lower housing part (3), which is coaxial thereto, and whose interior (32) forms a pump chamber. Its upper end section (38) is connected to an annular wall (35) of the upper housing part (2). Its lower end section (45) is in sealing contact with an annular shoulder (46) of a radial partition (19) of the lower housing part (3). A second pump chamber (33, 33/1 ) for a second medium, which communicates with the discharge opening (10) of the upper housing part through a second discharge valve and/or at least one flow opening (34) in the partition (13), is formed by two annular wall sockets (30, 31 ), which are telescopingly guided one inside the other, concentrically surround the bellows (4) at a radially spaced location, and are made in one piece with one of the two housing parts (2, 3) each. On the suction side, the second pump chamber is connected to an annular chamber (81) of a container (61) or to a second container via at least one eccentric suction channel (82) in the radial wall (19).
