The dispensing pump for dispensing metered amounts of paste-like or liquid substances from paste containers (41) is provided with a bellows (3) acting as a pumping member, which bellows are sealing arranged between two coaxial housing parts (1, 2), which are made of a dimensionally stable plastic and are telescopingly movable relative to one another. Suction and discharge valves (4, 5), designed as one-way valves with axially movable valve closing members (19, 32), are arranged at its two ends. A suction pipe socket (29), which is concentric to the suction valve and is directed toward the paste container (41), is located at a suction-side radial wall (12) of one /f the housing parts (2). To place the dispensing pump on replaceable substance containers with follower plunger and fitting closure in a simple manner, the housing part (2) connected to the suction-side end of the bellows (3) is provided, in one piece, with an enveloping body (40), which is open on the front side, for accommodating a filled paste container (41) with follower plunger (44) in an enveloping manner, and with an axially projecting opener plunger (58) on the suction side of the suction valve (4). In addition, the paste container (41) has, at a front wall (51), a collar (52), which projects against the suction valve (4) on the front side, sealingly surrounds the suction pipe socket (29), and has a disk- or pot-shaped cutoff closure (56), 7hich is connected to it in one piece via a thin, annular cutoff web (55) and can be separated from it by the opener plunger (58).
