Abstract: 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).
