The invention relates to a hand lever actuated pump (1) for delivery of fluid or paste-form media, comprising a pump chamber (10) which has an inlet valve (11) and an outlet valve (12), further comprising a pump piston (5) which cooperates with a pump cylinder (6), and comprising a cover base (72) for a withdrawal opening of a storage vessel, the cover base (72) being penetrated by a suction pipe (13), and comprising a return spring. In order to find a simplest possible structurally reliable construction, the invention proposes that the return spring abuts against the cover base (72) on the storage space side.
