A laboratory pump (1) for liquids has a pump housing (2) with an inlet opening (3) and an outlet opening (4) and in which at least one pump rotor (5) rotates. The pump rotor (5) is joined either directly or indirectly by means of a transmission with a magnet (6), which is magnetically coupled with a rotating magnetic field of a magnetic stirrer (8). In addition, the pump housing (2) of the pump (1) can be joined with the magnetic stirrer (8) in such a way that the magnet (6) comes under the influence range of the rotating magnetic field of the magnetic stirrer (8) and is driven by it. The pump has no driving means of its own, and therefore can be designed in an especially simple way. Magnetic stirrers (8) present in laboratories can be used for driving the pump (1), and thus obtain an additional function.
