ABSTRACT:
A barrel pump has a main pump pipe set comprising an outer housing jacket and a supporting pipe received therein for a rotor shaft. Either a carrier part with an individual sliding ring seal or a carrier part which corresponds in its outer dimensions to the carrier part and has a leakage channel for ascending liquid can be screwed onto the lower end of this main pump pipe set. The rotor shaft projects beyond this main pipe pump set. It is also possible for a carrier part with a leakage channel and a double sliding ring seal arranged in the region of the leakage channel to be screwed on. Due to their identical outer dimensions, the carrier parts are interchangeable. A pump base which encloses the pump rotor and is fastened to the lower end of the rotor shaft can be attached to the lower end of each carrier part.
