Drive mechanism for pumps, including a pump rotor mounted in a pump chamber, a pump cover covering the pump chamber. The cover has an axially projecting shoulder with a housing bore passing through from the pump rotor to the outside, and a shaft passing through the housing bore. The shaft is connected in a torsion-proof manner at its inner end to the pump rotor and at its outer end by way of a coupling element to a drive wheel. The shaft is supported in an inner bearing seated in the housing bore while the drive wheel is supported on an external bearing. A plate 7 is provided, which is separate from the pump cover 5 and which can be mounted on the housing or the like in various positions. The bearing 9 for the drive wheel 10 is supported on the plate 7 in a manner to allow freedom of rotation. |
