ABSTRACT:
The invention relates to a piston pump having a pump motor which has a motor shaft which merges into an eccentric for driving at least one pump piston. In order to support the eccentric in a robust manner, the motor shaft has ball bearings on either side of the eccentric, which ball bearings, in order to avoid alignment errors, are inserted into a common eccentric-bearing component. In order to be able to carry out a test run of the pump motor independently of a pump casing, the invention proposes to connect the eccentric-bearing component to a casing of the pump motor.
