PROBLEM TO BE SOLVED: To provide a pump having a rotor taking a balance by a method further improved, and to provide the method for taking a balance of the rotor.SOLUTION: A pump is, in particular, a vacuum pump, and has a rotor (1) rotatable around a rotating shaft (14), the rotor (1) has an adjustment region for at least one balance weight (7), here, a clearance to the rotating shaft (14), of the balance weight (7) is adjusted to one target clearance (R) among a plurality of target clearances determined on the rotor (1), and a desired balance state is realized in the target clearance with the adjusted balance weight (7). |
