Single-stage cantilever centrifugal pump rotor dynamic balance

The customer requested that the rotor be dynamically balanced, but the workshop operators stated that it is only possible to add weight to one side of the impeller, and dynamic balancing cannot be carried out. What’s going on? Is this really the case? Experienced friends, please discuss this @Foam_ZPTK
If it can be ensured that your equipment operates smoothly with vibrations within acceptable limits, then there’s no need to take any action. It’s reasonable to say that it’s not necessary: lol. Performing dynamic balancing is not just a way to reduce weight; it can also be used to increase weight. For large equipment or those with special requirements, solutions can also be found regarding the shaft diameter.
Dynamic balancing can be carried out if the two calibration surfaces can be separated on the balancing machine. Unable to separate, only static balance is possible
