A motor-pump assembly in a pumping station experiences severe vibration (may not be at resonance) when the motor operates at its normal operating speed of 2500 rpm. After a 1.5 kg un-damped absorber tuned to 2500 rpm is added to the part of the assembly, the system's new natural frequencies are measured as 2492 rpm and 2509 rpm.
