Critical speed | KSB

Critical speed (nk) is the rotational speed at which acting dynamic forces cause a machine component (e g shaft rotor) to vibrate at its natural frequency (also referred to as intrinsic frequency fi) and can even result in resonant vibrations throughout the entire machine and pump set This effect has the potential to damage fast rotating machinery but can be minimised when such rotational
