The self-oscillations (surging) of a single-stage centrifugal pump working in a hydraulic system in the cavitation regime before the stall of the water feed were investigated. The character of change in these oscillations with change in the value of the acoustic capacitance positioned at the input of the pump was determined. The damping of the indicated self-oscillations with the use of an acoustic liquid damper connected to the hydraulic system was investigated. The impossibility of realization of a model of cavitation self-oscillations for a single-stage impeller pump was substantiated.
