The article presents the results of preliminary experimental tests focused on pressure pulsations of gear pump type PGP511 with the inverter-fed drive. The obtained results were compared with the pressure pulsation of the examined gear pump powered in a conventional way. A cycle of measurements was carried out for variable hydraulic resistance and fixed temperature of hydraulic fluid. The obtained results were analyzed in time and frequency domains.
