This paper presents determination of flow ripple conducted by two pressures/two systems methods in accordance with ISO 10767-1: 2015. The tests were done for an external gear pump with an involute profile without backlash. The tested pump had a technological error in involute tooth profile. On the recorded flow ripple, a negative peak is visible - an internal leak which is caused by a short-time gap formed during gears meshing. Such an error in involute tooth profile leads to rapid wear of the gear teeth surface, which has been presented.
