This article is devoted to a numerical study of the pulsation perfor-mance of a gear pump in the Ansys CFX software package in 2D. The article presents numerical data of a prototype pump and an upgraded pump with the same specific performance. The distinctive features of the latter are a different number of teeth and a different width of the gear wheel, as well as the presence of discharge grooves.The results of calculations show the effectiveness of the proposed upgrades.  Recommen-dations for the design of low-consumption pumps are offered.
