Abstract

Hydraulic pumps belong to the basic devices of each hydraulic system, because they convert mechanical energy to the pressure of the working fluid. As a significant number of drive solutions are realized by gear pumps, special attention will be dedicated to them in this paper. Their basic comparative advantage is in the simplicity of conservative solutions as well as relatively simple production. This implies, for the buyer, an acceptable price and not a negligible or favorable mass ratio and the achieved strength. For this reason, the authors of this paper will define all the indicators of this conclusion. In support of this assertion, we will analyze the gears of production of the famous Serbian manufacturer, PPT-HIDRAULIKA ad from Trstenik. The same will show tabs and diagrams.
