This article deals with the testing of regulating and non-regulating hydraulic pumps in laboratory conditions. The laboratory test was carried out on the hydraulic device consisting of two separate hydraulic circuits (for testing the non-regulating hydraulic pump and regulating hydraulic pump). A throttle valve or proportional throttle valve is used for loading. During the laboratory tests, the flow efficiency of the non-regulating hydraulic pump at rotation speed <italic>n</italic> = 1,500 rpm (nominal speed) was η<italic>pp</italic> = 98.91% (0 MPa) and η<italic>pp</italic> = 94.97% (20 MPa), and for the regulating hydraulic pump, the values were η<italic>pp</italic> = 97.57% (0 MPa) and η<italic>pp</italic> = 94.54% (20 MPa). The determined values of flow efficiency of hydraulic pumps determine the correct operation of the experimental hydraulic laboratory equipment.

This article deals with the testing of regulating and non-regulating hydraulic pumps in laboratory conditions. The laboratory test was carried out on the hydraulic device consisting of two separate hydraulic circuits (for testing the non-regulating hydraulic pump and regulating hydraulic pump). A throttle valve or proportional throttle valve is used for loading. During the laboratory tests, the flow efficiency of the non-regulating hydraulic pump at rotation speed n = 1,500 rpm (nominal speed) was ηpp = 98.91% (0 MPa) and ηpp = 94.97% (20 MPa), and for the regulating hydraulic pump, the values were ηpp = 97.57% (0 MPa) and ηpp = 94.54% (20 MPa).
