The present invention relates to a tester for testing the performance of various hydraulic pumps widely used in various industrial fields.;The conventional hydraulic pump performance tester was a method of manually controlling the pressure and verifying the performance by installing the measuring means and the relief valve sequentially in the hydraulic line. However, in order to solve this problem, there is a lot of time loss in manually setting the appropriate pressure for the experiment under various pressure ranges from 0 to 400 bar.;It is also possible to quickly change the pressure of the hydraulic piping through which the hydraulic fluid is flowing through the high-speed on / off valve sequence control using the sequence control unit by adding an accumulator, a high-speed on / off valve, a relief valve, .;The present invention prevents the reliability of the experimental data measured by the measuring means from being reduced due to the pressure fluctuation phenomenon that occurs each time the experimental stage is changed by using the accumulator, and the reliability of the experimental data measured by the high speed on / off valve, relief valve, It is possible to reliably measure the hydraulic pump while varying the various hydraulic pressures.
