The device dedicated to the pressure loading of hydrostatic pump was designed for the test of new biodegradable hydraulic fluid type ERTTO made by Slovnaft a.s. member of MOL group. The device can load the used type of hydrostatic pump by the cyclic pressure loading. The used hydrostatic pump was gear hydrostatic pump type UD 25 made by company Jihostroj a. s. This type of hydrostatic pump is using in the newest types of tractors Zetor Forterra. The device was designed and assembled with using of elementary components to realize test of biodegradable fluid under high reliability and low demands on maintenance and service during the test.
