Abstract: The paper presents the applied methods of testing, observations, problems and experiences gained during the development of a domestic high pressure pump at the Military Technical Institute, which can be of interest and benefit to the wider professional public. The pumps are intended and specially designed for diesel engines, with the nominal power of up to 1000 hp, and are produced in many varieties, in our country and abroad, in large number. The development of this pump proved to be very important, as the foreign business partner cancelled the contracted cooperation in the production and delivery of serial engines high-pressure pumps. Problems got even more complicated when the domestic manufacturer, after the ownership transformation, gave up the    further cooperation on the almost agreed production of the domestic pump. In the last five years, efforts have been made to enable a domestic manufacturer to produce the pumps. Although it is a company that has never previously dealt with the development and production of such mechanical and hydraulic systems, the achieved results in production and the experience gained so far give real hope that the mutual efforts will reach the required quality and create a competitive product.
