The development of hydraulic pumps and motors causes a high effort before series production can be reached. Design and manufacturing of all machine parts have to be done with high accuracy and carefulness.

The difficulties in the design process of hydraulic machines result from the high pressure forces acting in the rotating group of the hydraulic machines. These high forces have to be carried by small and oil filled gaps (the tribological contacts or tribological interfaces).

The general requirements of a hydraulic application needs different types of pumps (piston pumps, gear pumps, screw pumps etc.), different pressures and speeds and the fluid might need different properties and viscosities. Therefore, a good amount of knowledge and experience is required to design a hydraulic pump or motor. Especially knowledge in the areas of tribology, material sciences, general machine construction and on production technology are required.
