Morphological matrix are considered one of the most powerful, advanced, resources, tools, methods of structuring, classification, combination, evaluation and selection of information used in science and technology, with application in the development of new products. In this paper a particularisation of this method is presented for the development of technical solution for hydraulic pump unit used in oil extraction. The proposed methodology uses three stages: 1. listing and codification of elements forming assemblies, 2. listing of morphological matrix; 3. application of a decision method and determining the optimal solution. Particularly important is the analysis of the current state of knowledge in the field, where in the case approached, patent databases were used extensively. By morphological matrix approach is desired to discover new products, superior technical and economic characteristics.
