Erosion wear is a serious problem that constantly accompanies the operation of the system for hydraulic transportation of solid materials. The consequences are the loss of material (steel), loss of work element’s working capacity, great operational expenses, etc. The choice of new materials for working elements, improvements in construction, and optimization of the slurry flow are all various ways of softening the consequences of erosion wear that reflects on the working life of the hydraulic transportation pump’s elements. Data, which would be used for acquiring the above mentioned goals, are mainly acquired through testing in laboratory or semi industrial conditions. It has been proved that numerous influential and time effected values, complex and long term research, etc., make this job an expensive one, and the results are often solely applicable to specific operating conditions. To resolve this problem, the author suggests a combined approach: shorthand experimental researches and mathematical modeling of erosion wear. The suggested model, used for defining the mass loss of the working element affected by solid particles in the slurry, offers the possibility of introducing a greater number of influential values, some of which have a coincidental character. Through the realization of this model, wear intensity data is acquired, which are practically noncoincidental values with a great degree of reliability, and which greatly coincide with the results acquired through measurements conducted on the test facility.
