The report presents the results of research on the use of composite material - fiber-reinforced concrete for the manufacture of centrifugal pump bodies. The, optimal composition of fiber-reinforced concrete with the required strength characteristics has been established. The method of casting a pump body and the results of industrial tests to determine the technological parameters of a centrifugal pump are presented. The results obtained showed that fiber-reinforced concrete bodies have an advantage over metal ones and can be recommended for use in mechanical engineering in the manufacture of centrifugal pump bodies.

Efficiency of application of fiber concrete as a material for manufacturing bodies of centrifugal pumps
