Purpose: to develop new designs of pumping equipment with the elimination of the causes of wear and failure of the working parts of vane pumps. The new calculations of the dynamics of change in the availability coefficient, the failure rate and recovery in a given time interval of the impeller with improved flow part and pump parts are proposed.

Materials and methods. standard methods of mathematical and hydraulic modeling were applied, their numerical solution with clarification of the calculation method of technological processes in pumps by changing the number of impeller blades, the angles of flow inlet and outlet.

Results. The need of solving the problem of water supply control at pumping stations in reclamation and water management complexes using methods that allow taking into account the dynamic characteristics of processes during pump operation is substantiated. Pump performance depends on the shape of the impeller blade cross-section, their angle of inclination and quantity.

Conclusions. The design of new elements based on the calculation of a flow limited only by the side walls is proposed. The units were developed based on the results of a large number of pump tests and operational surveys of irrigation pumping stations conducted by the authors. The determination of the economically feasible duration of the operating period of pumping units, taking into account changes in the pump condition and the dynamics of changes in the availability coefficient, was clarified by measuring the efficiency of the modernized pumps. The modernization of the pumps made it possible to achieve higher efficiency by 3–4 % and an increase in service life, which reduced repair costs at KMK by 18–26 %.
