The article presents the values of the failure rate for modern types of pumps of four groups: submersible, designed for drainage and wastewater drainage; domestic; cantilever; submersible - for artesian water intake based on statistical data processing on their operation. The obtained values of the failure rate allow us to evaluate the reliability indicators of hydraulic circuits that use various types of pumping equipment. The article analyzes the failures of pumping equipment with their detailed description and presentation of practical photos accumulated at a specialized enterprise, whose activities are aimed at designing pumping stations, supply, installation and maintenance of pumping equipment on the territory of the Republic of Crimea.
