Experimental test bench for performance-assessment of large submersible and dry-action pumps used in waterways

Pumping in waterways, particularly in artificial canals, is energy-intensive, costly and may be responsible for the emission of large quantities of CO2. Innovative pumping technologies have the potential to reduce energy consumption; but their performance needs to be thoroughly as-sessed. This communication presents the design, sizing and construction of an experimental test bench for evaluating the performance of large submersible and dry-action centrifugal pumps typically used in waterways. It enables testing prototype-scale pumps and was designed in close collaboration with stakeholders such as canal operators. This experimental facility is challeng-ing on many aspects given its size, as well as requirements for power supply and for measure-ment of system efficiency.
