Abstract: The efficiency improvement of Internal Combustion Engines (ICEs) is still necessary, providing them a valid contribution to the future of road propulsion, increasingly governed by regulations aimed at curbing CO2 emissions. In this context, technologies related to engine thermal management, and more specifically to the cooling pump, offer a good potential. Screw-type cooling pumps, notably triple-screw pumps (TSP), emerge as a solution, demonstrating superior efficiency compared to centrifugal pumps at design and off-design operating conditions.
