Abstract: Sliding Rotary Vane Pumps (SVRPs) are real candidates to replace the conventional centrifugal machines for engine cooling systems. Differently from the centrifugal pumps, SVRP performances are theoretically independent from the operating conditions, preventing in this way a lower efficiency when the machines work far from the design point. To achieve these benefits, however, the SVRP should be properly designed especially in those applications characterized by high flow rate of coolant delivered as in the case of heavy-duty engine cooling systems. A common design approach is the increase of flow rates pushing SVRPs to operate with high speeds of revolution, aiming to minimize the pump dimensions for space and weight constraints on board. Nevertheless, friction power lost is recognized as the main limit of this positive displacement technology and grows with revolution speed. Hence, SVRPs employed in cooling systems of heavy-duty internal combustion engines (ICEs) are particularly critical from this point of view.
