We studied the distribution of losses in the blading section of the pump and designed runners and diverters. We computed operating fluid flow parameters in a rotary vane pump with a low suction specific speed by means of hydrodynamic modelling. For this purpose we designed a 3D model of the blading section found in a pump with a low suction specific speed and computed the flow in it for a wide range of operating fluid viscosities.
