In a previous paper the authors have dealt with the calculation of the pressure loads on the rotors of a three screw pump. The pressure loads can be modelled as a force and a moment. In particular, starting from the knowledge of rotor geometry, the loads can be calculated and subdivided into their components along the screw axes. In this paper the simulation results obtained by using the proposed model are presented. The results show that the satellite screws are thrust towards the case in a specified direction. This fact can be verified in practice, since the cases actually present a wear zone in a particular position.
