1)These values are valid at:- an absolute pressure of pabs=1bar at suction portS- for the optimum viscosity range from vopt=36 to 16mm2/s- with hydraulic fluid based on mineral oils2)Maximum speed (limiting speed) with increased inlet pressure pabsat suction portS, see the following diagram.3)Torque without radial force, with radial force see table "Permissible radial and axial forces of the drive shafts"
