SizingHydro 2000Example: How to select a system• A head of 45 m is required.The pump type best meeting this specification isfound by means of the y-axis, e.g. CR 10-6.Draw a rightward, horizontal line from the head required.• A flow of 18 m 3 /h is required.Now draw an upward, vertical line from the specifiedflow. The intersection of the two lines gives thenumber of pumps required for the system (2 CR 10-6).Only systems whose operating ranges lie within thehatched area of the example should be selected.p[kPa]900800700600H[m]90807060Hydro 2000CR 10-9MS-MSH50 HzISO 9906 Annex A500501 2 3 4 5 640040CR 5-14300p[kPa]70030H[m]70CR 10-6MS-MSH60060500504004030030CR 5-101 2 3 4 5 6200p[kPa]50020H[m]50CR 10-4MS-MSH40040300302001000p[kPa]30020100H[m]30CR 5-8 1 2 3 4 5 6CR 10-3MS-MSH2002010010CR 5-51 2 3 4 5 6000 5 10 15 20 25 30 35 40 45 50 55 60 65 70 75 Q [m³/h]0 2 4 6 8 10 12 14 16 18 20 Q [l/s]TM02 7578 380319
