Headlosses. For the above reasons the headlosses of a distributor are quantifiable in a difficult way. The diagrams show approximately the headlosses of the range of distributors HV 60 and HV 70 (draw. 1) and of the hydraulic switcher HW 60 (draw. 2).

MAX: the straight line shows the conditon of maximum headloss of each pump unit, corresponding to the the estreme working conditions of the distributor. MIN: the straight line shows the conditon of minimum headloss of each pump unit, corresponding to the average working conditions of the distributor. The surface between the two curves shows approximately the range of the headlosses in the different working conditions. |

Thanks to the hydraulic switcher the flows on the primary and on the secondary circuit are not necessarily the same. Please refer to the flows of the following table:
| Model of distributor |
Model of hydraulic switcher |
Flow of the primary circuit reccomended / maximum |
Total maximum flow of the secondary circuit |
| HV 60/125 (1”) | HW 60/125-04 (1”) | 2000 l/h / 4000 l/h | 4000 l/h |
| HV 70/125 (1”1/4) | HW 60/125-05 (1”1/4) | 3000 l/h / 5000 l/h | 5000 l/h |
