Throttle control

The throttle control is suitable for changing the operating point of a centrifugal pump system. A throttling device in the pressure line of the system changes the dynamic portion of the system characteristic curve. A new head is created that is significantly above the required head. The difference is destroyed by dissipation in the throttling device. This results in altogether higher operating costs, because the pump is operated further away from the best efficiency point and with a low efficiency. This type of pump control is no longer up to date due to the high pressure losses. (see speed control)
