Pulsation dampener
Easy dosing with large pressure fluctuations
Failure to take into account the typical acceleration and delay of the media conveyed by the dosing pumps can result in considerable faults. Too great an acceleration on the suction side can result in cavitation and thus the stoppage of the suction flow. Long lines on the supply side can experiences large forces which can damage the dosing pump. Damaging vibrations in the pipe line can cause destruction. This can result in unpleasant noises. Order a flow meter to ensure good functioning in relation to equal flow. Additional work is required before the float flow meter can be installed on the discharge side of the dosing pumps, as the float would rise and fall violently.
