Volumetric displacement per dosing strokeThe stroke length adjustment limits the movement of the diaphragm. Adjusting the stroke length does nothave a linear proportional effect on the stroke volume. The volume per dosing stroke is derived from thedelivery characteristic curves or the delivery table on the dosing pump.To adjust, undo the lock screw, set the required value and retighten the lock screw.ATTENTION!Do not adjust stroke length while the pump is stationary but rather only during the delivery stroke.2. Stroke frequencyChanging the stroke frequency has a directly proportional effect on the flow rate. It is either set to a fixedvalue or defined by an external pulse generator (e.g. electronic controller or contact water meter).To ensure effective adaptation of the dosing pump to the respective process, the MAGDOS can be set todifferent stroke frequencies in internal mode.Operation | Operation & Maintenance Instructions | 17
