It is possible to selectively also slow the suction stroke with all these
metering profiles for the discharge stroke - see . In this way, it is possible
to prevent the main cause of inaccurate metering with high viscosity feed
chemicals, namely the incomplete filling of the liquid end. With gaseous
feed chemicals, the slow suction stroke prevents cavitation and conse‐
quently increases dosing precision.
