These Dosing or Metering Pumps (oscillating positive displacement pumps) suck in a defined fluid volume with the backstroke of the displacer and press it into the dosing line with the pressure stroke. Adjusting the stroke volume and the dosing strokes per time unit can regulate the metering capacity.
