The volume flow metering of the Universal Chemical Pump UCP detects and measures the
volume flow rate at the set delivery pressure. The switching points are hidden from the
measurement and mathematically added to the measurement results. The delivery pressure at the
switching points is kept constant by activating the second piston for material delivery before the
first piston enters the suction stroke.
This principle generates a pulsion-free supply flow that is regulated by material pressure
only.The volume flow metering is measured volumetrically under real conditions.

Controlling the compressed driving air ensures an exact pressure in the dosing line of the fluid to
be delivered and also determines the size of the volume flow rate.
