The dyes are drawn from the Supplier's drums and are then metered in controlled volumes. The specific blend of dyes is obtained by setting the plunger stroke length of each pumphead. The dye volume is adapted to the stock flow by varying the speed or stroking speed of the pump. The flow of dilution water is adjusted by means of a flow meter and a control valve. The metered dye and water volume are blended in a static inline mixer and are added to the dilution stock upstream of the paper mill.

The suction line of any pumphead can be filled and made ready for operation by switching over the three-way valve and water driven ejector, even while one of the dye metering pumpheads is still working. The Bran+Luebbe building block system provides a metering pump unit with up to 36 pumpheads for different dyes. Flushing of the metering and blending system is obtained via three way valves.
