Abstract:
A process for transporting and pressurizing flowable reaction components of a reaction mixture from at least one storage container to at least one mixing head, comprising the steps of:(a) providing at least a first gear pump, a second gear pump, and a third gear pump, the first, second and third gear pumps having the same rotary speed of up to about 800 rpm. (b) connecting the first gear pump to the second gear pump by a first pipeline then connecting the second gear pump to the third gear pump by a second pipeline; (c) transporting the flowable reaction components, at least one of the flowable reaction components comprising filling material, to the first gear pump, then through the first pipeline to the second gear pump, then through the second pipeline to the third gear pump; and (d) providing pressure on the flowable reaction components in stages.
