ABSTRACT:
The discharge pipes of a plurality of stock pumps, each supplying a separate concentrated stock slurry, are connected with a pipe containing comparatively dilute stock, commonly called "white water", discharged under pressure from a single fan pump on a single white water silo to supply separate slurries to separate chambers of a multi-ply web forming machine. The stock pumps have smaller capacities and pressure heads compared with a fan pump, thereby providing increased efficiency at required capacity with the minimum of equipment.
