摘要

Viscous fluid metering equipment has two material storage vessels, at least one (10) having two metering pumps (13,14) whose piston rods extend through a pressure tight seal (58) in the vessel cover (19) and connect in each case with a rack (23, 24). The racks are in a common housing (64) and are driven axially in opposite directions by a power unit (26). An Independent claim is also included for the process equipment.
