Abstract
Abstract A device for mixing two or more substances in which each substance is metered by a separate continuous-flow, positive displacement, volumetric gear pump, then forced together in a mixer manifold, then mixed to homogeneity by forcing through rotating ball, roller, or cone bearings. As an added feature of the invention, the mixer has a purge system permitting one-way flow of either solvent materials or washing materials into the mixer manifold, and a clutch assembly which allows the pumps to be disabled and thus non-delivering while the mixer is being purged. Another feature is valving to permit the introduction of catalysts or the like into the mixer manifold.
