Abstract:
1. A chemical delivery system, comprising: at least a pair of manifold bodies linearly arranged to share a bulk fluid inlet and defining a bulk fluid flow path, wherein the bulk fluid flow path is fluidly interconnected to a dispensing fluid flow path in each manifold body, the dispensing fluid flow path defined between an eductor port and a valve port, the manifold bodies being fixedly coupled with a coupling tube that extends fully through the bulk fluid flow path, the coupling tube having a first end and a second end, wherein the first and second end each include an external tube thread such that tightening a coupling nut over the external tube thread at each of the first and second ends causes the manifold bodies to be sealing engaged, and wherein the coupling tube includes an internal tube thread at the first end for attaching a bulk fluid supply such that the bulk fluid supply enters the coupling tube and is directed into the bulk fluid flow path through a plurality of wall apertures in the coupling tube; and at least a pair of eductor assemblies, each eductor assembly including an eductor member and a valve assembly, the eductor member and valve assembly operably connected to the corresponding valve port and eductor port, each eductor member including a chemical inlet and a dispensing outlet wherein the valve assembly selectively directs the bulk fluid into the dispensing fluid flow path for drawing a chemical through the chemical inlet for mixing with the bulk fluid and dispensing through to a point of use through the dispensing outlet.
