Pressure compensated Venturi dispensing system

A method of assembling a dispensing system, the method comprising:

• obtaining an eductor including an inlet port, a pickup port, and a discharge port;
• coupling the inlet port to a source of a diluent;
• coupling the pickup port to a source of a chemical product;
• coupling the discharge port to an upstream chamber of a check valve;
• and
• coupling a downstream chamber of the check valve to one intake port among a plurality of intake ports of a flush manifold, and
• wherein the eductor is configured to draw the chemical product into the eductor in response to the diluent being flowed through the inlet port such that the chemical product is mixed with the diluent to form a chemical solution.

A dispensing system comprising:

• an inlet manifold comprising an inlet port and a plurality of outlet ports wherein the inlet port of the inlet manifold is fluidically coupled to a source of a diluent;
• a plurality of eductors, each eductor comprising an inlet port, a pickup port, a discharge port, and a venturi fluidically coupled to each of the inlet port, the pickup port, and the discharge port, wherein the inlet port of each eductor is fluidically coupled to one of the outlet ports of the inlet manifold, the pickup port of each eductor is fluidically coupled to a feed line from one of a plurality of sources of chemical products, and the venturi of each eductor being configured to draw the chemical product into the eductor in response to a flow of the diluent from the inlet manifold to the inlet port such that the chemical product is mixed with the diluent to form a chemical solution;
• a flush manifold comprising a plurality of intake ports;
• and
• at least one check valve fluidically coupling the discharge port of at least one eductor of the plurality of eductors to one of the intake ports of the flush manifold.
