Abstract

A fluid application system includes a diluent reservoir, a chemical container, a sprayer housing, a manifold located in the sprayer housing, and a pump assembly in fluid communication with an outlet of the manifold. The manifold includes a diluent inlet in fluid communication with the diluent reservoir, a chemical inlet in fluid communication with the container, a mixing chamber in fluid communication with the diluent inlet and the chemical inlet and the outlet of the manifold. The pump assembly draws a mixture of the chemical and the diluent from the manifold and sprays the mixture of the chemical and the diluent from the nozzle.
