Abstract:

The invention is a compact, self-contained, portable, electrically powered, knockdown spray application machine/system for spraying liquid material on to surfaces. The spray system comprises a frame with wheels for supporting and transporting the components thereof. The spray system is powered by an electrically activated motor which includes a motor drive shaft disposed about a motor drive shaft axis. Attached to the motor is a gear reducer having a driven end and a drive end wherein the driven end is configured to receive and engage the motor drive shaft. The drive end includes a gear reducer drive shaft that rotates responsive to electrical activation of the motor. Coupled directly to the drive end of the gear reducer is a pump comprising a pump housing. The pump housing is shaped to define a containment chamber for receiving and containing liquid material therein. The pump housing also defines an inlet port for receiving and directing liquid material into the containment chamber.
