The Encore Generation II powder feed pump is a venturi-type pump that
supplies organic and metallic powder coatings to powder spray guns. It is
available in two versions, Corona and Tribo. The Corona version has two
quick-disconnect fittings for flow-rate and atomizing air, while the Tribo
version has only one fitting for flow-rate air.
Flow-rate air lifts fluidized powder from a vibratory box feed or a feed
hopper and forces the powder through the powder hose to the spray guns.
Atomizing air dilutes and atomizes the powder stream, and increases its
velocity, as it exits the pump.
