Abstract:
1. An apparatus for paint powder transportation between a first location and an application point comprising: a first powder hopper having a plurality of individual hopper outlets; a first pair of transfer pumps, one of each of the first pair of transfer pumps coupled to a different one of the plurality of individual hopper outlets for transferring powder from the first powder hopper in separate powder flow paths; a first pair of final dense phase pumps for transferring powder to two application location powder applicators; a first cross-feed network formed of a plurality of multi-directional valves including a first pair of inlet valves coupled in paint powder flow to one of the first pair of transfer pumps, and a pair of outlet valves, each coupled in paint powder flow to one of the first pair of final dense phase pumps, each inlet valve having two outlets, each outlet separately and non-parallely coupled to one inlet of both of the pair of outlet valves, whereby control of the inlet and outlet valves allows powder to be transferred from the first powder hopper by either one of the first pair of transfer pumps through the first cross-feed network to either one of the first pair of final dense phase pumps.
