HDLV Pump Manifold Components

The Prodigy High-Density powder, Low-Volume air (HDLV) powder feed
pump transports precise amounts of powder from a feed source to a powder
spray gun. The pump manifold controls the pump air and vacuum flow. The
pump control board controls all manifold functions.
Table 2-1 Manifold Components
Control the air flow to the pump during operation.
NOTE: Refer to Solenoid and Control Valve Functions on
page 5-3 to identify each valve's specific function.
Regulates the air pressure to the spray gun's nozzle, which
shapes the powder spray pattern.
Regulates the positive air pressure to the fluidizing tubes,
which dispenses the powder out of the tubes.
Turns the airflow through the vacuum generator on or off.
Works on the Venturi principle to generate the negative air
pressure required to draw powder into the fluidizing tubes.
