Air Flow Settings for Venturi Pumps
Powder output from venturi pumps is controlled by flow-rate and atomizing
air flow.
S
Flow-rate air
controls the amount of powder pumped.
S
Atomizing air
diffuses the powder flow for an even spray pattern.
Typically, the flow settings are determined by switching the gun mode to
Manual, triggering the gun, and adjusting the air flows while observing the
spray pattern and bagging and weighing the powder. Optimum air flows
and ratios depend on the powder pump, the diameter of the air tubing, the
powder, and other variables.
1. To set air flows, touch a flow button, then use the slider bar or rotary
dial. Only one setting can be made at a time.
2. When all guns are set up, spray parts, check the applied coating, and
make additional adjustments to the air flows, if necessary.
Refer to your pump manuals for suggested starting points for flow-rate and
atomizing air, then adjust the air flows as required to obtain the best results.
Use Tables 5-1 and 5-2 on the following pages to convert air pressure to air
flow.
NOTE:
The air flow settings in the tables will provide slightly more powder
to the spray guns when applied to a Nordson Modular powder pump and
slightly less powder when applied to a Nordson In-Line powder pump.
