The venturi lift pump takes the powder out of the fluidized feed hopper
or powder box, atomizes it and delivers it to the gun tip in a
controlled and even pattern. A good venturi pump has a minimum of
parts, is easy to remove from the hopper and is lined inside with
inexpensive replaceable plastic inserts. These inserts need to be examined
frequently and replaced when the hole-size enlarges and forces
higher flow rates in order to maintain the desired powder output.
