Venturi Lift Pumps that comes with the King Coat Hopper

[Guest]

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.

Why would you need plastic inserts? just to change the orifice size or???

I think because over time the powder can wear parts out.

Yes, powder does wear out Venturi Pumps and the higher the powder flow the faster the wear. Also, the more texture powder you use the faster they will wear too.
