Abstract
A method and apparatus for pumping a steady flow of powder from a powder spray gun of a powder spray system by pumping the powder from a fluidized bed feed hopper to the spray gun via a small auxiliary fluidized bed hopper located in close proximity to the powder spray gun. The apparatus comprises a primary fluidized bed hopper into which reclaimed powder is supplied from a powder spray booth via a powder filter module and a sieve. Powder from the primary feed hopper is pumped to the gun via an auxiliary and much smaller capacity auxiliary fluidized bed hopper located in relative close proximity to the spray gun.
