Abstract
An improved powder pump for pumping air entrained solid particulate powder material comprising a pneumatic conveyor line within which there is located a low pressure venturi pumping chamber. This venturi pumping chamber is intersected by a powder supply passage through which powder is drawn via a siphon tube into the conveyor line from a fluidized bed source of powder material. Over the inlet end of the siphon tube there is a cone shaped deflector plate which functions to reduce the inflow of air bubble created powder voids and consequent uneven flow of powder from the pump.
