Abstract: A pump for particulate material includes a pump chamber wherein material flows into the pump chamber under negative pressure and flows out of the pump chamber under positive pressure. A plurality of pinch valves are provided to control flow of material into and out of the pump chamber. The pinch valves are operated independent of each other and of the pump cycle rate. A modular design of the pump is provided. A pump control feature is provided for air flow rate control during positive and negative pressure conditions.

Abstract: A dense phase pump for particulate material includes a pump chamber wherein material flows into the pump chamber under negative pressure and flows out of the pump chamber under positive pressure. A plurality of pinch valves are provided to control flow of material into and out of the pump chamber. The pinch valves are operated independent of each other and of the pump cycle rate. A modular design of the pump is provided.

Abstract: An apparatus for emptying powder from a container, such as an original shipping box includes a support having a vibrating unit for loosening the powder within the container. A powder pick-up tube and an attached powder pump draw powder from the container and transfer the powder to a powder spray gun. The lower end of the pick-up tube includes a positively pressurized fluidization unit for locally fluidizing the powder at the pick-up tube inlet. The pressurized fluidization unit primarily assists in providing a consistent draw of powder up the pick-up tube.
