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: A diagnostic apparatus for a powder coating material pump includes a detector that uses pressure or flow to detect a fault in the pump, the diagnostic apparatus being external the pump, internal the pump or a combination of external and internal the pump. Another diagnostic device is provided for a powder coating material pump, and includes a light source in close proximity to the pump, the light source having an on condition and an off condition wherein one or both of the on condition and off condition provides information about the pump performance. An exemplary pump is a dense phase powder coating material pump.
