A color changer has a common feed passage that is connected to two or more inlet passages. The common feed passage can be reverse purged in a direction that is opposite a direction of powder flow through the common feed passage. A valve element seals a supply port that connects the inlet passage to the common feed passage to eliminate dead space and form a near bore line seal. The valve element is an elastic material that expands in response to applied compressed air inside the valve element.

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.
