A seat assembly is provided with a pump for a fluid system, such as an air system. The pump has a housing with a wall surrounding a recess, with the housing defining an inlet passage and an outlet passage. A diaphragm is positioned through the wall with a distal end within the recess, and with the inlet and outlet passages in fluid communication with an opening to the pumping chamber of the diaphragm. A cam is supported for movement along a path about a central axis within the recess, and is connected to the distal end region of the diaphragm. The cam alternately moves the distal end region radially outwardly from the central axis to compress the pumping chamber and provide flow to the outlet passage, and moves the distal end region radially inwardly towards the central axis to expand the pumping chamber and provide flow into the pumping chamber.
