Abstract

A product pump assembly including a product pump having a product receiving inlet, a product discharge outlet, a product chamber, and an air port. A cone-shaped feed valve in the product chamber is forced upwards against the inlet thereby sealing it when pressurized air is forced through the port into the chamber, during the evacuation cycle of the pump assembly. The pressurized air is deflected against the valve sweeping the product out of the chamber through the outlet and via a delivery line to the product collector. An ejector is energized during the fill cycle to withdraw the air from the chamber through the air port, thereby opening the valve and pulling the product into the chamber.
