The document describes the Fuller-Kinyon Type M pump, a heavy-duty screw-type pneumatic pump used to convey dry and pulverized materials over long distances. The pump is constructed of cast iron and steel, with a cast iron base and ball bearings supporting the dynamically balanced screw. Standard equipment includes a pressurized seal and bearing assembly to extend component life. The pump conveys materials by advancing them through the screw barrel using compressed air to fluidize and transport the material through the discharge line. Common applications include transferring materials between silos and loading/unloading railcars and ships.
