Detroit® Rotary Seal Feeders
Especially suited for abrasive and high temperature materials
 All cast iron construction for heavy-duty service. Rotor sealing assembly designed to maintain a tight air seal through spring loaded tension bolts. Rotor assembly has generous sized rotor pockets, which provide increased capacity, allowing the feeder to run at very low speeds, minimizing wear. Removal of end cover plate permits access to rotor and rotor sealing assembly for maintenance without having to remove the feeder from the system.
Access openings are provided on the feeders for internal inspection. Heavy-duty packing glands prevent gas or material leakage at the rotor shaft. High-temperature packing prevents leakage between the rotor sealing assembly and feeder inlet neck. Cooler bearing operation and longer bearing life provided by externally mounted, heavy-duty, self-aligning pillow block bearings. Shear pin assembly located on the driven sprocket of the rotor shaft protects the drive mechanism against feeder jamming from foreign material.
A heavy metal guard with ready access to the drive. The feeder inlet and outlet diameter is maintained to prevent bridging of the material. The inlet and outlet flanges are standard ANSI Class 150 Series. Each feeder is completely factory assembled, tested and shipped as a complete unit ready for installation. Each Rotary Seal Feeder is chain driven by a single reduction, right angle worm gear, totally enclosed, fan cooled motor. The standard current characteristics are 3 phase, 60 hz., 230/460 volt.
Detroit Rotary Seal Feeders are normally installed in a vertical position. However, they may be installed at any angle up to 35 degrees from the vertical, provided they are orientated so that the rotor shaft remains in a horizontal plane. Please advise if the feeder is to be installed other than vertically.
Sizes available from 4" through 14"
