Abstract
Separating apparatus comprises a rotor having a plurality of impeller blades rotatably mounted in a support housing. In the normal course of apparatus use, fluid flow occurs through opposed rotor open ends. Drive motor elements for rotating the rotor are mounted partly in the rotor and partly in the surrounding casing whereby the rotor may be driven without the necessity of a drive shaft attached to the rotor, and the opposed rotor ends remain unobstructed. In one rotor embodiment, fluid enters the opposed rotor ends and is discharged radially by the rotor blades. In a second embodiment the fluid enters one rotor end and is discharged along an axial path from the opposite end.
