ABSTRACT:
A rotary disc pump comprises an outer housing with an inner cylindrical rotor chamber having an inlet at one end and an outlet at its outer periphery. A rotor assembly in the chamber comprises at least two parallel spaced discs disposed co-axially in the chamber and connected together for rotation about their center axis. The inner opposing faces of the discs are spaced a predetermined distance apart, and a series of raised ribs or vanes are provided on at least one of the opposing faces, with the vane height being less than the disc spacing to leave a clearance between the opposing disc surfaces.
