Abstract
A bladeless pump for fluids, such as gases that may contain particulate matter, drivable by a motor, consisting of an assembly of rotors or discs stacked against each other. Each rotor/disc has a runner portion on an outer area separated from its center, and a central portion having two or more spokes, divided by openings. The spokes are typically thicker than the rest of the discs. When many discs are placed together and spun on a motor-driven axle, air may be drawn in adjacent the rotor assembly, to the inter-disc openings, and compressed as it enters the area A spiral-shape volute is provided adjacent the outer πM of the disc assembly, receiving pressurized air and releasing it from a motor housing. Applicant's bladeless pump may include a base for receiving the rotor housing and the motor, which may include a housing to substantially enclose the motor and its housing.
