Abstract
A rotary pump is provided for fluid transfer. The pump includes a planar housing, an elongated rotor, a pair of double-concave blades, fore and aft cover plates, and a gear box. The housing has a circular center cavity, and a pair of circular lateral cavities overlapping the center cavity and disposed along a longitudinal axis. The rotor is disposed on a rotor shaft along a rotation axis perpendicular to the longitudinal axis within the center cavity. The blades flank the rotor and are disposed within their corresponding lateral cavity and turn on corresponding blade shafts parallel to the rotor shaft. The fore and aft cover plates flank the housing along the rotation axis to cover the center and lateral cavities. The blades turn opposite from the rotor.
