Abstract
A reversible, self-priming rotary pump has a housing with a stator of elastomeric material which is softer than the elastomeric material of the rotor on a cam on shaft. The inlet and exhaust ports are separated by a lobe received in a recess in the stator. As the shaft is rotated, the rotor orbits within the stator to pump the fluid between the inlet and exhaust ports, the stator being at least partially compressed along the line of contact with the rotor to form an efficient seal therebetween.
