Abstract
The peripheral pump includes a wall bounding a pump chamber and provided with a substantially annular delivery port with a base having a circular segment with a center; a circular cylindrical impeller revolving in the pump chamber, having two end faces and a rim of blades disposed at intervals along a circumference of the impeller so that a groove-like gap is formed between two adjacent blades, the groove-like gap having a base, as seen in a longitudinal section through the pump, having a circular segment with a center substantially coincident with the center of the circular segment of the delivery port, the center of the circular segments being located within an outer contour of the impeller.
