Abstract

The invention comprises a pumping arrangement (1) consisting of a housing or casing (2) with a cavity (2C) whose inner surface (2a) has a circular cross section, one vane or a plurality of vanes (3) arranged inside the casing's cavity to pump by means of a rotary movement a liquid from an inlet (22) in the casing to an outlet (21) in the casing, said inlet and said outlet being separated from one another, and at least one end panel section (7) for the casing. A centre of rotation (4') for said vane (3) is eccentric in relation to an assigned centre (2') of said inner surface (2a), and said vane (3) is capable of reciprocal movement in relation to a shaft (4) at said centre of rotation.
