Abstract

A single-stage liquid-ring vacuum pump having a double axial inlet with flat-distribution plates comprises a central body (2), an impeller (5) eccentrically housed in a chamber (4) delimited by the central body (2), a flanged suction manifold (15) in fluid communication with two suction openings (8) located at opposite ends of the central body (2), a flanged exhaust manifold (17) in fluid communication with two exhaust openings (9) located at opposite ends of the central body (2). The flanged suction manifold (15), flanged exhaust manifold (17) and feed manifold are integrated into the central body (2), so as to reduce weights and bulkiness as compared with the pumps of the known art, the pump performance being the same.
