Title (EN) CENTRIFUGAL PUMP
(FR) POMPE CENTRIFUGE
(DE) KREISELPUMPE
Abstract:
(EN) The centrifugal pump (1) comprises a plurality of pump stages which are axially arranged between a top part (4) and a base part (2). The pump stages are peripherally surrounded by an outer casing (3), and axial end of the outer casing (3) being fastened to the top part, and the other axial end to the base part ,and the outer casing (3) forming the mechanical connection between the top part (4) and the base part (2).
(FR) L'invention concerne une pompe centrifuge (1) comprenant plusieurs étages de pompe, lesquels sont disposés axialement entre une partie supérieure (4) et une partie inférieure (2). Les étages de pompe sont entourés sur leur périphérie par une enveloppe extérieure (3), une extrémité axiale de l'enveloppe extérieure (3) étant fixée à la partie supérieure, l'autre extrémité axiale étant fixée à la partie inférieure, et la liaison mécanique entre la partie supérieure (4) et la partie inférieure (2) étant formée par l'enveloppe extérieure (3).
(DE) Die Kreiselpumpe (1) weist mehrere Pumpenstufen auf, welche axial zwischen einem Kopfteil (4) und einem Fußteil (2) angeordnet sind. Die Pumpenstufen werden umfänglich von einem Außenmantel (3) umgeben, wobei ein axiales Ende des Außenmantels (3) am Kopfteil, das andere axiale Ende am Fußteil befestigt ist und die mechanische Verbindung zwischen Kopfteil (4) und Fußteil (2) durch den Außenmantel (3) gebildet ist.
