Title: (DE) AXIALE FLUSSPUMPE MIT SPIRALFÖRMIGEM FLÜGELRAD
(EN) AN AXIAL FLOW PUMP WITH A SPIRAL-SHAPED VANE
(FR) POMPE AXIALE A PALE EN FORME DE SPIRALE
Abstract: front page image
(EN) An axial flow pump (10) is presented which includes a housing (1) with an inlet (2) and outlet (3) and a magnetically active rotor (5) in the housing which is provided with a passage (6) in the interior and with at least one spiral-shaped vane (7) in the passage, wherein the pitch of the vane (7) varies in the axial direction. The axial flow pump (10) furthermore includes an electromagnetic drive (4, 8) with a stator (8) which is arranged at the housing and cooperates with a magnetically active rotor.
(FR) L'invention concerne une pompe axiale (10) comprenant un corps (1) pourvu d'un orifice d'admission (2) et d'un orifice d'évacuation (3), et un rotor à action magnétique (5) ménagé dans le corps à l'intérieur duquel est formé un passage (6) dans lequel est placé une pale en forme de spirale (7). Le pas de la pale (7) varie dans le sens axial. La pompe axiale (10) comprend également un moteur électromagnétique (4, 8) pourvu d'un stator (8) qui est agencé au niveau du corps et coopère avec un rotor à action magnétique.
