Title: (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.
