Abstract (en)
[origin: WO2019221610A1] A centrifugal pump in which a centrally placed impeller/shaft system is eliminated and replaced by one or more active propellers placed tangentially in the fluid-filled pump casing. The axial force from the propeller system sets the fluid into rotation, both directly in the propeller jet and by viscous forces in the rest of the pump casing, so that tangential and radial velocity arises through the pump and thereby pressure and capacity. A method for using the centrifugal pump and a unit to be connected to the centrifugal pump are described as well.
