Abstract (en)
[origin: EP1584820A1] Screw centrifuge wheel pump (1) comprises a guide blade (5) arranged in the region of an inlet opening (3c) and protruding into the inner chamber of the running wheel (2). The guide blade has an edge (5a) which protrudes into the inner chamber of the running wheel in the rotary direction (4a) increasing in the direction of the axis of rotation. The running wheel and the guide blade are structured so that a part of the solid mixture flows along an inlet blade edge (2a). An independent claim is also included for a process for conveying a liquid with solid additives. Preferred Features: The guide blade slides in the direction of the axis of rotation.
