Abstract (en)

[origin: EP0801229A2] An outer part (8) of the running wheel (3) extends out of the pump housing (2). With rotation of the running wheel materials picked up by the worm shape of the outer running wheel are drawn into the running wheel aperture of the pump housing as pump input and are impelled. A somewhat tangential pump outlet (10) is provided in the torus-shaped pump housing and a drivable pump shaft (4) is connected coaxially with the outer running wheel part. A striker strip edge (17,18) or the worm periphery edge (9) have cavities (25) or raised formations (26) as obstructions for the disintegration of the solid material moved past the outer running wheel part.
