See full text

The invention relates to an eccentric screw pump (100), in particular for conveying viscous, highly viscous and abrasive media, having a longitudinal direction L, having a conical, helically wound, at least single-start rotor (1) having a gradient h, having at least one eccentricity (e1, e2, e3, . . . en) and at least one cross-section d that is rotatably arranged in a single or multi-start conical stator (2) wherein a plurality of chambers (3, 4, 5 . . . n) each having a volume (V3, V4, V5 . . . Vn) is formed between the rotor (1) and stator (2) that serve to convey the medium and wherein the chambers (3, 4, 5 . . . n) between the stator and the rotor are limited by a sealing line D. The volumes (V3, V4, V5 . . . Vn) of each individual chamber (3, 4, 5 . . . n) between the stator (2) and the rotor (1) are equal.
