The invention relates to a pump (1) with an integrated electronically commutated direct current motor (2) with permanent-magnet arranged in a wet space inner rotor, which forms a compact Pumpenrotorbaueinheit (3) with a centrifugal pump impeller (22) disposed one in a drying space (4), claw pole ( 6) of soft magnetic material, an annular winding (12) and one (on the claw pole 6) mounted and (around the coil 12) disposed about said soft magnetic return ring (13) comprising, claw-pole stator (9) and (a gap pot 10) of the drying room from the wet space (5) separates. Object of the present invention is to show a pump with higher efficiency and performance can be achieved than with conventional claw pole stators while but whose benefits can essentially be maintained, in particular light weight, simple construction and economic manufacturability and robustness. This object is achieved by the characterizing part of claim 1.
