Abstract:
1. A pump assembly with a wet-running electric motor comprising a can, which is arranged in a stator housing having first and second axial end-sides, the first axial end-side of the stator housing having an opening that extends into the stator housing and receives the can, wherein a terminal box is arranged on the stator housing on the second axial end-side of the stator housing, the terminal box comprising a tubular housing part, the tubular housing part having a first axial end-side applied onto the second axial end-side of the stator housing, the first axial end-side of the tubular housing part having an opening into which the can engages, a second axial end-side of the tubular housing part opposite the first axial end-side of the tubular housing part is closed by at least one cover element, into which at least one of operating elements and display elements are integrated, and an electrical connection element is arranged on the tubular housing part on an outer periphery thereof, wherein a circuit board with at least one of electrical and electronic components is arranged inside of the tubular housing part, the circuit board extending essentially parallel to the first and second axial end-sides of the tubular housing part and the second axial end-side of the stator housing, the electrical connection element including at least one lead or contact that is electrically connected to at least one contact of the circuit board, and wherein at least the electrical or electronic components facing the stator housing having a construction height extending generally perpendicular to the circuit board and exceeding a predetermined height are distributed in a region of the circuit board that is radially outside of a coaxial periphery of the can such that a free space is created in a central region of the tubular housing part, the can extending beyond the second axial end-side of the stator housing such that an axial end of the can is disposed in the free space in the tubular housing part.
