A pump includes an electric motor with a rotor mounted rotatably about an axis of rotation and circumferentially surrounding a stator that includes a stator core and coils wound on the stator core. The windings are defined by a winding wire with winding wire end sections electrically contacted directly with a printed circuit board at an end surface through insulation displacement contacts each including at least one opening for insertion of a winding wire end section, the at least one opening being a slot extending parallel or substantially parallel to a surface of the printed circuit board.
