Abstract

An electric-motor-driven housing for a feed pump (1), in particular for a feeding device for fuel, is proposed in which on the commutator side there is a connection cap (5) for the electrical connection contacts (3, 4) and pump inlets and/or outlets (6). The connection cap (5) comprises an electrically conductive plastic, and a connection to a ground potential can be established via an electrically conductive connection. The surface resistance of the connection cap (5) is designed such that a diversion of electrostatic discharge to the ground potential, with attendant shielding from electromagnetic radiation, ensues, and a predeterminable short-circuit current between the electrical connection contacts (3, 4) located directly on the connection cap (5) is not exceeded.
