Abstract
A fireproof cover for a stator winding of a stator, in particular of electromotive pumps, comprising two or more fire protection caps. The fire protection caps are made of a flame retardant material and can be placed together in an engagement position. The fire protection caps in the engagement position form a knockout opening for carrying through an iron core of the stator and form such a closed fireproof casing for the stator winding, which, however, is air-permeable through a joining gap between the fire protection caps and/or between at least one fire protection cap and the iron core, that as a result of a coil burn of the stator winding, flying sparks and flame propagation to components lying outside the fireproof casing are prevented.
