Abstract

The invention proposes an electric pump (1) for delivering a fluid. The electric pump (1) has a first pump component (3) with a first interface (7) and has a second pump component (5). The first pump component (3) and the second pump component (5) are in contact with one another at the first interface (7). Here, the first interface (7) has an incline (11) with respect to a plane running perpendicular to a longitudinal axis (13) of the electric pump (1).
