A metering pump assembly includes a metering space () and a displacement body () which is linearly movable via a conrod (). A helical spring () designed as a compression spring () impinges the conrod () with a force in a movement direction. The helical spring () at at least one axial end () is designed such that in a relaxed condition an end () of a spring wire projects axially with respect to a connecting winding ().
