An oil pump configuration for a motor vehicle includes an oil pump having a pump part and an electric pump motor, wherein the pump part is operatively connected to the electric pump motor. The pump part and/or the electric pump motor can be mounted to a housing which at least partially delimits an oil chamber. Sealing problems at the pump part are prevented and the required installation space is low because the pump part can be mounted inside the housing and the electric pump motor can be mounted from the outside to the housing.
