A flushing apparatus for flushing a downhole pump having a rotor and a stator includes a lifting device forming part of a wellhead assembly. The lifting device is attached to the rotor, such that when activated, the lifting device applies a lifting force to lift the rotor out of the stator. There is a fluid connection on the wellhead assembly for flushing fluid through the stator once the rotor has been removed from the stator.
