Abstract

The rotor bearings (40-42) are mounted in the high pressure end of the pump casing, this end also containing a bearing chamber (37) separated from the work region of the pump by a partition wall (5) containing an opening (8) surrounding the cylindrical rotor stop (9). A sealing ring is housed in a ring-shaped cavity (10) in the partition wall and protrudes outwards from this cavity to surround the rotor stop. The ring is not rotatable relative to the casing and has an axial sealing surface in contact with the casing, and a radial sealing surface in contact with the rotor stop. A channel extending through the ring in a radial direction and having an open end facing the rotor stop is linked with a pressurised lubricant source.
