The present invention relates to the field of high rotation speed vacuum pumps, which are fastened to and connected to a structure such as a vacuum enclosure or a pipe to generate a hard vacuum. It consists in an annular fixing flange including holes cooperating with headed bolts to fasten a vacuum pump to a structure. The flange comprises an upper ring and a lower ring cooperating to clamp the end of the pump body between the upper ring and the lower ring, and at least one first cavity in a face of the upper ring that is in a plane perpendicular to that...


The invention claimed is: 1. A system of rings for fixing a vacuum pump to a wall of a structure the body of the pump having an end capable of being clamped by the system of rings, said system of rings including bolt holes adapted to cooperate with headed bolts for fastening the vacuum pump to the structure with the system of rings pressed against the wall, characterized in that the system of rings comprises: a lower ring and an upper ring cooperating to clamp the end of the pump body between the upper ring and the lower ring, the upper ring including a...
