Abstract
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 of the face of the upper ring intended to come into contact with the wall of the structure. The invention also consists in a fixing system comprising an annular flange disposed coaxially with the pump body around the inlet orifice of the pump. At least one second cavity in the face of the end of the pump body in contact with a face of the upper ring is coupled with the first cavity to form a housing, and at least one flexible material stud inserted into the housing.
