Abstract

The invention relates to a vacuum pump housing produced especially from grey iron or nodular graphite iron, cast aluminium or special steel casting and comprising a plurality of webs (12, 14) on an outer side of the housing. Said housing is also provided with a covering element extending over at least two webs (12, 14). A cooling channel (16) for guiding a coolant is formed by an inner side (22) of the covering element (18) and two opposing lateral walls (26) of adjacent webs (12, 14).
