Abstract
In accordance with the invention, the vacuum pump cooling system includes tubes expanded along their entire length in bores through the vacuum pump body. The tubes can be made of stainless steel, and inserted into a vacuum pump body made of cast iron. This prevents the risk of corrosion of the vacuum pump body by a cooling liquid passing through the tubes to cool the vacuum pump body.
