Diffusion pump (oil diffusion pump) In 1915, German physicist W. Gade published his report on diffusion pump. In 1916, American I. Langmuir made a so-called condensate pump with a cooling system on the pump wall. Using mercury vapor as working medium, these pumps can obtain a vacuum of 10-5 PA. I...
