Contvac Diffusion pumps
Diffusion-pump listings for high-vacuum installations with the required supporting equipment.
High vacuum with backing, fluid and cooling
A diffusion pump is one part of a high-vacuum system. Select its inlet size and gas throughput together with the backing pump, operating fluid, cooling and controls. Trapping and pipework affect contamination and chamber performance. Check the selected model’s installation data before choosing a replacement by size alone.
What to check when selecting this range
Specify the process, target pressure and gas load. Confirm the backing pump, operating fluid, cooling and any trapping requirements.
Compare the listed models
Compare values with their stated gas, frequency and configuration conditions. A blank specification means it needs confirmation. Listed equipment is subject to a quotation; inclusion here does not indicate stock.
