The Leybold high-vacuum DIJ diffusion pumps are a further addition to the portfolio. Due to their additional ejector stage, these new diffusion pumps achieve a high and stable gas throughput even in the 10-2 to 10-3 mbar range. The innovative heating concept ensures optimized energy transfer as well as optimized thermal insulation for lowest energy consumption. An optimized housing design with connections for both ANSI and ISO components as well as various electrical connection variants facilitates flexible worldwide use of the pumps. Of course, these new diffusion pumps are also available with the already proven "Energy Control Unit", offering energy savings of > 50% compared to unregulated standard pumps, depending on the process cycle. The DIJ line of pumps will become first choice in the all areas of the vacuum industry.
