Laboratory Pumps Intelligent Downsizing for Modern Analytics
The requirements for modern analytical instruments are changing: users in research facilities increasingly rely on low-noise, oil-free vacuum solutions to avoid contamination and, above all, unnecessary noise in laboratory environments.
With the newly developed family of dry-compressing multi-stage Roots vacuum pump Ecodry plus, Leybold has launched a new fore-vacuum pump for the analytics market. The basic idea was to develop a clean, compact and low maintenance pump in the size class 40 to 60 m3/h. The pump class is positioned exactly in the transition area between small laboratory equipment and large machines. The most important innovation, however, is the reduction in noise level that the developers were able to achieve. With an average value of 52 dB (A), it works below the noise limit that is harmful to human health. The sound level of the Ecodry plus is below a conversation at room volume.
The non-contact rotor design is not only designed for a whisper-quiet operation, but also for energy-efficiency and low vibration. In order to be able to produce high-resolution images, such as in electron and scanning tunnel microscopes, the pump must not transmit vibrations. The elementary feature is that the rotors and the housing rotate without friction even at high speeds of up to 12600 min-1. In addition, as measured by industry-standard solutions, it generates less heat, which means lower operating costs for air-conditioning.
In class comparison, the Ecodry plus is also one of the lightest and most compact vacuum components. Users appreciate this feature, as systems for research and development have to deliver their performance in a narrow space. Concerning performance, this pump range was designed to deliver what is needed for the relevant applications.
