Pfeiffer Vacuum has received yet another major order for leak detectors from CERN. CERN is seated in Geneva on the Franco-Swiss border and is the largest center for particle physics research in the world. Its main business is fundamental physics - finding out what the universe is made of and researching the basic constituents of matter. The particle accelerator LHC (Large Hadron Collider) has a circumference of some 27 kilometers and collides proton or ion beams at nearly the speed of light. The LHC is the largest vacuum installation on Earth with thousands of welds, flanges, feedthroughs and complex internal circuits.

For the accelerated particles to travel in beam lines, ultra-high vacuum (UHV) is essential. To maintain such a very low pressure it is crucial to keep the leak rates as low as possible. The most advanced leak detector technology from Pfeiffer Vacuum has been chosen by CERN. Andreas Schopphoff, Head of R&D Market Segment: "The cooperation between CERN and Pfeiffer Vacuum is based on many years of working together in a spirit of trust. We are very proud that our advanced leak detection technology has been chosen once again for its future projects."

The leak detector ASM 340 is an easy to operate device that can detect leaks down under 5 x 10-13 Pa m3/s. With a built in backing pump of 15 m3/h small as well as big volumes can be leak tested. The patent pending functionality makes it possible to start at 100 hPa which can be very convenient for such a big installation like the LHC. Furthermore, the leak detector is so compact that it can be easily maneuvered underneath the cryostats and beam lines of the LHC.

Nowadays helium leak detectors are based on a patented design from Dr. Becker at Pfeiffer Vacuum who proposed to use a turbopump as a kind of filter and safety element in front of a mass spectrometer. At the time, CERN was one of the first customers to buy this innovative technology and has continued to be a major user of Pfeiffer Vacuum products to this day. Generating the vacuum inside the LHC, measuring it and analyzing the partial pressure requires comprehensive vacuum technology, a major part of which is being supplied by Pfeiffer Vacuum.

CERN was founded in 1954 and now employs around 2500 staff and hosts more than 10,000 visiting scientists from all over the world.

new HiLobe® Roots vacuum pump series set new standards


Hannover, April 1st, 2019 - Pfeiffer Vacuum introduces new high-performance vacuum pumps:

Roots pumps of the HiLobe® series set new standards

- Short pump-down times - ideal for load-lock chambers or leak detection systems

- Powerful and energy-efficient series - compact design, intelligent interface technology



ComVac 2019.
Pfeiffer Vacuum, one of the world's leading provider of vacuum technology, will be presenting new vacuum solutions at the ComVac, which will take place at the Hannover Messe trade fair from April 1-5, 2019. The special highlight at booth D 16 in hall 26 are the new Roots pumps of the HiLobe series. For the first time, Pfeiffer Vacuum experts will present these innovative vacuum pumps - in addition to their extensive product portfolio - which can be used for numerous industrial vacuum applications such as electron beam welding, vacuum furnaces or freeze drying. The pumps of the HiLobe series are of particular interest for fast evacuations (load-lock chambers or leak detection systems). Furthermore, they are suitable for use in coating applications.

Compact and powerful Roots pumps
The compact Roots pumps offer a wide nominal pumping speed range of 520 - 2.100 m³/h. This is made possible through the new drive concept in conjunction with frequency converters. Thanks to their individual speed control, the pumps can be precisely tailored to customer-specific requirements. Thanks to this powerful drive concept, the HiLobe achieves approximately 20 percent shorter pump-down times than conventional Roots pumps. Rapid evacuation reduces costs and increases the efficiency of the production system.

Process-reliable and cost-efficient vacuum
The maintenance and energy costs of the HiLobe are >50 percent lower compared to conventional Roots pumps. The reason for this is a drive with energy efficiency class IE4 and the special rotor geometries of the pumps. The sealing concept also contributes to this. The pumps are hermetically sealed to the atmosphere and have a maximum integral leakage rate of 1 · 10-6 Pa m³/s. Dynamic seals are eliminated and, as a result, maintenance is only required every four years. Due to the innovative sealing concept in the suction chamber, the use of sealing gas is superfluous in most applications, which also has a positive effect on the operating costs. Since the operation of the HiLobe Roots pumps is possible even at ambient temperatures of up to +40°C with flexible air cooling, cost-intensive water cooling is unnecessary.

Control and communication are the essential factors for increasing system availability. The intelligent interface technology of the HiLobe allows very good adaptation and monitoring of the processes. This facilitates anticipatory and efficient work. By integrating such condition monitoring, information about the condition of the vacuum system is always available. In addition, condition monitoring increases system availability allowing users to plan maintenance and repair measures in a useful and anticipatory way and prevent cost-intensive production downtimes. These advantages lead to a long service life and maximum operational safety. Depending on their suitability for the existing system, the HiLobe vacuum pumps can either be aligned vertically or horizontally. This allows maximum pumping speed and a more customized and efficient use of space at the customer's production site.

"With the HiLobe Roots pumps our customers are able to reduce energy and operating costs and consequently make production more cost-efficient. For a sustainable reduction of energy consumption and operating costs, it is not enough to solely base it on the energy requirements of a vacuum pump. The type of cooling, the maintenance intervals and the control also have a decisive influence on the overall energy balance. We are proud to be able to offer our customers this holistic approach," says Dr. Ulrich von Hülsen, CTO of Pfeiffer Vacuum Technology AG.
