The new pumps are characterised by their compact design and quiet, low-vibration operation (<47 dB[A], and <42 dB[A] in stand-by mode), states the company. It offers excellent water vapour tolerance thanks to the two stage gas ballast. As a result condensation in the vacuum pump is avoided. With these features, the pumps are ideal for use in many applications in analytics, biomedicine, pharmaceuticals and research and development, adds the firm. They are used in mass spectrometry, electron microscopy, surface analysis, accelerators and laboratory applications, but also in the semiconductor industry, coating processes and gas recovery.

The new pumps’ active temperature control ensures optimal cooling and guarantees the lowest noise level. The firm states that it is proud of the fact that its new scroll pumps have the lowest noise emissions in its class. These dry pumps can also be easily connected to other Pfeiffer Vacuum products, such as turbopumps, or operated by higher-level controls via the RS-485 or ProfiNet interface. The company drives sustainable solutions and helps to reduce the environmental impact and carbon footprint with its new engine concept.

Specialist Book „Heat Transfer Technique“The comprehensive standard work „Heat Transfer Technique“ offers not only a detailed and well-founded presentation of the basics of heat transfer technique, but also shows the latest state of the art and the latest regulations in the use of organic fluids. Thematically, the book is rounded off with an overview of property data of organic heat transfer fluids as well as many use cases from practical experience.

An intelligent interface makes it possible to define specific pressure ranges or a rotation speed setting mode, so that the pump can be optimally adapted to suit the application. This minimises wear in the pump resulting in longer to service time intervals. The proven quality of the company’s products with first-class, durable components also ensures a long service life as well as lower operating costs, mentions the firm. The pumps are easy to maintain, which not only reduces the time to service but also ensures the highest level of reliability. The integrated safety valve and the self-regulating operation of the pump guarantee safe and reliable use, claims the company.

The powerful motor is up to 15 % more efficient than conventional drives. This ensures outstanding performance while keeping temperatures low, which in turn simplifies the cooling of systems and plants, concludes the firm.
