Global vacuum technology supplier Pfeiffer Vacuum introduced its new turbo pumps and diaphragm pumps at the Analytica trade show in Munich, Germany from May 10 to 13.

With a pumping speed of 32 ℓ/s Pfeiffer Vacuum notes that the HiPace 30 is currently the most powerful turbo pump of this size on the market. Owing to the small footprint and low vibration level, the pump is particularly suited for integrating in compact analysis systems such as portable mass spectrometers, small electron microscopes, and leak
detectors. At 2 kg total weight, the HiPace 30 is ideal for portable applications.

As a result of the sophisticated rotor design of the HiPace 30, high gas throughput and extremely good compression of light gases are achieved. This ensures a low residual gas background, which is ideal for mass spectrometry applications.

Moreover, the HiPace 300 H is the most powerful compression turbo pump currently available in the pumping speed class of 300 ℓ/s.

With a compression ratio of 107 for hydrogen, it is suitable for generating high and ultra-high vacuum. Owing to the high compression ratio, a low residual gas spectrum is created in the chamber, which is desirable for mass spectrometry applications, for example.

The HiPace 300 H has a very high critical backing pressure of 30 hPa as a result of its advanced rotor designs. This allows the pump to reach ultra-high vacuum, even when operating with high backing pressures, as occurs in combination with diaphragm pumps. Owing to the integrated “intermittent operation” function, the HiPace
300 H switches on a connecting backing pump only if the backing pressure is no longer adequate. This reduces the energy consumption of the entire vacuum system by up to 90%.

The HiPace 30 and HiPace 300 H have a so-called hybrid bearing. This combination of a ceramic ball bearing on the fore-vacuum side and a permanent-magnet radial bearing on the high vacuum side creates a particularly robust bearing concept. This in turn leads to very high reliability and a long service life.

Diaphragm Pumps for HiPace Turbo Pumps

Pfeiffer Vacuum notes that since the HiPace turbo pumps are equipped with a 24 V direct current power supply, the diaphragm pumps of the multi volt platform (MVP) direct current series are the ideal backing pumps.

The brushless direct current motor allows adjustments of the speed to the specific needs of a particular application. In the automatic boost mode, the pump runs at full speed and reduces once a certain vacuum is reached. In this way, high performance, long maintenance intervals, and low noise and vibration levels are achieved.

The installation of the system is simple and inexpensive as a result of the unified communications via a D-sub connector. Owing to its light weight and compactness, MVP direct current series pumps are ideal for integration in increasingly small analytical systems and turbo pumping stations as well as mobile applications.

The two-stage pumps are equipped with a magnetic gas ballast valve, so that improved process reliability and service life are achieved. The operating temperature ranges from 5° C to 40° C, and therefore covers a wide range of applications. The easy maintenance of the pumps and the long service intervals, of about two years, guarantee very low operating costs.

Another important advantage of diaphragm pumps is their long service life. At sensitive locations, diaphragm pumps do their work not only reliably, but also at a low vibration and noise level. The noise level is well below that of rotary vane pumps.

In addition to individual components, Pfeiffer Vacuum offers compact, high-vacuum pumping stations.

“In an increasingly changing competitive environment, Pfeiffer Vacuum is regarded as an ideally placed and very sound company,” says Pfeiffer Vacuum CEO Manfred Bender.

He concludes that the company is proud that its product developments used in laboratory technology, analytics and biotechnology have been setting new standards across the entire vacuum industry for years.
