Compact and Economical Pumps and Systems

More compact designs, large-scale integration, an enhanced range of functions, lower noise emissions and an increasing demand for dry-compressing systems are the trends cited by Gebr. Becker. In contrast to oil-lubricated systems, there is said to be no risk of contamination with dry-action pumps, a factor which might be of relevance in the food industry or medical technology, for example. Due to their simpler design, it is claimed that these pumps and systems can even be more economic than the oil-lubricated ones depending on the application and layout. Pumps with contactless operating mechanisms are also said to minimize wear — meaning a considerable increase in service lives.

Pfeiffer Vacuum has developed a powerful turbopump in the shape of the HiPace 60. The pump boasts high levels of economic efficiency and flexibility in all installation positions. With its improved rotor design, the pump is alleged to offer good pumping speed and high gas throughput as well as being immune to particles and dust. The manufacturer claims that the robust bearing system makes the pump ideal for heavy-duty industrial applications.

According to Busch, centralizing the vacuum supply is an economic alternative for customers who operate several vacuum pumps. Indeed, energy consumption is always substantially lower with central vacuum supply. Further advantages flagged up by the company include the higher level of operational reliability and the option of doing maintenance work during operation without the need for downtime. Due to the fact that the central vacuum system is installed outside the production area, it is also pointed out that production staff are no longer exposed to the heat and noise given off by individual vacuum pumps.

To sum up, the supply of high and low pressures is an expensive business. That makes it essential to scrutinize each individual system component in terms of its potential energy efficiency. And this does not just apply when installing new systems: it is also and especially true that a great deal can be saved with older systems in particular.
