 Selecting a Turbo Pump for Your Application
Trying to select the best turbo pump for your application can be a difficult and sometimes frustrating exercise. The questions range from pumping speed to bearing type and mistakes here can cost not only money but also the performance you need. This is a very basic guide to selecting a turbo pump but for more information it is wise to discuss your application with the pump manufacturer.

 Part 2 of a 5 Part Series –
The Integrated Web-shop
Each month Edwards will explore the new features of our website, and how to use the new functionality to its optimal ability
A significant improvement to the Edwards website was the integration of online shopping on the same page as the product information. In the past customers who wanted to place an order had to navigate to a separate website and find the product all over again. On the new edwardsvacuum.com ordering products is integrated into one site. In this edition we will show you how easy it is to place an order online.

 New Biofuels Brochure
Biofuels are oleochemicals – chemicals derived from agricultural oils and fats – and include hydrogen, methanol, ethanol and biodiesel (methyl ester). The oleochemical industry, like the petrochemical industry, uses vacuum applications such as deodorization, distillation, evaporation and reactor systems. Edwards has an extensive range of process vacuum technologies. We can provide you with all of the required vacuum equipment needed in biofuel processes - from biodiesel and bioethanol production to glycerin and fatty acid purification. |

Fernand Holweck – A Hero of Vacuum
The legendary French scientist Fernand Holweck was born in 1890 and made significant impact on a breathtaking range of activities which are still highly relevant today. He studied at the Ecole de Physique et Chimie and graduated in 1910 having been amongst such luminaries as Pierre Curie and Paul Langevin. |

A metallurgical customer has a throughput requirement of 10 mbar l/s to 300 mbar l/s in a pressure range of 1x10-3 mbar to 0.1 mbar. The pump must be extremely reliable offering very high pumping speed and throughput, high cross-over pressure and must be industry proven. What pump does this customer want / need?
Hint, the pump is a “secondary” vacuum pump (or high vacuum pump) and can be found in section 9 of the Edwards 2007 product catalog. Once you determine what pump the customer wants / needs, size the mechanical pump required to “back” the chosen secondary pump.
Bonus question: How many EH4200 roots blowers does it take to match the throughput of the secondary pump required for this application?
