Beyond Gravity: Centrifugal Separations in CPI Operations

 Follow these recommendations to select the right centrifuge for your application Many chemical process operations require the separation of multiple phases. This can be done in a number of ways, including simple gravity separation, traditional or crossflow membrane filtration and…

Diaphragm Vacuum Pumps in Process Operations

Vacuum is a very widely used utility in the process industries – from pharmaceutical and chemical to food and biotechnology. While some applications require fairly deep vacuum – so-called “fine” vacuum – many other operations rely on vacuum in the…

The Chemical Resistant of VACUUBRAND’s Pumps

For many people, one of the most important features to consider when sourcing a vacuum pump is the ability of that pump to hold up over the long term.  Pumps are exposed to a wide range of operating conditions that…

Cost Savings with Process Vacuum – Part 2

In light of the operational concerns reviewed in Part 1, this chemical recycling firm decided to evaluate different pump technologies.  Fortunately, recent advances in vacuum pump technology make dry-running pumps a viable option for many of those currently using liquid…

Cost Savings with Process Vacuum Systems – Part 1

Summary:  A number of common industrial processes require vacuum, such as distillation or drying operations.  The necessary vacuum has historically been supplied using a variety of technologies that have high operating costs in terms of both consumables (e.g., oil, water)…
