The basic sealing task in mixing applications is to seal the rotating shaft as it passes through the vessel wall. Depending on the operating conditions — pressure, temperature, agitator speed, etc. — different types of seals are used. As this article shows, mechanical seals offer many advantages over other types of seals. Particularly if hazardous or explosive substances are being mixed, a mechanical seal is mandatory.

On a major part of the pump breakdowns in the Chemical Process Industry, the causes are NPSH problems, gas admixtures in the transported fluids, dry running or operating a pump outside the permitted range.

Since the company was founded in 1959, the clear objective of Vega Grieshaber has been the development of innovative and pioneering products for challenging measurements of level, point level and pressure. Particularly in the area of radar sensor technology for level measurements, almost the entire process engineering world looks to the company from the Black Forest for solutions.

Ideas in technical gases don’t have to remain pipe dreams. When Carl von Linde invented his air separation process over a century ago, it marked the start of a success story that continues to this day. Technical gases revolutionized entire sectors, and continue to do so today. Just like Linde — the market leader in the gas industry who sets standards for these raw materials supplied in pressure cylinders …

Oil as a natural resource is becoming scarcer and more expensive and there is a need to look at eco-friendly ways of extracting it, thereby reducing CO2 emissions. White biotechnology offers a solution: scientists are now using microorganisms such as bacteria to generate substances for the production of polymers. The advantage is that these miniature biochemical factories run on renewable resources or agricultural waste converting it into valuable chemicals.

Regardless of whether for distillation, filtration, drying or clarification — without separation technology, nothing goes. After all, most raw ingredients and products of chemical reactions are mixtures of substances that need to be separated for further processing. So it is good to have a partner who is a single provider capable of supplying everything from mechanical separation systems to exhaust air purification.

What do tile adhesive, medication in the form of tablets and yogurt have in common? With all of these products, a specific formula needs to be followed to the letter to make sure the required quality can be guaranteed. To do this, the individual raw ingredients not only need to be safely stored, conveyed and processed. Ultimately, they also need to be added with precision to the production process. This is sometimes a tricky challenge — and one that AZO has been living up to for nearly 70 years. Starting with the development of a cyclone screening machine, the creative engineers from Osterburken/Germany are responsible for numerous innovations in the field of bulk materials handling. Today, the AZO Group automates raw materials handling in the food, pharmaceuticals and chemicals sectors all around the world.

A matter of ideas or: How grinding becomes as easy as 1, 2, 3 — Sometimes, situations require us to reinvent the wheel. Taking another perspective, gaining new insights from an external user’s perspective, or getting to the bottom of an issue, can help us to find an original solution with an existing product.

A new isolator for sterile filling combines cleaning, sterilizing, filling & closing, monitoring and precision-counting magazining functions in one.

Shortly after acquiring new companies in America, industrial gases specialist Messer is investing in the construction of a new CO2 plant in Keyes, California. The plant produces 450 tonnes of carbon dioxide per day and supplies companies in Northern California and the surrounding areas.
