Choosing the right sealing system for a specific application is not always easy: often there are too many possibilities, and sometimes the gaps in one’s know-how about advantages and disadvantages of different sealing systems are too big. This article will help you to evaluate different sealing systems for agitators and special rotating equipment, including operating limits and arising costs.

The world of rotary lobe blowers on the one side and the world of screw compressors on the other side, both strictly separated from each other: that’s past history now! The compressed air specialists from Aerzener Maschinenfabrik have been successful in building a bridge beetween both worlds.

How to make tablets from potent APIs - Part 2: The overall materials handling concept for potent APIs is the controlling factor in determining the containment performance of the entire installation. There are two basic choices: stainless steel or disposable systems.

Increased investments in Eastern Europe will provide growth opportunities for compressor manufacturers.

Bulkflow Technologies is a world leader in the indirect heating and cooling of powder and bulk solids in many industries worldwide (chemicals, polymers, fertilizers, detergents, minerals, oilseeds, grains, food products, sugar and biosolids). In the last few years, Bulkflow has introduced this technology to the sugar industry, where it has been established as a proven and effective method of cooling sugar crystals before storage and packaging.

This year decanter specialist Flottweg celebrates its 75th anniversary. The decanters are used for continuous separation of suspended solids from liquids, clarification of liquids, and classification of fine particles. But, it all began with a motor...

Finned pack heat exchangers — coils — find wide application in air handling units (AHU) and ventilation systems. Engineers often approach the rating of finned pack heat exchangers from one side only, whether that is the fluid side or the air side. As a result, a number of myths and suppositions endure in the industry, leading to errors and misunderstandings. This article deals with water heating and cooling coils, and focuses on the properties of the water or brine (glycol).

The Gravejo (Poland) plant of particle board manufacturer Pfleiderer was too frequently replacing high-pressure pumps on its production lines. The pumps play an essential part in the main continuous production process, delivering resinous glue to nozzles where it is sprayed on to the wood fibers.

Material flow problems in coal fired power plants are not so uncommon: Coal gets stuck in bunkers, hoppers and hold or forms material bridges within the conveying system. But there is something that can be done about it: Modern vibrator systems can help to get bulk materials flowing freely again...

Hoses in the plastics industry tend to be rather inconspicuous and their importance easily underestimated. However, observant visitors to a plastics processing factory are often surprised at the hugely diverse applications in which hoses are used.
