The new vacuum system from Edwards offers oil-free degassing for specialty steels that offers savings in energy costs. Features of the dry pumping system and the history of the company are presented.

In order to create a vacuum within a closed container, or vessel, we need to remove the molecules of air and other gases that reside inside by means of a [...]

Evacuating a rotational mold before you make a part may sound like a strange idea, but it's also a simple way to achieve faster cure times and improved part properties. [...]

New equipment for the recovery of refrigerant from air-conditioning equipment includes a recovery unit combined with a vacuum pump. The units also have a self-purging system, which solves the problem of cleaning the unit when the refrigerant is changed. Compressors that require no oil eliminate the need for filters. Katy Instruments, based in Toledo, OH, produces a recovery system with an oil-free compressor and a vacuum pump., * In the language of refrigeration service techniques, 'recovery' and 'evacuate' are two terms that are often used interchangeably. In fact, they have special and distinct meanings. Evacuate has traditionally [...]

David Middlehurst of Siemens looks at liquid-ring vacuum pumps and how best they are used on different sections of papermaking machines Liquid-ring vacuum pumps have for many years been indispensable [...]

Stauch GmgH, a Hilden, Germany composite material supplier, has developed a compression molding press powered by a vacuum pump. It is said to consume less than 20% of the energy used by hydraulic compression presses, plus it costs 50% less. The new machine can handle most common materials currently compression molded, including polyurethane foams, thermoset polyesters and reinforced thermoplastics. The company has applied for patents and hopes to market the new presses in North America, Japan and Europe.

VACUUM GENERATORS VS. VACUUM PUMPS Vacuum generators are compact sources of instantly applied vacuum, but the devices are not inexpensive substitutes for vacuum pumps. In most applications, motor-driven vacuum pumps [...]

Vacuum generators or vacuum pumps? A parade of vacuum generators has come to market over the past several years. Sometimes called ejectors, these devices direct a compressed air stream through [...]

To select a vacuum pump, first thoroughly understand what you need your vacuum system to do. Just as important, you must also know the impact the selected vacuum system will [...]

Knight Industries of Auburn Hills, MI, incorporated Piab Vacuum Products' multicharacteristic ejector pumps into their windshield-handling systems upon the recommendation of MRM Inc. The ejector pumps, which replaced compressed-air-driven vacuum pumps, leads to higher efficiency by facilitating greater control over vacuum and air flow. It also lowered air consumption from 34.5 million scf. to 1.8 million scf., Energy efficiency is a growing concern inside today's automobile manufacturing plants, and it proved to be a key consideration in the design of a next-generation windshield-transfer system, according to David [...]
