This company’s new HollowStream liquid atomizing spray nozzle (photo) provides a hollow-cone spray pattern, and features a tangential flow design. The design is vaneless, with wide-open internal features, to resist clogging while producing a uniform distribution in a ring pattern…
As various rotating machinery throughout fiber-processing operations experience extremely harsh and demanding environments, it is often difficult to manually retrieve oil samples. Maintaining an adequate surveillance of lubrication properties against harmful effects can prove very challenging. This company’s oil-monitoring system…
With new manufacturing improvements to its standard plated paddle agitator (photo), this company can speed up lead times on its 30-in. dia. and smaller-sized horizontal mixers. The new plated paddle agitators are manufactured with the paddle and arm sections cut…
Canned motor pumps (CMPs) are designed to prevent emissions by eliminating the mechanical seal. Provided here is an overview of CMPs, along with information on common uses Emissions from process equipment not only pose safety and environmental risks, they also…
Selecting an effective system for controlling air pollution can help to achieve balance between environmental stewardship and industrial productivity Air pollution is an ongoing worldwide concern that impacts people and ecosystems across the globe. The emission of pollutants like particulate…
Adhering to API 682 guidelines will create safe, efficient and effective mechanical-seal supports in pumping systems In the 1980s, mechanical seals became the most frequently used sealing technology in petroleum refineries and chemical plants. The American Petroleum Institute (API; Washington,…
