In low-temperature conditions, the use of compatible sealing materials is essential for leak-tight operation and proper functionality of pressure-regulating devices Harsh, frigid conditions are among the most challenging industrial environments (Figure 1) for fluid-handling applications. At these temperatures, it is…
Pumping hazardous chemicals requires specific shaft-sealing technologies to ensure containment and reliability Hazardous chemicals are defined by the Environmental Protection Agency (EPA; Washington, D.C.; www.epa.gov) as those that are potentially harmful to human health and the environment. Existing as gases…

Also known as 2-PH and 2-propylheptyl alcohol, 2-propylheptanol is a branched fatty alcohol, primarily used in the production…
Selecting the best air mover for a bulk-solids pneumatic-conveying application is a critical design decision. Provided here is information on three classes of air movers when dilute-phase pneumatic conveying is required In a typical bulk-solids pneumatic-conveying system, an air mover…
Within the chemical process industries (CPI), the need to design safety systems to prevent process failures from occurring, or to control them when they do, is well recognized, as is the importance of having confidence in the safety systems that…
Understanding what technology is available is a first step towards selecting the right pump for metering applications Reciprocating metering pumps are problem solvers for difficult fluid-handling tasks and applications. Their main function is the metering of a precise fluid volume…
