Key Considerations for Selecting a Medical Pump
Newcomers to medical device design may think that pressure and flow rate are sufficient parameters to consider when it comes to selecting a pump. While this may be the case in some industrial applications, medical device requirements are a bit more demanding. A thorough review of the selection criteria for a medical pump is required to ensure the correct pump is chosen for every application.

Adapting Fluid Control Components for Hydrogen Applications
Although aviation is a relatively small contributor to global greenhouse emissions, it is also one of the fastest-growing. The major airline companies are aware that the goal of minimizing their carbon footprint is tied to the eventual elimination of the use of fossil fuels. Many of the industry’s major airlines have publicly announced plans to completely phase out carbon-based jet fuels from their operations in favor of a clean-burning alternative—hydrogen.   Transitioning from fossil fuels to hydrogen will require modifications to or replacement of current technologies that control liquid fuel. As engineers assess the impact of these significant modifications, it is important that they address the unique challenges associated with controlling pneumatics in general and hydrogen in particular. This article addresses those challenges associated with the design of components used to control fuel between the storage tank and the combustion chamber of an aircraft, such as flow restrictors, valves, and filters.
