Miniature Inert Solenoid Pump Designed for Flexibility and Cost Savings
The Lee Companys new LPM Series Inert Solenoid Pump was designed to offer greater design flexibility and significant cost savings to the medical and scientific industries.
The LPM pump features a revolutionary port head design that allows tubing connections and manifold mounting. This enables the designer to test the fluidic system using connections to soft 1/16" tubing, and then once the system design has been finalized, the same pump can be manifold mounted using...
The LPM pump features a revolutionary port head design that allows tubing connections and manifold mounting. This enables the designer to test the fluidic system using connections to soft 1/16" tubing, and then once the system design has been finalized, the same pump can be manifold mounted using standard O-rings.
Available in standard 10 µL and 25 µL models, the pump features low power consumption and a contoured end cap which provides secondary connector retention and is compatible with standard AMP connectors.

The Difference Between Calibrated Orifices and Holes
Engineers tasked with managing fluid flow talk about both holes and calibrated orifices, but they are two distinct entities. A hole can beany opening, but a calibrated orifice is specially designed to precisely control fluid flow. Consequently, its diameter, length, and geometry are critical to its intended operation. With the right design, an orifice can provide the desired control over fluid flow rates and pressure spikes.
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.
