What type of strainer consists of one or more fine mesh screens or perforated metals?

A simplex strainer is designed with one or more fine mesh screens or perforated metals, which function to filter out solid particles from fluids. This type of strainer is typically utilized in applications where there is a need to protect pumps and other equipment from larger particles that could cause wear or damage. The design allows for easy removal and cleaning of the screen or element, making maintenance straightforward.

In contrast, other types of strainers serve different purposes or feature alternative designs. For example, a duplex strainer contains two chambers, allowing for continuous operation while one chamber is cleaned, but it does not inherently mean that it uses fine mesh screens exclusively. A media filter operates on a different principle, using a bed of filtering media to remove particulates, which may not necessarily be metal screens. Lastly, a coarse strainer uses larger openings to filter out bigger debris, which means it wouldn’t provide the same level of filtration as a simplex strainer with fine mesh screens.
