Miller-Leaman, Inc. introduces their patented stainless steel Thompson Strainers. Available in Type 304 and Type 316 stainless steel, the unique strainers feature a large conical screen element, offering substantially more screen surface area versus traditional y-strainers, basket strainers, etc. The strainers are available with a large variety of screen mesh options, ranging from large perforated hole-openings down to approximately 50-micron.
As water enters the bottom of the strainer housing and flows upward, heavier debris and particulate is accelerated downward (away from the conical screen) into the large debris reservoir at the base of the strainer. The particulate is then flushed from the reservoir via the debris flush port. Due to the large amount of screen surface area, all models operate with a minimal pressure drop; less than 1-PSI (when clean). The strainers can be customized to fit the specific requirements of the project.
In addition, the strainers can be outfitted with optional Instrumentation Packages. This includes a Pressure Differential Alarm Package (PDA) which will set off an audible/visual alarm when the strainer needs to be serviced and an Automatic Timer Flush Package (ATF-EA-1.5) which is programmed to automatically open the flush port of the strainer on a periodic basis.
