Eaton model 90 simplex strainers are custom fabricated per your specificaitons wheras our other simplex strainers are based upon either a cast or molded body, the model 90 is fabricated from pipe and plate materials to satisfy specific design criteria such as corrosion allownace, ASME code stamp, number of nozzles, their location and type and specific straining ratios.
Our website illustrates 150# and 300# designs made of carbon steel and 316L stainless steel, however we offer higher pressure class versions and exotic alloys for material of construction when required.
The Eaton model 90 basket strainer is provided with either a bolted cover or a hinged "quick opening cover" (using eyebolts to hold the cover down). The hinged quick-opening cover design eliminates the need for a cover lift davit assembly and reduces the lifting force enough to enable a single operator to open the cover to access the basket.
Cover lift davits are an option for the larger size strainers which might require it; once you exceed a 24" model 90 simplex strainer the hinged quick-opening cover is no longer an option because the cover weighs too much.
Another standard option are mounting legs. Eaton model 90 basket strainers can be manufactured with flat bottoms to be supported by a mounting pad the customer supplies or we can attach non-adjustable legs to provide a specific inlet/outlet nozzle height above grade.
Other customizations include offset nozzles; perhaps your application benefits from nozzles that are tangential to each other whenthe inlet and outlet are located on the same side - custom fabricated basket strainers enable you to customize the design to fit your specific requirements.
