Duplex basket strainers are pipeline strainers used in applications where the process cannot be stopped to clean the baskets. Duplex basket strainers are available in cast iron, cast steel, cast stainless steel, aluminum bronze as well as fabricated carbon steel, stainless steel and other alloys to handle almost every application.
Fabricated Duplex Basket Strainers
Duplex basket strainers are used where increase basket sizes are desired. Fabricated basket strainers can be designed to fit custom dimensions. This is particularly beneficial when replacing an existing strainer, thus keeping replacement costs low.
• Fabricated carbon steel strainer body with bolted style cover
• 304 stainless steel basket with perforated (1/32”, 1/16”, 1/8”, 5/32” openings)
• Butterfly valve with cast iron body Buna-‘N’ seats, ductile iron disc, and stainless steel stem
• Lever operated valves with inter-connected linkage
• Positive seal valving
• Design pressure 150 psig @ 150°F
• Welded to ASME Section IX, certified welders
• Complete package is hydrostatically tested

Latch bolt closures
Basket material of 316 stainless steel, brass, monel, and others
Mesh lined basket – 20 x 20 to 500 x 500 mesh In-line connection arrangement – Model 544
In-Line Duplex Basket Strainer
The Model 544 inline duplex basket strainer is used when the existing piping cannot be offset.
Cast Duplex Basket Strainers
Engineered for optimal flow patterns, Cast Duplex Strainers, divert the pipeline flow from one basket to the other allowing the inactive basket to be cleaned without shutdown.
No special tools are needed to operate the handle or remove the straining element reducing in-line maintenance.
Duplex Strainers are available with threaded and flanged ends in a variety of materials. All cast iron and carbon steel units are epoxy painted to resist rust. They can be fitted with virtually any configuration of perforation or mesh lined straining elements. Straining elements can also be constructed from special materials such as Alloy 20.
