Project Description

Fabricated Duplex Strainers

Fabricated duplex strainers (double basket strainers) are used when the flow or process cannot be shut down and must continue to flow. Thus, duplex strainers allow you to shut one basket for cleaning while the other is still in operation. Moreover, double basket strainers are normally used where larger amounts of trash/solids need to be removed. The screen is in the shape of a basket and removed from the top of the fabricated duplex strainer. Fabricated duplex strainers can come with a blow-off connection for manual or automatic cleaning.

Duplex Strainers

The main application for duplex strainers is in fluid handling systems such as cooling water, fire lines, hydrocarbon, fuel lines, freshwater, pump suction, compressors, and lubrication systems. A fabricated duplex strainer’s body can be casting or fabricated material. Always check material compatibility with the process. Screens should be sized to meet the perforations, and mesh requirements.    

Fabricated duplex strainers gaskets, end connections, and blow-off connections should be part of the sizing equation. Contact us for more information or for a quote. Read about industrial strainers.
