Discover The Advanced Efficiency Of Duplex Strainers At Purple Engineering
Designed to cater to systems that demand continuous operation, our Duplex Strainers ensure your processes run smoothly without the need for shutdown during basket cleaning.
Our duplex filters are the backbone of efficient fluid handling. They are ideal for applications such as cooling water systems, compressors, condensers, fire lines, fuel lines, fuel lines, lubrication systems, and both salt and freshwater systems. Note that they are not recommended for steam service.
Innovative Design For Optimal Performance
Our Duplex Basket Strainers stand out with their use of 3-way balls as diverter valves, featuring PTFE seats for bubble-tight shut-off. This design eliminates costly leaks and allows for true inline maintainability. With a two-part body casting, all valve components are easily accessible for maintenance without removing the strainer from the line. For ease of operation, gear operators are standard on 4" & 6" units, facilitating effortless changeovers. Models equipped with handles indicate the chamber in use, enhancing safety by preventing accidental opening and simplifying access for servicing.
