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.

Frequently Asked Questions

Duplex Strainers are advanced filtration devices designed for systems that require continuous operation without interruption for cleaning or maintenance.

Unlike simplex strainers, which have a single basket and need to be shut down for cleaning, Duplex Strainers consist of two parallel strainer baskets housed within a single body.

This design allows the flow to be diverted from one basket to the other, enabling one to be cleaned while the other continues to filter, thus ensuring uninterrupted operation. They are ideal for critical applications where continuous flow is essential, such as in cooling water, fuel lines, and lubrication systems.

Key Functions of Strainers

Particle Removal

Industrial strainers have been designed to capture and remove solid particles such as dirt, debris, rust, scale, and other impurities from liquids like water, oil, chemicals, or gases.

Extended Equipment Life

By removing solid contaminants, industrial strainers contribute to the longevity and efficient operation of industrial equipment. Reduced wear and tear on components leads to longer maintenance intervals and a longer overall lifespan for the equipment.

Maintenance Reduction

Regular maintenance and cleaning of industrial equipment is definitely time-consuming and costly. Strainers help reduce the frequency of maintenance activities by preventing the accumulation of debris in the system.

Equipment Protection

The main purpose of using an industrial strainer is to protect downstream equipment and components from damage caused by particles present in the fluid. For example, strainers help prevent damage to pumps, valves, heat exchangers, and other critical components by ensuring that only clean fluid passes through pipelines.

Process Efficiency

Uninterrupted fluid flow without the obstruction of contaminants improves the overall efficiency of industrial processes. This is particularly important in industries such as water treatment, petrochemicals, pharmaceuticals, and manufacturing.
