TwinFlow Pro Fabricated Dual Basket Strainer
Continuous Flow, Zero Downtime
The TwinFlow Pro Fabricated Dual Basket Strainer
In industrial processing, stopping production to clean a clogged filter isn’t just inconvenient it is expensive. When your pipeline requires uninterrupted flow but your fluid contains solids that need filtering, a standard single strainer forces a tough choice: shut down the line or risk equipment damage.
The TwinFlow Pro Fabricated Dual Basket Strainer eliminates that compromise. Engineered for continuous operation, this duplex system uses a reliable valve mechanism to switch flow smoothly from one basket chamber to the other. You can isolate, clean, and service the offline basket safely without dropping line pressure or stopping your process for a single second.

Built to Fit Your Pipeline, Not the Other Way Around
Cast strainers limit you to standard sizes, fixed pressure ratings, and rigid material choices. Because the TwinFlow Pro is fully fabricated, we build it to match your exact application requirements.
Whether you are managing high-volume cooling water, viscous polymers, or aggressive chemicals, our fabricated design allows for precise customization:
- Tailored Dimensions: Face-to-face dimensions and nozzle orientations can be altered to fit into tight or existing piping layouts without costly field modifications.
- Material Versatility: Available in carbon steel, stainless steel, and high-performance alloys to handle corrosive fluids and extreme temperatures.
- Engineered for Pressure: We design and manufacture to meet specific design pressures and piping codes, ensuring long-term structural integrity.
- Optimized Basket Design: Choose from a wide selection of perforation sizes and mesh linings to achieve the exact micron rating your downstream equipment demands.
How It Works: Simple, Safe Operation
The core benefit of the TwinFlow Pro is its straightforward, mechanical dependability.
- Dual Chamber Design: The unit features two identical chambers, each housing a high-capacity strainer basket.
- Diversion Valve Assembly: A integrated changeover valve system controls the fluid path.
- Seamless Switching: When the active basket becomes loaded with debris, a simple turn of the valve diverts the raw fluid to the clean chamber.
- Safe Maintenance: The dirty chamber is isolated and depressurized, allowing operators to safely open the cover, clean the basket, and replace it so it is ready for the next cycle.
Where the TwinFlow Pro Excels
The TwinFlow Pro is designed for heavy-duty industries where process continuity is critical.
It is frequently utilized in:
- Power Generation: Protecting condenser tubes and cooling water systems from debris.
- Chemical Processing: Filtering raw materials and protecting sensitive pumps and meters.
- Water & Wastewater Treatment: Straining intake water and protecting downstream membranes.
- Oil & Gas: Handling fuel lines, lubrication systems, and processing fluids.
- Pulp & Paper: Managing process water and white water filtration.
Why Choose a Fabricated Solution?
When you invest in a fabricated dual strainer like the TwinFlow Pro, you are buying a piece of equipment built for your specific process conditions. Unlike cast alternatives, fabrication allows for thicker corrosion allowances, custom vent and drain configurations, and specialized non-destructive testing to match your plant’s safety standards. It provides a robust, reliable shield for your pumps, nozzles, heat exchangers, and analytical instruments
Frequently Asked Questions
Q. What is the main advantage of a fabricated strainer over a cast strainer?
Cast strainers are poured into fixed molds, meaning you are limited to standard dimensions and material thicknesses. Because the TwinFlow Pro is fully fabricated (welded from raw plates and pipes), we can customize the nozzle positions, face-to-face dimensions, and pressure ratings to fit your existing piping perfectly. Fabrication also allows us to build with specialized alloys that are difficult or impossible to cast.
Q. Does the flow drop when switching between baskets?
No. The changeover valve mechanism is designed with a slight overlap. As you switch the valve, the clean chamber opens before the dirty chamber fully closes. This guarantees continuous flow and prevents dangerous pressure spikes or flow starvation downstream.
Q. How do operators know when it is time to clean a basket?
We recommend installing a differential pressure gauge across the inlet and outlet. As debris collects in the active basket, the pressure drop increases. Typically, a differential pressure of 5 to 10 psi indicates that it is time to switch to the clean chamber and wash the dirty basket.
Q. What pressure ratings and design codes are available?
Because each unit is fabricated to order, we design to your specific design pressures, ranging from standard atmospheric lines to high-pressure systems. We build and test our strainers in strict accordance with major industrial piping and pressure vessel codes, including ASME Section VIII and B31.3.
Q. Can the TwinFlow Pro handle highly corrosive fluids?
Yes. We select construction materials based entirely on your fluid properties. While carbon steel is excellent for non-corrosive fluids, we routinely fabricate the TwinFlow Pro from 304/316 stainless steel, duplex stainless steels, or high-nickel alloys for aggressive chemical, marine, or wastewater applications.
Q. What maintenance is required for the changeover valve?
The changeover valve is built for heavy industrial use and requires minimal maintenance. Regular inspections should include checking the valve seals for wear and lubricating the mechanical linkage or lever mechanism to ensure smooth operation during changeovers.
