Duomax Vault™ Basket Strainer Series: Heavy-Duty,
High-Capacity Pipeline Security
When you are running a continuous industrial facility, unmanaged pipeline debris is a constant threat to your bottom line. Left unchecked, solid particulates and loose corrosion products can score pump impellers, choke control valves, and damage downstream processing units.
For permanent operations that require maximum dirt-holding capacity and straightforward maintenance access, we have introduced our new range of products: the Duomax Vault™ Basket Strainer.
Designed to serve as a robust defensive barrier, this series handles both coarse and fine filtration tasks. By providing a massive internal reservoir for trapped solids, it ensures your system maintains a steady flow rate over extended operational cycles without requiring frequent shutdowns.

Precision Welded Construction and Bypass-Free Safety
A reliable basket strainer requires an absolute mechanical seal between the internal filter element and the main pressure vessel. If the basket fits loosely, contaminated fluid will seep around the edges, letting damaging debris travel straight to your sensitive machinery.
The Duomax Vault™ Basket Strainer eliminates this risk through high-precision manufacturing:
- Seamless Fabricated Housing: Every unit is constructed using high-grade seamless tubes as standard. Two rugged nozzles equipped with welding neck flanges are precisely welded onto the base pipe, aligning perfectly with your existing installation layouts.
- Individually Tailored Seating: We customize the interface between the basket insert and the housing for every single unit we build. This tailored fit guarantees a tight mechanical seal, ensuring completely bypass-free filtration under full operating pressures.
- Straightforward Extraction: When it is time to service the unit, operators can access, remove, and wash the internal basket quickly through a dedicated top-opening service hatch.
Ergonomic Features for Larger Nominal Sizes
As pipeline diameters grow, handling heavy steel components can become a safety hazard and a maintenance bottleneck. For our larger Duomax Vault™ Basket Strainer models, we offer a range of mechanical handling options to make servicing a one-person job:
- Pivoting Devices and Hinges: Instead of requiring a crane to lift away a heavy blind flange cover, our integrated davit arms or heavy-duty hinges allow technicians to swing the top cover open smoothly and safely.
- Lifting Eyes and Handles: The service covers and individual internal baskets can be equipped with robust lifting eyes and ergonomic handles, ensuring safe rigging practices during routine cleanings.
Flexible Configurations for Cleaning and Monitoring
The Duomax Vault™ is built to adapt directly to your plant’s specific operational layout, offering several auxiliary configurations to streamline your daily maintenance routines.
Advanced Drainage and Flushing Layouts
To keep cleanings as mess-free as possible, the top blind flange can be configured with specialized flushing nozzles, while the bottom of the housing can feature residual emptying nozzles. We customize these connections to match your plant standards, offering:
- Socket connections with threaded pipe plugs for simple setups.
- Weld-on ends or full flange connections integrated with a dedicated shut-off valve for fast, controlled blowdowns.
Real-Time Differential Pressure Monitoring
To take the guesswork out of your maintenance schedule, we provide complete instrument integration. You can specify your units with standard connecting sleeves, pre-routed measuring lines, specialized valve blocks, or fully integrated differential pressure gauges. This allows your control room to monitor exactly how full the basket is in real time, helping you plan cleanings well before a clogged screen triggers a flow restriction.

Frequently Asked Questions (FAQ)
1.What makes a basket strainer better for permanent plant operations than a Y-strainer?
A basket strainer is designed with a significantly larger internal chamber, giving it a much greater dirt-holding capacity than a compact Y-strainer. Because it can store a heavy volume of solids before the pressure drop spikes, it is ideal for continuous, permanent operations. Additionally, the service opening is located at the top of the unit. This allows operators to easily lift the basket straight up and out for cleaning without draining the entire housing, making maintenance far cleaner and faster.
2.How does the Duomax Vault™ ensure that no unfiltered fluid bypasses the basket?
Many standard off-the-shelf strainers rely on loose, universal clearances where the basket rests inside the body. Under high pressures, fluid can easily slip through those tiny gaps, carrying harmful debris downstream. Every Duomax Vault™ housing and internal basket insert is individually machined and matched during production. This tailored, high-tolerance mechanical seat ensures a tight, flush seal that forces 100% of the process fluid through the mesh.
3.Why are pivoting devices or hinges recommended for larger nominal sizes?
On larger pipelines (typically 8 inches and above), the top blind flange cover becomes incredibly heavy, often weighing over 100 pounds (45 kg). Unbolting and lifting a heavy cover manually poses a serious injury risk to maintenance crews and often requires rigging a temporary crane. Adding an integrated pivoting davit arm or heavy-duty hinge allows a single operator to safely unbolt and swing the massive cover out of the way, drastically reducing your maintenance downtime.
4.What is the purpose of the flushing and residual emptying nozzles?
These auxiliary connections make cleaning the strainer safer and more efficient. Before opening the top cover to remove a debris-laden basket, operators can open the residual emptying valve at the bottom of the vessel to completely drain hazardous or hot process fluids. The top flushing nozzles allow you to hook up a clean water or solvent line to wash down the internal basket and housing walls before pulling the element, minimizing operator exposure to the process media.
5.Can I use the Duomax Vault™ for both coarse and fine filtration?
Yes. The structural strength of the inner basket core allows it to support a wide range of filtration requirements. For coarse filtration, we utilize a rugged, heavy-gauge perforated metal plate basket. For fine filtration, we line that same heavy-duty metal core with a fine, precision-woven wire mesh. This multi-layer construction ensures that even when filtering fine particles down to the micron level, the basket can easily withstand the high fluid forces without buckling or tearing.
