Flower Strainer – Heavy-Duty Water Distributor Set for Commercial RO Plant Vessels (21" & 24")
The Axtron Flower Strainer is a heavy-duty water distributor set built for large commercial FRP pressure vessels — the kind used in Pakistan's bigger commercial RO plants and water treatment setups, typically the 21" and 24" diameter tanks that smaller multiport valve riser assemblies simply aren't designed to handle. Where a single center riser tube is enough for smaller commercial tanks, vessels of this size need a proper radial distribution system to get even flow across the entire tank — which is exactly what this set provides.
Why Vessels This Size Need a Proper Distributor
Inside any sand, carbon, or resin-filled FRP tank, water needs to move evenly through the full cross-section of the media bed — both during normal service flow and during backwash. In smaller tanks, a single center riser with a strainer sleeve is enough to achieve this. But as tank diameter grows past a certain point, a single riser can't spread flow evenly across the whole bed on its own; water tends to channel through the path of least resistance, leaving parts of the media bed poorly cleaned during backwash and reducing overall filtration effectiveness over time.
A radial "hub and lateral" distributor — the flower/six-claw design in this set — solves that by spreading multiple slotted arms out across the tank's diameter, so water enters or exits from many points at once rather than one central point. This gives a uniform, low-impact flow across the entire media bed, protects the media from being disturbed unevenly, and prevents fine media particles from escaping into the water line or downstream equipment.
What's in this Flower Strainer Set
This is a complete kit — not just a single distributor head. It includes:
- 1x Radial (Six-Arm) Flower Distributor — Slotted ABS arms that spread across the tank diameter for even flow distribution/collection.
- 1x Vertical Riser Strainer — A single slotted strainer tube for the tank's secondary connection point.
- Connecting Fittings — Elbow and coupling fittings to plumb the distributors into the tank's top and bottom ports.
- Bulkhead Mounting Assembly — Threaded flange, locknut, and gasket for a sealed screw-in installation through the tank wall.
- 1x Installation Wrench — A dedicated spanner for tightening the locknut assembly during installation.
Key Features
- Radial Flower/Six-Claw Design — Multiple slotted arms distribute flow evenly across large tank diameters.
- Complete Top & Bottom Setup — Includes both a radial distributor and a riser strainer to cover both connection points in the tank.
- ABS Construction — Corrosion-resistant and rated for continuous water treatment duty.
- Screw-In Bulkhead Fitting — Threaded, gasketed connection with a dedicated installation wrench for a secure, leak-free fit.
- Media Retention — Fine slots hold back sand, carbon, or resin media while allowing water to pass freely.
Tank Compatibility
In Pakistan's commercial water treatment market, this set is most commonly used on 21" and 24" diameter FRP vessels (the 21"×62" and 24"×72" tank sizes typical of heavy commercial RO plants and water treatment stations). The manufacturer's component packaging separately lists reference dimensions of 300×900mm and 600mm for the individual distributor pieces — those are the manufacturer's own labeled test/reference sizes, while the 21"/24" range reflects how this set is actually deployed in the field here.
Applications
- Heavy Commercial RO Plant Pretreatment Tanks — Sand, carbon, or multi-media filtration vessels ahead of the RO stage.
- Commercial Water Softener Tanks — Even distribution across large resin beds.
- Industrial & Institutional Water Treatment — Factories, large-scale water shops, and bulk filtration stations running 21"–24" vessels.
Why Axtron?
Axtron Pakistan has supplied water filtration and RO plant components since 2005, with offices in Lahore, Multan, and Bahawalpur and a network of 500+ retailers nationwide. This flower strainer set is sourced specifically for the vessel sizes Pakistan's commercial RO plant operators actually use, not just generic manufacturer-listed sizes.
Conclusion
If you're building or maintaining a large commercial RO plant, sand filter, or softener tank on a 21" or 24" diameter vessel, the Axtron Flower Strainer gives you a complete, ready-to-install distribution system built for even flow and reliable long-term performance — without needing to source individual fittings separately.

11. FAQ Section (add via Rank Math's FAQ block for FAQPage schema)
Q1: What is a "flower strainer" used for?
A1: It's a water distributor system installed inside large commercial FRP tanks (sand filters, carbon filters, softeners). The radial "flower" arms spread water evenly across the full tank diameter during service and backwash, preventing channeling and holding filter media in place.
Q2: What vessel sizes does this fit?
A2: In Pakistan's commercial market, it's most commonly used on 21"×62" and 24"×72" FRP vessels — the standard heavy commercial tank sizes for RO plant pretreatment and softener systems.
Q3: Is this a single distributor or a complete set?
A3: It's a complete set — a radial six-arm flower distributor, a riser strainer, connecting fittings, a bulkhead mounting assembly, and an installation wrench, all included.
Q4: What is it made of?
A4: ABS plastic, chosen for corrosion resistance and durability under continuous water treatment use.
Q5: Can this be used for a water softener tank as well as a sand filter?
A5: Yes — this type of distributor is commonly used across sand filters, carbon filters, and softener resin tanks of matching vessel size.
Q6: Do you deliver this across Pakistan?
A6: Yes — Axtron delivers nationwide, including Karachi, Lahore, Islamabad, Rawalpindi, Faisalabad, and Multan, with physical offices in Lahore, Multan, and Bahawalpur.
