FRP Vessel 1035 2.5″ – 10 Bar Composite Pressure Tank | Monster Mechanical

The FRP vessel 1035 2.5″ is a strong and cost-effective composite pressure tank that plays a key role in many water treatment systems. It uses fiberglass-reinforced plastic (FRP) and a seamless polyethylene liner to resist corrosion and chemical damage. Because of this, it delivers long-lasting performance in both commercial and residential setups. Additionally, its 2.5″ top opening makes it easy to install media and connect top-mounted valves. Most importantly, it handles pressures up to 10 bar (150 psi), so it works well in systems that use booster pumps or higher inlet pressure.

Whether you are building a new system or upgrading an existing one, this vessel supports reliable water flow and efficient water treatment with minimal maintenance.

Key Features & Benefits

• Corrosion-Resistant Composite Build
  • This tank uses FRP and a polyethylene inner liner. Therefore, it resists rust, chemical wear, and long-term water exposure. As a result, you get a tank that lasts longer than many metal alternatives.
• 2.5″ Top Opening for Access
  • The 2.5″ threaded opening lets you load and service filter media easily. Moreover, it works with a range of top-mount valves, which simplifies installation.
• High Pressure Rating
  • Because this vessel supports up to 10 bar (150 psi), it works well in systems with higher pressure levels that include booster pumps, multi-stage filtration, or larger flow demands.
• Compatible with Various Media Types
  • You can fill this tank with many types of media, such as:

    • Sand for sediment and particle removal

    • Activated carbon for taste and odour improvement

    • Ion-exchange resin for water softening

    • Multimedia blends for broader filtration

  • This versatility makes the tank a good choice for different water quality challenges.
• Compact and Easy to Handle
  • With a smaller footprint and lightweight design, the FRP vessel 1035 2.5″ installs easily even where space is limited. In addition, it requires less effort and time during setup compared to heavier steel tanks.

Technical Specifications

How It Works

The FRP vessel 1035 2.5″ acts as a media container for water purification systems. First, you add the right media for your needs. Then, water flows through this media under system pressure. For example, sand removes particles, carbon reduces chlorine and odour, and resin softens hard water. Because this tank uses non-corroding materials, it resists wear and rust even after many cycles of use. Moreover, the 2.5″ opening gives you easy access for media filling and valve installation.

As a result, the vessel works well in systems that demand both durability and flexibility.

Applications

• Water Filtration Systems — Removes sediments and protecting finer filters downstream.
• Reverse Osmosis Pre-Treatment — Houses pre-filters to help preserve membrane life.
• Water Softening Support — Holds resin for hardness reduction.
• Residential Water Treatment — Offers reliable service for whole-house treatments.
• Commercial and Light Industrial Water Systems — Works well with higher pressure setups.

Because of its design and pressure rating, this tank fits well into many system types.

Installation & Maintenance Tips

1. Place the tank on a stable, level surface before adding media.
2. Match the 2.5″ top opening with compatible valves or distributors.
3. Flush media before first use to remove dust or fines.
4. Check all fittings and seals after pressurization to avoid potential leaks.

Following these steps helps keep the tank operating effectively and extends its service life.

Conclusion

The FRP vessel 1035 2.5″ brings together corrosion resistance, robust pressure handling, and flexible media support in one compact and easy-to-maintain tank. Because it resists rust and chemical damage, and because it handles higher pressures safely, it offers reliable performance across different water treatment applications. As a result, it remains a strong choice for filtration, softening, and pre-RO treatment systems in both homes and facilities.
