FRP Vessel 844 2.5″ – 10 Bar Composite Pressure Tank

The FRP vessel 844 2.5″ is a compact and strong pressure tank that supports various water treatment needs. Because it uses fiberglass-reinforced plastic (FRP) with a seamless polyethylene liner, the tank resists rust and holds up under chemical exposure. Its 2.5″ threaded media opening makes it easy to add or change filter media, and the 10 bar (150 psi) pressure rating helps it work in systems with booster pumps or higher pressure water lines. Therefore, this tank suits both home and light commercial use. (puritech.co.za)

Furthermore, its compact build fits in tight spaces, and its composite design cuts down on maintenance. Because of this, the FRP vessel 844 2.5″ delivers reliable performance over time.

Key Features & Benefits

• Sturdy Composite Build

  • The FRP body and seamless liner protect against rust and chemical attack. As a result, the vessel lasts longer than many metal alternatives and stays strong even with frequent use.

• 2.5″ Opening for Easy Access

  • Because the tank uses a 2.5″ threaded opening, you can load or replace media with less effort. Moreover, the opening fits standard top-mount valves and distributors, so installation stays simple.
• High Pressure Rating
  • The FRP vessel 844 handles pressures up to 10 bar (~150 psi). Therefore, it works well in systems where higher water pressure and booster pumps are common.

• Works with Various Media

  • You can fill this tank with different types of media for specific needs:
    • Sand — for sediment removal
    • Activated carbon — for chlorine, taste, and odour removal
    • Ion-exchange resin — for water softening
    • Multimedia blends — for deeper filtration
  • This flexibility helps tailor the system to your water quality goals.

• Compact and Easy to Install

  • Because this vessel is lighter and more compact than larger tanks, it fits into tight spaces and installs easily without heavy lifting. In addition, it works well with standard fittings and valves.

Technical Specifications

How It Works

The FRP vessel 844 2.5″ holds the chosen media inside its pressure-rated body. Water flows through this media under system pressure, which helps remove or reduce contaminants based on the media type. For example, sand removes particles and dirt, while activated carbon captures chlorine and organic molecules. Because the composite tank resists both corrosion and chemical stress, you get a longer service life with less need for replacement.

In addition, the 2.5″ opening lets you install or change media more easily than narrower access points. As a result, this vessel suits systems that see frequent media changes or upgrades.

Recommended Applications

• Domestic Filtration Systems — Provides a reliable housing for sediment and carbon filters.
• RO Pre-Treatment — Holds pre-filter media to protect reverse osmosis membranes.
• Water Softening Support — Houses resin for ion exchange and hardness removal.
• Small Commercial Systems — Supports higher pressure and booster setups.
• Point-of-Entry (Whole-House) Systems — Ensures whole-house water quality improvements.

Because it works well with both standard plumbing and common control valves, this tank fits easily into existing systems and future upgrades.

Installation & Maintenance Tips

1. Place on a stable, level surface before media loading to prevent uneven settling.
2. Match the 2.5″ opening with compatible valves and distributors for a secure fit.
3. Flush media before first use to remove dust or fines.
4. Inspect seals and connections after pressurizing to make sure there are no leaks.

These simple checks help ensure the system runs smoothly and prolong vessel life.

Conclusion

The FRP vessel 844 2.5″ offers a compact, corrosion-resistant solution for a wide range of water treatment applications. Because it supports high pressure and works with multiple media types, it delivers dependable performance in filtration, softening, and pre-RO systems. In addition, its easy media access and straightforward installation make it a practical choice for both residential and light commercial water systems.
