Reliable Fire Protection Foam Bladder Tank
The foam bladder tank, as a core component of pressure-type foam proportioning systems, efficiently mixes foam concentrate with water at a precise ratio to generate effective fire-extinguishing foam. Comprising a heavy-duty outer pressure vessel and a flexible inner elastomeric bladder, it isolates water and foam concentrate while transferring water pressure seamlessly. When paired with a ratio controller (e.g., Venturi-type), it forms a balanced system that maintains stable 3% or 6% mixing ratios even under variable flow and pressure conditions, making it ideal for diverse hazard scenarios.

Reliable Fire Protection Foam Bladder Tank
The foam bladder tank, as a core component of pressure-type foam proportioning systems, efficiently mixes foam concentrate with water at a precise ratio to generate effective fire-extinguishing foam. Comprising a heavy-duty outer pressure vessel and a flexible inner elastomeric bladder, it isolates water and foam concentrate while transferring water pressure seamlessly. When paired with a ratio controller (e.g., Venturi-type), it forms a balanced system that maintains stable 3% or 6% mixing ratios even under variable flow and pressure conditions, making it ideal for diverse hazard scenarios.
Core Structure & Working Principle
The outer vessel is typically fabricated from carbon steel (or stainless steel for corrosive environments) to ASME Section VIII standards, with a design pressure of 1.2 MPa and hydrostatic test pressure up to 2.1 MPa, ensuring durability and safety. The inner bladder, made of high-performance elastomeric materials (e.g., Hypalon over polyester), acts as a barrier to prevent pre-mixing of fluids. During operation, pressure water flows through the ratio controller, creating a pressure drop. A portion of water enters the tank to compress the bladder, forcing foam concentrate out to mix with the main water stream at the calibrated ratio. Post-use, the bladder refills automatically, ready for the next activation.
Key Specifications & Customization
Available in vertical/horizontal configurations and capacities ranging from 190L to 11,300L (50–3,000 gallons), the tank accommodates various project scales. It supports foam concentrates including AFFF (Aqueous Film-Forming Foam), AR-AFFF, and protein foam, suitable for Class B flammable liquid fires (e.g., oil depots, chemical plants) and multi-hazard protection systems. Standard features include pressure gauges, safety valves, ball valves, and level indicators; optional add-ons like manholes, platforms, thermal expansion relief valves, and insulation enhance adaptability to harsh environments. Surface treatments include fire-red polyurethane coating (RAL 3000) for exterior and coal tar epoxy for interior, ensuring corrosion resistance.
Certifications & Applications
Our foam bladder tanks hold key certifications such as UL Listed, CE marking, and CCCF, complying with international fire safety standards. Widely applied in oil & gas terminals, refineries, power plants, shipyards, and underground parking lots, it delivers reliable fire suppression with minimal maintenance-no moving parts reduce operational complexity, while the bladder's long service life lowers lifecycle costs.
