Outdoor Pillar Fire Hydrant BS750
The BS750 is an ordinary outdoor pillar fire hydrant BS750—a foundational component of municipal and industrial fire protection systems, designed to provide high-flow water supply for initial fire suppression and fire truck water intake. Unlike indoor hydrants (smaller, wall-mounted), outdoor pillar hydrants are installed above-ground in open areas (roadsides, factory yards, commercial parks) for unobstructed access, even in large-scale emergency scenarios.

CA-FIRE Outdoor Pillar Fire Hydrant BS750
The BS750 is an ordinary outdoor pillar fire hydrant BS750-a foundational component of municipal and industrial fire protection systems, designed to provide high-flow water supply for initial fire suppression and fire truck water intake. Unlike indoor hydrants (smaller, wall-mounted), outdoor pillar hydrants are installed above-ground in open areas (roadsides, factory yards, commercial parks) for unobstructed access, even in large-scale emergency scenarios.
The BS750's robust design (cast iron body + brass valve) makes it resistant to outdoor weathering, physical impact, and water corrosion-critical for long-term reliability in exposed environments.
Key Features & Technical Specifications
Body (Cast Iron BS 1452): Made from British-standard BS 1452 cast iron, this material offers high impact resistance (to withstand vehicle collisions) and weather resistance (no rusting in rain/snow), ideal for year-round outdoor deployment.
Valve (Brass): Brass valves provide superior sealing performance (preventing water leakage in static conditions) and smooth operation (even after months of inactivity)-critical for rapid response during fires.
Bolts (Stainless Steel): Rust-proof stainless steel bolts secure the hydrant's flange connection, avoiding seizure (common with regular steel bolts) that would block maintenance or operation.
3. Technical Specifications (With Practical Context)
| Parameter | Details of SF750 | Practical Fire Scenario Interpretation |
|---|---|---|
| Inlet Connection | DN100 Flange (NASI/BS standards) | DN100 (4-inch) flange fits large-diameter fire pipelines, delivering up to 1500L/min flow (enough for 2+ fire hoses) |
| Outlet Options | 2.5" NST/BS336/Storz/Gost (2 outlets) | Multiple outlet standards adapt to fire equipment in different regions (e.g., Storz for European gear, NST for North America) |
| Working Pressure | 290 psi (20 bar) | 20 bar pressure supports a 50m+ water jet range-sufficient for initial suppression of small outdoor fires |
| Test Pressure | 435 psi (30 bar) | 30 bar pressure testing ensures the hydrant can withstand sudden water surges (e.g., fire truck pump startup) without leaking |
| Height | 800mm | 800mm height keeps outlets accessible (not buried by debris) while remaining stable in strong winds |
| Color | Red (customizable) | Red is the global standard for fire equipment-ensures high visibility in emergencies (even at night) |
Fire Safety Insights
1. Two Key Functions
Initial Fire Suppression: Trained personnel can connect a 2.5" fire hose directly to the SF750 to extinguish small outdoor fires (e.g., garbage bin blazes, vehicle leaks) before they spread.
Fire Truck Water Intake: For large fires, fire trucks connect to the hydrant to draw 1000+ L/min water-far more than on-board tanks (typically 500L), enabling sustained large-scale suppression.
2. Critical Placement Rules (Global Standards)
To ensure accessibility:
Hydrants must be placed ≤120m apart (so no area is more than 60m from a hydrant-within fire hose range).
They must be ≤2m from road curbs (fire trucks can park and connect quickly).
They must be ≥5m from building walls (avoiding damage from collapsing structures).
3. Why Regular Maintenance Matters
Outdoor hydrants are often neglected-here's the risk:
Clogged outlets (from dirt/insects) block water flow during emergencies.
Seized valves (from rust) prevent the hydrant from opening when needed.
Leaking bolts waste water and reduce pressure.
FAQ
Q1: What is the main function of this fire hydrant?
A: It is designed to provide a stable, pressure-regulated and high-flow water supply for firefighting in municipal and industrial fire protection systems.
Q2: How does the pressure-regulating function work?
A: The built-in pressure regulating mechanism automatically controls the outlet pressure within a safe range, protecting hoses and firefighting equipment from pressure fluctuations.
Q3: What materials are used for the hydrant body?
A: The hydrant body is typically manufactured from high-strength ductile iron with a corrosion-resistant surface coating for outdoor use.
