Gallonage Fire Nozzle

A Gallonage Fire Nozzle is a type of firefighting nozzle specifically designed to control and regulate the flow of water (or firefighting foam solution) measured in gallons per minute (GPM). It is one of the most commonly used nozzles in municipal and industrial firefighting because it offers firefighters flexibility, efficiency, and control during operations.

1. Definition

A gallonage nozzle (also called a selectable gallonage nozzle or fixed gallonage nozzle) allows the operator to choose or maintain a predetermined water flow rate.

Flow rate is expressed in GPM (gallons per minute) or LPM (liters per minute).

2. Types of Gallonage Nozzles

Fixed Gallonage Nozzle

Provides a constant flow rate at a given nozzle pressure (usually 100 psi).

Simple, durable, and easy to operate.

Commonly available in sizes such as 60 GPM, 95 GPM, 125 GPM, 250 GPM, etc.

Selectable Gallonage Nozzle

Equipped with a rotating ring or selector switch to choose different flow rates (e.g., 30/60/95/125 GPM).

Useful when water supply is limited, or when different fire conditions require different flows.

Provides more operational flexibility for firefighters.

3. Features

Stream Patterns: Adjustable from straight stream to wide fog, allowing cooling, protection, or reach.

Durability: Usually made of hard anodized aluminum or brass with rubber bumper protection.

Ergonomics: Many models come with pistol grips and shut-off handles for ease of use.

Compatibility: Can connect to different hose sizes (1.5", 2.5", etc.).

4. Applications

Municipal Firefighting: Flexible flows for residential or commercial fire suppression.

Industrial Facilities: Used where different flow rates are needed for hazards such as chemical plants, oil refineries, or warehouses.

Wildland/Forestry Firefighting: Lower gallonage settings conserve water while still providing effective fire streams.

5. Advantages

Flow Control: Ability to match water supply availability with fire conditions.

Operational Flexibility: Firefighters can switch between different flow rates instantly.

Efficiency: Helps conserve water during small fires while delivering high flow for larger incidents.
