If you own or manage a commercial property in the Florida Keys, your fire protection system is only as effective as its fire pump. A fire pump ensures adequate water pressure and flow to your fire sprinkler or standpipe system — especially in low-pressure areas or large buildings.

At Gary’s Plumbing and Fire, we’ve been helping local businesses and property owners select, install, and maintain fire pumps for over 30 years. This guide will help you understand what to consider when choosing the right fire pump for your commercial property in Key West or the surrounding Keys.

What Is a Fire Pump?

A fire pump is a critical component of your building’s fire protection system. It increases water pressure from your water supply source (city mains, tanks, or wells) to meet the required pressure for sprinkler or standpipe systems during a fire emergency.

Fire pumps are required when:

• Water supply pressure is inadequate for fire protection needs
• The building is multiple stories high or has long pipe runs
• The sprinkler system requires higher demand pressure
• The property is using a water storage tank or private well

Types of Fire Pumps for Commercial Use

There are several types of fire pumps commonly used in commercial fire protection systems:

Horizontal Split-Case Pumps

• Most common for commercial buildings
• High flow capacity and durability
• Requires a water source with positive pressure
• Easy to service

Vertical Turbine Pumps

• Ideal for deep wells or underground water tanks
• Common in areas with limited municipal water supply
• Suction is drawn from below-grade sources

Vertical In-Line Pumps

• Compact and great for buildings with limited space
• Installed directly in line with piping
• Easy to maintain but slightly lower flow rate

End Suction Pumps

• Good for smaller commercial applications
• More compact and cost-effective
• Slightly lower pressure output

Key Factors to Consider When Choosing a Fire Pump

✅ Water Supply

Are you using city water, a storage tank, or a well? Your pump must match the available source and ensure sufficient suction and delivery.

✅ Building Size & Occupancy

High-rise condos, hotels, marinas, and warehouses all have different flow and pressure demands. Larger properties often require split-case or turbine pumps.

✅ Flow Rate & Pressure

Calculated in GPM (gallons per minute) and PSI, your local fire code or fire engineer will determine the minimum required specs. Choosing the wrong size pump could result in code violations or system failure.

✅ Power Source

Fire pumps can be powered by diesel engines, electric motors, or steam turbines. In hurricane-prone areas like the Keys, diesel-powered pumps may be required to ensure operation during outages.

✅ NFPA Compliance

All systems must be designed in accordance with NFPA 20 and installed to meet Florida Building and Fire Codes. You’ll also need regular NFPA 25 inspections post-installation.
