Since the 1880s, A C Fire Pump has been a leader in fire pump manufacturing. Today, we design and custom-build modern fire pump systems capable of handling almost any fire protection job in commercial buildings, factories, institutions, and tall buildings.
A C Fire Pump is a member of the National Fire Sprinkler Association (NFSA) and the American Fire Sprinkler Association (AFSA). NFSA supports education, engineering, and public fire protection plans. AFSA promotes proper automatic sprinkler system installation, advanced technology, and smart fire protection practices.
A Shared History of Excellence
One of the first motorized fire trucks in the late 1800s used an A C fire pump. For over a century, A C Fire Pump Systems has remained a top provider, designing and custom-building fire protection pump systems and pump houses for all requirements. Notably, we supplied fire pump packages for NASA’s Kennedy Space Center launch pads 39A/39B, including four 12×8×22 9100 series horizontal split case pumps powered by 1,065 hp diesel engines, each moving 3,500 gallons per minute at 250 psi.
NFSA activities include engineering, training, education, and public fire protection programs designed to create widespread acceptance of competently installed automatic fire sprinkler systems in both new and existing construction, from homes to high-rise buildings.
AFSA supports the merit shop automatic fire sprinkler contractor through educational and training programs that maintain the quality and effectiveness of automatic fire sprinklers. AFSA encourages an expanded role for automatic fire sprinklers in protecting lives and property, disseminates information on labor, technology, and business, and provides programs to enhance business practices for the merit shop contractor.

Benefits of Code-Compliant Fire Pump Systems
- NFPA 20 sets strict rules for pump operation, installation, certification, and pump room design
- Proper systems reduce risk, ensure compliance with insurance and legal requirements, and protect life and property
- Pre-packaged pump houses simplify installation, minimize site work, reduce errors, and speed up commissioning
Key Design & Installation Considerations
- Pump room location: NFPA 20 requires specific access, fire-rated walls, airflow, heating (for cold areas), and dedicated pump use
- Pump selection and sizing: Flow and pressure must meet design requirements; incorrect suction or placement can cause failure
- Certification and listing: Only UL Listed or FM Approved fire pumps are acceptable; standard water pumps are not suitable
- Installation package: Pre-piped and pre-wired units reduce errors, ensure code compliance, and simplify installation
- Testing and maintenance: Regular inspections, no-flow and full-flow tests, record keeping, and adherence to NFPA 25 ensure reliability
Common Product Features
- Horizontal split case, vertical turbine, in-line, and end suction fire pumps available with electric or diesel drivers
- Pre-packaged systems include driver, controller, test header, suction/discharge valves, flow meter, and base frame
- Custom pump houses feature control panels, engine room airflow, emergency lighting, and fire-rated construction
- Optional components include fuel tanks (for diesel), jockey pumps, relief valves, meters, and additional code-required accessories

Frequently Asked Questions
A fire pump system supplies the right water pressure and flow to sprinklers, hydrants, and hose reels during a fire. Without it, sprinklers may fail to control a fire, making fire pumps essential for safety in most commercial, industrial, and tall buildings.
All systems comply with NFPA 20, and components like pumps, controllers, and engines are UL Listed and FM Approved, ensuring full compliance with international fire safety and insurance standards.
Selection depends on building type, water requirements, sprinkler design, and local codes. Our engineers perform detailed flow calculations to determine the correct pump type (horizontal split case, vertical turbine, end suction, or in-line) and ensure reliable performance.
Factory-made packages simplify installation, reduce site errors, and ensure all components—valves, controllers, wiring—are pre-tested and compliant with NFPA standards, enabling faster setup, reliability, and safety.
A-C Fire Pump Systems and Professional Fire Protection
A Shared Tradition of Excellence One of the first fire trucks built in the late 1800’s was
equipped with an A-C Fire Pump. For over 100 years, A-C Fire Pump Systems has been on the
forefront in developing, designing and custom-building a wide range of fire pump systems
including prefabricated packages and house units that meet every fire protection need. A-C Fire
Pump is not only rich in history, but on the cutting edge of new technology as demonstrated with
our contribution to the fire protection systems for launch pads 39A and 39B for NASA at the
Kennedy Space Center. A-C Fire Pump Systems furnished a package of four 12x8x22 9100 series
horizontal splitcase pumps driven by huge 1065 horsepower diesel engines including
state-of-the-art control systems. Each pump is rated at 3,500 gallons per minute at 250 psi
pressure. We will continue to be the leader in the fire protection industry providing both
