Comprehensive requirements for the selection and installation of stationary fire pumps.

The 2025 edition of the industry-trusted NFPA 20, Standard for the Installation of Stationary Pumps for Fire Protection, offers the latest provisions to help ensure fire pump readiness and reliability. This standard offers the requirements for the installation of stationary fire pumps used to provide water supply for fire protection.

Designers, engineers, contractors, and installers can look to this standard for the latest  up-to-date requirements for fire pump design, electrical and mechanical construction, acceptance testing, operation, and more.

The 2025 edition includes several important revisions, including:

• Standardization of the term jockey pump throughout the standard
• Clarifications on the arrangements for fire pump controllers and automatic transfer switches
• Expanded requirements for automatic testing and automatic remote testing for electric-driven fire pumps
• New requirements for automatic testing and remote automatic testing on diesel-driven fire pumps
• New requirement on alternate source of power for electrically powered diesel pump room components
• Clarifications on the distinctions between circulation relief valves and main relief valves, the sprinkler protection for fire pumps, the isolation for redundant variable speed pumps, and the overcurrent protection for electric-driven fire pumps.
