  • Description

    Revised to clarify an array of requirements and applications, the 2022 edition of NFPA 20, Standard for the Installation of Stationary Pumps for Fire Protection, further establishes best practices to help ensure state-of-the-art fire protection.

    Industry-trusted NFPA 20, Standard for the Installati on of Stationary Pumps for Fire Protection, offers the latest provisions to help ensure fire pump readiness and reliability. This standard offers comprehensive requirements for fire pumps, limited service controllers, and pumps in series. Designers, engineers, contractors, and installers can look to this expanded source for the latest coverage of today's technologies and up-to-date requirements for fire pump design, electrical and mechanical construction, acceptance testing, and operation.

    New requirements added in the 2022 edition address a number of recent advancements in the field of stationary pumps for fire protection.

    This edition includes first-time or expanded coverage of topics such as:

    • Separate requirements for vertical and horizontal shaft centrifugal pumps
    • Automated inspection listing requirements
    • Minimum water level in storage tanks
    • Clarification of vertical fire protection zones
    • Operation and installation instructions
    • Mechanical seals requirements
    • Maximum time to achieve design pressure

    Other aspects of this newest edition can help you avoid errors and misinterpretations.

    The 2022 edition of NFPA 20, Standard for the Installation of Stationary Pumps for Fire Protection, clarifies and enhances the requirements for numerous subjects, including pump currents, overcurrent protection devices, and transfer switch installation.

    In addition, the positive pump displacement requirements have been reorganized and new performance requirements have been added. The new edition also recognizes an improvement in fuel consumption by diesel engines and changes to fuel supply tank capacity. Another topic of some importance is test header pipe size, including pipe size requirements that are based on the number of fittings used.

    Fire pumps have greatly increased in number and function since their early days as backups to sprinklers, standpipes, and hydrants.

    Fire protection now requires larger pumps, higher pressure, and more varied units for a wide range of systems to help better protect lives and property. Some fire pumps now serve as the major or only water supply in an area. These recent advancements in the field can help engineers, designers, contractors, and installers work more effectively.

    For the requirements you need to know about fire protection with stationary fire pumps, update to the new NFPA 20, Standard for the Installation of Stationary Pumps for Fire Protection, today. (Print, Approx.198 pp., 2022)

  • How the NFPA Handbooks Differ from Codes and Standards

    THE NFPA HANDBOOKS DIFFER FROM CODES AND STANDARDS

    Ever wonder what the difference is between an NFPA® handbook and a code or standard? We’re glad you asked.

    NFPA codes and standards both provide requirements for achieving outcomes. Handbooks take a deeper dive, providing the full text of a code or standard as well as expert commentary and features such as graphics, decision trees, testing procedures, case studies, sample forms and checklists, and other helpful aids to give a better understanding of the reasoning behind the requirements and how to apply them.

    JUST REMEMBER:

    • A code or standard is a framework—a set of rules to follow with a goal to achieve a certain result
    • A handbook is a connector—linking requirements to application by helping you understand the reasoning behind a code or standard

    The simplest way to think about it is that codes and standards list the technical requirements while handbooks explain those requirements to clarify how to apply them.
