Scope:

Most in-line pumps are designed to have the electric motor shaft directly attached to the pump shaft rather than a separate pump shaft. With this in mind, an in-line the pump is always provided with an electric motor. As indicated in 9.5.1.1 of NFPA 20-2022, electric motors shall be specifically listed for fire pump service. Also, sections 4.7.6 and 9.5.2 of NFPA 20-2022 require the electric motor have a horsepower (with any adjustment for service factor) equal to or greater than the horsepower required to drive the pump at rated speed under maximum pump load. The new 9.6 proposes to require that these types of in-line pumps comply with these provisions of NPFA 20.
