Scope:

1.1 These requirements cover stationary centrifugal fire pumps intended for use in water-supply systems for fire-protection service.1.2 The pumps covered by these requirements are intended for installation and use in accordance with the Standard for the Installation of Stationary Pumps for Fire Protection, NFPA 20.

Project need:

The proposed revisions to the nameplate requirements are being updated to allow for the use of aluminum and UL 969 Marking and Labeling Systems. Aluminum, while not meeting the definition of corrosion resistant within UL448, is considered a suitable alternative for a nameplate application. In addition to this, the proposed alternative of pressure sensitive labels are permitted for other fire protection products. Brackets are commonly used for pumps that have larger nameplates where attachment to the pump casing is not feasible. Another proposed change seeks to clarify wording specifically to bowl wear rings so that a non-metallic material can be used (e.g., specialised thermoplastic). Bowl wear rings/bearings are put under the same immergence/conditions and bowl bearings already have wording supporting non-metallic materials under clause 16.1.
