scope:

This standard encompasses the design and performance requirements for in-line type, centrifugal fire pumps for use in fire protection systems. Approval is limited to single stage, in-line type, centrifugal fire pumps that have a minimum rated discharge pressure of at least 40 psi (275 kPa). In cases where metric sized in-line type, centrifugal fire pumps are to be examined for Approval, test criteria comparable to the United States equivalent size shall be used.

Requirements for other types of centrifugal fire pumps are detailed in the following Approval standards:

Class Centrifugal Fire Pump Type

1311 Split-Case Type, (Axial or Radial)

1312 Vertical Shaft Turbine Type

1319 Horizontal, End-Suction Type

1370 Vertical Turbine Barrel Type

Requirements for other major components in the pump package are detailed in the following Approval Standards:

Class Equipment

1046 Fire Pump Flowmeter Systems

1321/1323 Controllers for Electric Motor Driven and Diesel Engine Driven Fire Pumps

1333 Diesel Engine Fire Pump Drivers

1359 Trim Water Pressure Relief Valves

2311 Pressure Gauges for Fire Protection Systems

Approval standards are intended to verify that the product described will meet stated conditions of performance, safety, and quality useful to the ends of property conservation.

Purpose

This standard states Approval criteria for in-line, single stage type centrifugal fire pumps which supply water to fire protection systems. These pumps must have an extended service life, throughout which they must be capable of operating reliably at rated capacities and pressures during emergency fire incidents, despite being idle for extended periods.

Approval criteria may include, but are not limited to, performance requirements, marking requirements, examination of manufacturing facility(ies), audit of quality assurance procedures, and a follow-up program.
