scope:

This standard encompasses the design and performance requirements for rotary gear type, positive displacement fire pumps for use in fire protection systems. Approval is limited to such pumps which have a rated pressure of a minimum of 40 psi (2.75 bar). In cases where metric size pumps are to be examined for Approval, test criteria comparable to the United States equivalent size shall be used.

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 FM Approvals criteria for rotary gear type, positive displacement fire pumps that supply water and/or foam concentrates to water mist or foam fire protection systems. These pumps must be available for many years to operate reliably at rated capacities and pressures during emergency fire incidents, despite being idle for extended periods.

FM Approvals 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.
