scope:

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

FM 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 Approval criteria for vertical shaft, turbine 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.

FM 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.
