HEAVY DUTY RESIDENTIAL FIRE PUMP (HDR) 13D

For some projects, a full listed NFPA 20 style fire pump system is simply overkill. The HDR systems are designed for occasions when the long lead time and greater expense of a listed system may be a major hardship. These packages use carefully selected industrial grade pumps and robust residential (NFPA13D) controllers with complete alarm features. They include listed monitored valves and NFPA20 style sense lines. Each system is flow, pressure, and electrically tested prior to shipping. Many fire marshals or AHJs will allow these systems but this will vary by locale or individual. As such, we ask that you submit the system to your AHJ for approval prior to ordering.
