D Systems residential fire pumps have been preferred by contractors and trusted by home owners for over 30 years.

                                       NFPA 13R

~ NFPA 13R code allows “ a connection to a water work system with or without a pump, as required. Fire pump shall be installed in accordance with NFPA 20. NFPA 20 says, centrifugal fire pumps and controllers shall be listed for fire protection service. This should not be confused with an ul listing for the motor. D System components including the controller comply with NFPA 13R, w/ the exception of the pump. The pump meets all the performance criteria, and the motor is UL Listed, however the pump is not listed per NFPA 20. A listed NFPA 20 pump would resemble a large commercial type pump and cost many times our complete system. For  13R projects with a strict budget and lower flows all options need be considered.  *When the D System is being used in a NFPA 13R application, the “Authority Having Jurisdiction “ is to be aware, and have accepted the pump. Contractors and owners alike want the best product for the best price. No one wants a problem after the installation.
