Fire Pump Design
When the municipal water supply cannot deliver the pressure and flow a sprinkler or standpipe system demands, a fire pump bridges the gap. DGA Consulting designs fire pump installations per NFPA 20 for commercial, industrial, and institutional facilities, from water supply analysis through acceptance testing support.
What’s included
What fire pump design includes
DGA Consulting designs fire pump installations for commercial, industrial, and institutional facilities. The firm’s engineers handle everything from the initial water supply analysis through pump selection, room layout, and acceptance testing support.
Pump sizing and selection
Rated flow, rated pressure, and driver type (electric or diesel) matched to system demand and the available water supply.
NFPA 20 compliance
Suction and discharge arrangements, relief valves, test headers, and controller requirements designed per NFPA 20.
Fire pump room layout
Equipment arrangement with required clearances, drainage, and ventilation for the pump, driver, and controller.
Jockey pump design
Pressure maintenance pump sizing that keeps the system pressurized without cycling the main fire pump.
Acceptance testing support
Test criteria defined per NFPA 20 with field support through the acceptance test and commissioning.
When it applies
When fire pump design applies
When you need it
- Tall buildings where elevation head exceeds the available municipal water pressure.
- Large warehouses and storage facilities with high sprinkler flow demand.
- Sites served by weak or limited municipal water supplies.
- Facilities with an existing pump needing a performance and NFPA 20 compliance evaluation.
Process
The design process
01
Water supply analysis
Flow test data analyzed and system demand calculated to determine the shortfall, if any.
02
Pump selection
Rated capacity and driver type selected for the demand, the supply, and reliability requirements.
03
Design
Room layout, piping arrangement, and controls designed per NFPA 20.
04
Testing
Acceptance test criteria defined and field support provided through commissioning.
