How to Select a Pump Model
- Determine sprinkler design flow according to hazard classification and protected area.
- Calculate required discharge pressure based on the highest sprinkler elevation and residual pressure.
- Verify system pressure losses across piping, valves, and alarm check assemblies.
- Select motor power based on rated duty point and starting requirements.
- Confirm compliance with local fire codes, electrical standards, and backup power requirements.
Engineering Notes
- The equipment shall be installed downstream of the fire water storage source or municipal fire supply.
- Automatic start shall be triggered by sprinkler pressure switch or fire alarm control signal.
- A dedicated test line is recommended for periodic flow verification and commissioning.
