How to Ensure Your Fire Pump Meets NFPA 20 Standards

A fire pump is a critical component of a fire sprinkler system. It is designed to increase water pressure and flow for firefighting. It works by drawing water from a reliable source and boosting its pressure to ensure effective water distribution through sprinklers or hoses.

Power surges or electrical disturbances can impact the operation of electric fire pumps. Proper surge protection measures, such as surge suppressors and lightning protection, should be in place to safeguard the electrical components of the fire pump system.

Testing Requirements:
Weekly Run Tests: Diesel pumps should be tested for 30 minutes weekly, and electric pumps should run for 10 minutes.
Annual Flow Tests: Measure pump performance at 100%, 150%, and churn conditions to verify proper operation.
Check Suction & Discharge Pressure: Ensure the pump meets its rated pressure at all test points.
Evaluate System Response Time: Confirm that the pump starts automatically when required.

Fire pumps work by drawing water from a water source (such as a storage tank or a dedicated water supply) and then increasing the pressure to deliver water through the fire sprinkler system or hoses. They are typically powered by electric motors or diesel engines.
