                                                 FIRE PUMP FLOW TEST REPORTS Fire pumps are an essential component of many water-based fire protection systems. They are used in instances where a building’s demand pressure exceeds the pressure that can be provided by the water supply. NFPA 25 describes the different testing methods that can be utilized for this test. Three separate scenarios occur during the annual flow test:=No-flow (Churn): This represents the pump at minimum flow which should not exceed 140% of the rated pressure =100% rated flow: This represents the pump’s rated flow at its rated pressure=150% rated flow: This represents a pump’s flow at 65% of the rated pressure These flows are achieved by discharging specific amounts of water through the fire pump test header using approved testing devices that measure the flow and pressure coming from each t...
