Get Dod Pumper Practical Form

To pass the flow test, a fire pump must be capable of supplying the full system demand, which is provided by the property owner. The performance at each flow and pressure point also must not be less than 95 percent of the pump's nameplate data or the pump's original unadjusted field test curve.

Run the pump for 20 minutes at 100% of rated capacity, with a net pump pressure of 150 pounds per square inch (psi). The NFPA requires this test for pumps rated for over 750 gpm. Immediately after the 20-minute test, run the pump for 5 minutes, at its rated capacity, at 165 psi.

During the acceptance test, NFPA 20 requires several flow demands to be tested: no-flow (also called churn or shut-off), 100 percent and 150 percent of the rated capacity. Additional points may be tested, but not less than 50 percent of the flow rate is recommended.

NFPA 20 protects life and property by providing requirements for the selection and installation of pumps to ensure that systems will work as intended to deliver adequate and reliable water supplies in a fire emergency.

Electric pumps must be run for a minimum of 10 minutes while diesel pumps must be run for a minimum of 30 minutes. Qualified personnel must be in attendance whenever the pump is in operation unless automated inspection and testing is performed in ance with the requirements of NFPA 25.

ing to the NFPA 1901, Standard for Automotive Fire Apparatus, the vehicle must be equipped with a pump rated at a minimum of 1000 gpm and a water tank of at least 300 gallons. 110- or 220-volt AC current.
