Fire Pump Testing Flow Chart

The fire pump flow test is required by nfpa 25 to be conducted once a year in order to measure the pump s flow and pressure.

Fire pump testing flow chart. Solid bore nozzle flow chart. Fpt stores all of your fire pump information calculates flow rates and graphs pump test curves. It can also uncover any problems with the pump s water supply such as closed valves or obstructions. Fire flows can cause damage to surroundings e g vehicles pedestrians landscapes and can cause flooding in the vicinity or remote to the site.

This application has auto adjusting axis divisions and automatically calculates avaliable flow or pressure at a single point. The following information provides an overview of the requirements. 4 5 care should be taken to avoid causing nuisance during and after the tests. The hoses are run to a safe location where the flow of water will cause no damage.

Quickly determine you water supply capabilities with our on line application for graphing fire hydrant flow test information on a logritmic graph n 1 85. Fire pump tester software fpt allows fire protection contractors fire protection engineers and building managers to collect fire pump test data in a professional and comprehensive format. All nozzle pressures are pitot gauge readings not pump pressure gauge readings. It meets the nfpa 1901 class a pump rating test and iso requirements for annual pump or service test.

The annual fire pump flow test is a full test of a pump s capabilities and is arguably the most critical test. To help ensure the fire or booster pump is working there needs to be periodic inspection maintenance and testing of the pump.
