1000 Gpm Fire Pump Flow Test 134 5 Psi Flow Hi friends kaise ho aap sab, is video me mai fire pump flow testing system ke bare me bataya hu mujhe umid hai ap log ko mera video achha lga hoga aagr koi v. While a reduction in output is usually a matter of concern, a.8.3.7.1 of nfpa 25 warns that it should be evaluated in light of meeting the pump’s rated characteristics. to pass an annual flow test, fire pump performance at each flow and pressure point must not be less than 95 percent of the nameplate data.
Fire Pump Flow Test Reports Code Red Consultants An annual pump test is actually a series of timed tests as follows: 5 minute dry vacuum test, timed primer test, 20 minute test at rated capacity and 150 psi, 5 minute "spurt" (overload) test at rated capacity and 165 psi, (not required by iso but recommended by nfpa) 10 minute test at 70 percent capacity and 200 psi,. Use our fire pump test hose calculator to estimate how many hoses will be required to test a particular pump. simply enter the fire pump and test information below. the results are based on the maximum flow required and friction loss to the flow device. there is always the possibility of job factors or variables we did not consider. Each pump section addresses the three primary tests of 100%, 70% and 50% capacity. if you choose to do the optional overload or "spurt" test you can use the same setup as used for the 100% capacity test. you should resist the temptation to reduce the length of the hose lays. some friction loss is needed to maintain the pressure differential. 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.

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. As an example, for a pump with a rated capacity of 2000 gpm, test points are 0 gpm, 2000 gpm and 3000 gpm (150% of rated capacity). if 3000 gpm can not be achieved during the flow test, then the maximum flow rate should be targeted, and the maximum flow rate along with corresponding suction and discharge pressures should be recorded. 875 gpm @ 200 psi = (3) 100' lines. 625 gpm @ 250 psi = (2) 100' lines. the hoselines for the 200 and 250 psi test are unchanged from the chart. basically, for the 150 psi test, he said to drop down to 50' on one line to see if that will give the desired flow at the correct pump pressure. he said if it doesn't, drop an additional line down to 50'.
