If you come across a diesel fire pump and you happen to be doing a weekly, annual, or general operation test, please make a vid like this, I'm currently entering fire protection field and this is excellent info. I love learning from different people, places.
Raul Martinez not much difference. For diesel fire pumps typically they are in an enclosed outhouse or part of building. But they will have air louvers that you have to make sure that those operate close and open. Also that the diesel fuel tank is no less than two thirds full. Aswell testing the pump by manual crank on the engine controller or automatic means from dropping pressure on the sensing line on the electronic controller. Typically a .5” line. But the test churn time of diesel pumps are 30min. Not all pumps will have a auto off timer from 30min countdown but manual means [stop]Then opening the isolation valve to any risers or system feed. Open up so the jockey or sensing line can establish equalizing pressure then turn fire pump back on and it shouldn’t crank over. Should be in normal operating condition.
Nice video. When testing fire pumps that have a flow meters remember to check previous reports. NFPA25 states that fire pumps with a flow meters have to be tested by flowing water through hose streams every 3yrs.
A lot of information in 7:00 minutes. The fact that you yourself have to think before articulate what are you trying to convey, tells me that it can be confusing in learning all of this stuff about water pressure and water flowing directions. You did a great job in explaining the procedure. But I wonder if your audience, including me, was able to grasp any "how to" of this stuff. Nice presentation.
I have a doubt on the requirements. If we run at no-flow (shut-off condition), is it not detrimental to the pump? NFPA says 30mins for Diesel Engine driven pumps and 10mins for electric pumps.
Forgot to mention you’re supposed to do an angular/parallel alignment test on the coupling. If the pump alignment is not within manufacture specs it can reduce the longevity of the fire pump. Need to grease the bearings as well and the net pressure can be within 95% of rated pressure.
hi there, judging from the video, it looks like there's only a single pumpset for this fire protection service? do you guys practice the 1 duty 1 standby pumpset philosophy or is that not a requirement in NFPA?
Cna you explain the 1 duty 1 standby pumpset philosphy? I have never heard of this before and generally want to learn something new. It sounds interesting. THank you.
@@henriettafm8504 hi there, this tradition of having one identical pump as a standby came from British Fire Engineering practices that's been passed on for many years. Most common argument is that the primary electrical pump may lose power or something else may prevent it from starting in the event of a fire, and the back up standby pump , which is commonly diesel driven, will take over the primary pump during such events. For as to why this is not common in America, this forum has some solid answers www.meyerfire.com/daily/why-are-standby-fire-pumps-not-required
I do familiar with 1 set of fire pump consist of a jockey, an electric and a diesel fire pump rather than only 1 fire pump only... however i still curious by how to increase the flowrate into 150%, by increasing the opening? By increasing the rpm?
@@sanosagara4507 During your pump testing, you adjust the control valve to restrict the flow going into the flowmeter to get your exact duty point. At 150% of duty flow, all you do is open the control valve more to have a higher flow reading at the expense of lower pressure reading. your RPM for both motor and diesel is always fixed.
@@ann0ynim0us ok, i get it kind Sir... btw for no flow (churn), is it the control valve is totaly closed ? I have always been told it could damage the pump if the pump is running and the valve is closed

Excellent description Thank you
thanks very much Firend, hugs from Colombia!!
Are you supposed to subtract the city pressure from the numbers to make sure it’s putting out the right gpms

Havent done a pump test in 3 years. Great refesher

Good vid. Is there one where you involve the test header?

very good video
nice working
like it
keep it up

why is it negative suction?
It's not supposed to be negative
