Fire fighting_lesson 3 | Fire pump system description, sizing and testing

Fire pumps related to sprinkler systems usually comes as a set of three pumps: Jockey pumps, electric or main pump and diesel pump.
You will learn in this video how to test the fire pumps and how to define the cut on and cut off pressures of fire pumps.

Beautiful, I'm a BIM Modeler at an engineering company, very helpful!

[@asemtantawy5779]

That's great
Its too clear showing video
Thanks alot

[@hasifp73]

Nice explanation

[@kingking-yb5xc]

Amazing video, thank you for sharing this with us!

[@AMJEngineering]

You'r welcome

[@avcomth]

In my country, municipal building codes govern that the entire pump system should only be fed from a dedicated reservoir connected to the public running water and regulated by float valve.

[@AMJEngineering]

thanks for info

[@williamwatkins4242]

You should test it also whilst the 3 pumps are in auto mode to check the correct sequence of operation when there is more demand.

[@AMJEngineering]

yes you are right

[@arnelada6216]

You should test it also whilst the 3 pumps are in auto mode to check the correct sequence of operation when there is more demand. Assuming 3 pumps are in auto mode, does the Jockey Pump operate together w/ the Main Fire Pump when the MFP reach its cut-in pressure? Or there is an interlock between the 2 pumps (JP & MFP)? How about the Diesel FP, does it operate w/ the Main FP when it reach its cut-in pressure?

Sorry im just learning.. What is the difference between the diesel and the main pump and their respective role?

[@AMJEngineering]

Both electric and diesel fire pumps provide fire sprinklers throughout a facility with adequate water supply during a fire.
diesel engines are often used when the electrical supply to the property is interrupted or if the electric pump capacity is insufficient to kill the fire (i.e. when the pressure in the system drops below the diesel pump setting, meaning more and more of sprinkler heads are broken due to more spread area of fire)

[@arnelada6216]

How about if there is more demand while the Electric Fire Pump is running and reach the Diesel Fire Pump cut in pressure? Does Diesel Fire Pump assist the Electric Fire Pump? Or will it just operate during power failure only?

[@arnelada6216]

Hmm

[@makemeyouprick]

what is the brand of that fire pump set

[@AMJEngineering]

Sorry, Iam not sure

[@borneopride204]

Hey, bud i would like to know if the diesel pump start automatically when no power supply available

[@AMJEngineering]

Yes
If main elec didn’t get online, diesel get online

[@mubarakhassan4533]

great, can u please share

[@Changeclimates101]

Electric pump and jokey is okay proper maintain pressure but no auto off....?

[@CHLEOMENTETV]

Is it a vioalation when you let the firepumps set to Manual and not in Auto?

[@AMJEngineering]

It should be in auto, otherwise, it may not do its job in case of fire.

[@ashwinsingh2307]

Hi
Can i know, why the fire diesel engine gets overheat and seize

[@AMJEngineering]

It depends, could be not cooled properly. Check the radiator and fan. Also, make sure the condition of the engine parts are good before running again.
