- This is a fire fighting tutorial video about "Pressure Sensing Lines Fire Pump for NFPA 20 Fire Pumps" in Urdu/Hindi language. These pressure sensing lines are used with a jockey pump, electric fire pump, and diesel fire pump. It is basic learning detailed information about Pressure Actuated Controller Pressure Sensing Lines as per NFPA 20 standard requirements. It is also important for Firefighting/MEP technical staff. Here sharing my experience and knowledge that will be helpful to learn & grow for Engineers & Technical staff. If you found anything which is inappropriate then convey it in the comments for my information and rectification in the future.

Informative 👍👍
Thank you
Very good and informative
Thanks
Bhut achi class sir🇮🇳🇮🇳
Thanks
Tanweer, always like your video. Please make videos on NFPA 25.
Ok noted and thanks for feedback
Hi.. i have doubt..
Why there is two check valves in sensing line .. for dampening purpose one check valve is enough , right?
It is as per NFPA requirements
Thanks for sharing and can you explain how to testing for fm200 and testing for fire pump?
InshaAllah I will
Hi sir,
How to zone high rise building to use multi stage pump?
Floor zones and height zones are different
how much distance should be maintained between check valve and 90 deg. elbow in sensing line? is there any requirement for this
Minimum distance should not less than 5 feet from check valve to check valve of sensing line is given in NFPA 20 but maximum limit is not provided therefore follow maximum distance as per site conditions.
Engr Tanver Pl show drg in the full screen
Ok noted
Bhai mujhe booster pump ka suction header aur discharge header change karna hai.. to mujhe pressure vessel ka line kholne se pehle kya procedure follow karna chahiye
Follow equipment manufacturer guidlines
Hi. Is this applicable if the system has an Alarm Check Valve?
Yes it is applicable
Both NRVs should be in direction from panel to pump discharge line or only one near to panel?
Only one near to panel
Engr Tanver Pl explain valves with zoomed schematic drg
Ok noted
Electric pump diesel pump both I'm talking.. band kaise hota hai automatic ya manually bnd krna parta hai.
Electric fire pump on & off automatically. Diesel fire pump on auto and off manually
On an external Fire Hydrant line, is there any minimum requirement to put pressure gauges? Like any specific distance, or on each fire hydrnt?
Pressure gauges shall be installed only in fire pump room. During testing of fire hydrants, pressure gauge arrangements will be arranged.
Aoa,
Hope you are doing well and fine.
Sir plz confirm that Pressure sensing line can be connected with horizontal split case pumps only as it comes with seperate control panels like for jockey we have separate control panel for electrical pump we have separate control panel like wise for standby pump.
What about end suction pumps on which single control panel provided with pump set EDJ. ?
Kindly watch video, all detail is explained. Sensing line provide separate for each pump
Ok sir thanks
Sir deisel pump start to automatically hota hai... Sir isko off manually kiya jata hh ya off bhi automatic hota hai please answer ...
Off manually, almost
Can we use brass pipe for sensing line?
As per NFPA requirement is copper tubes and stainless steel tubes. You are following standard requirements or not, now it's up to you.
Pls provide English subtitles 😊
I will try to write subtitles
I have 1000gpm electrical and Diesel pump but running time 400gpm getting not going above
How did you know that flow is 400gpm and not flowing more?
@@TanweerAhmed showing the gpm meter
It will be physically checked either problem in pump, flow meter, installed pipes or somewhere else
Are you CFPS ?
No
@@TanweerAhmed You must try it. You have a very good knowledge.
What is the requirement?
@@TanweerAhmed Ye bhi sahi he. Good, if we have some certificates as a Consultant
👍
