Many Thanks Vasudevan,

Can you share the design of the stand you are using to hold the rain gun.

Thanks,

Hi Vasudevan,

Do you know if raingun works when the bore pumps intermittently? Did you get into that situation ever?

Dear Mr Chandra
As I was out of station I did not answer you question. I have two open wells with submersible pumps. No problem with that. If the bore pump is capable of discharging at least 2kg per square cm, the rain gun can work.

hi,

I have 3HP pump bore pump and my output is 200L in 2.5min means  80L per minute.

How should I calculate  pressure KGS?

In this article, its mentioned to have minimum 2.5 KGS pressure to operate raingun and repeatedly mentioed min 5HP motor.

I am wondering if I can use the rain gun mentioned in this article.

I have 2 acre land with flood based irrigation. Currently its labour intensive and insuffucient water

I am thinking whether I should use sprinkler/micro sprinkler/rain gun?

regards,
rajsekhar

Dear Mr Rajashekar
I too not measured the pressure, but I am sure the minimum 2.5 kg per square pressure is available in 5HP pump with 2inch dia delivery pipe. Best is 7HP pump. It is not achievable in 3HP pump. If you have borewell, then the pump shall be multistage type.

Dear Vasudevan,

Thanks for sharing this info. I think it would be most useful if you can provide more details on how you installed it, the field coverage, cost etc. Some pictures will be great too.

Dear Mr RDP
I am sorry for my delayed mail. Hose pipes can not withstand such a high pressure (here it is 2kg/sqcm minimum).
HDPE pipes are the best .

Hi,

Can someone let me know which among following Rain Guns to purchase and why?
1) Italian RainGun : Skipper/Hidra by Vedanta Agro
2) Varsh by Severals
3) 140 Plus by Jain Irrigation
4) Penguin by Thumba Agro

I need a Rain Gun to run on lower pressure as I intend to run it on a Diesel Engine.

Thanks
Nilesh

Dear Shesha

HDPE or PVC the water carrier should be rated for pressure enough to withstand the expected flow of water at a high velocity.

So the selection would be based on;

A) Volume of the flow
B) Pressure rating of the rainguns nozzle

There are great quality brass rain gun mfrs around. Discussing in detail would clear all your doubts.
