Water pump for fire hose 2

[Stones123]

I am trying to speck a water pump that can be used as a fire extinguisher.

Have a water basin right next to my house at street level. Depth of this basin is ~ 1 meter.
From the bottom of this pond to the top of the house is approx 15 meters or 12 meters to terrain from where one will stand with hose.

I have searched several models and brands, but when asking for technical help (besides whats written on the crate - Hp, Motor size, liters / min.) no one is able to answer.

Hope someone her can assist.

Cheers

Not the least important question BTW. Fire often knocks out the power first, if the power did not start the fire to begin with and purposely is not cut off then, or later.

Biggest issue really is that people buy them, maybe fit them and run them once or twice for fun / look at me, then do nothing for 5 years until they suddenly need it when it won't start of the fuel has either evaporated or gone off...

That's before they wonder why it won't flow any thing when the inlet line is full of air or the inlet has become clogged with dirt /fish / rocks or just perished in the sun..... Or has been stored in the shed which is now burning.

If he has a basin with water is there a reason that a submersible wouldn't be a good idea. They can be outfitted with some type of suction screen to limit debris going in(whether it starves the pump eventually is something he should test out)

Also agree that main electric supply should not be relied upon for this type of equipment although if he has a whole house generator, that could be considered if the generator is sufficiently far away from the house.

A submersible, especially if it sits inside a small bucket or on top of a few paving slabs plus a petrol powered generator is probably the best scenario as you could test it on mains power regularly, use the generator for other things and be good to go when the flames arrive.

The submersible I have looked at are not big/strong enough.
Looking at a gas driven one such as the Hyundai HY50. Unfortunately they don't write the (max) water pressure.

Says TDH of 32m.

So assuming a 2m lift into the pump that's 30m output, 3 bar, 45 psi. Bit low for firefighting.

Also 500 l/min - this is as the article says more of a water moving pump than a fire fighting one.

At least this one does say it is self priming, though suspect you still need to fill the impellor casing with water.
