Possible coolant pump?

Just came across this:

Made me :think: It would obviously have to be able to push pretty hard to get water up a bore at any useful speed. What do you fellas reckon?
Be any use as a coolant water pump?

I can't see why it would not work, but it is over kill. 2HP is 1.5kW, that is a considerable amount of power to use just for a water pump. For most applications a 750W (0.75kW) pump is more than enough. Half the power = half the cost to run.

I'm guessing your wanting to pump water through a recirculating system or are you pumping from a stream through your system and out
I use a 12 volt in line self priming caravan pump from BCF I think it cost 80 to 100 $$ I few year ago.
It runs a ltr a minute thru my pda1 for any thing from 4 to 10 hours has once a month on average for nearly four years. Still going well.
Only took it apart once to clean some crud that had fallen into my coolant bucket and gummed it up.
Wow just looked it up on their site It's gone up $125 Jabsco Par-Max Pump - 4.3LPM, 12V
At least I think this is the one I use

Ps :think: mind you if you win the biding at .99 cents it'd be a beasty for $30 wouldn't it :music-deathmetal:

Transfer pump at Bunnings $79
3000 ltrs an hour.

I just did my cooling system this week.
Have a look at the last page of "Steampunk the build" and you will see what I mean.

Total cost including a 300ltr tank, pipe and all the fittings .... around $360

as dominator says its a bit of an overkill.
I use a bilge pump, 500GPH (so about 1800L) and it works really well. plugged into a DC power supply. the whole set-up cost me about $30. all purchased from ebay :)

Not sure if your comment is regarding the original post or mine.

My set up definitely is overkill
It's what was available quickly and so I went for it.

The amount going to the still is negligible, then again -
I'm going to run a fountain off it as well.
Added to that - I am looking at getting a rainwater tank so the pump will still be used for that.

Horses for courses.
