Sourdough?
I am interested in a water pump that would be capable of getting water from a stream or other watersuply near our camp site actually to our camp site. We have several favorite spots but all of which are a fair distance from the water source. ie up the hill 20'. Any suggestions?
 
~ 9 psi is all that is needed to generate that amount of hydraulic head..
 
Thank you Mace...all the pumps I have seen are for RV's and such, but none say how much verticle they will pull...not that I would know how to look. What if I wanted to be able to pull 40' would I double the PSI or is it more complicated?
 
2.307 ft of water per psi..

30 psi will push water up a hose almost 70 vertical feet..
 
Hi,

Here's what I use to have to fill my camper from any stream. I think I paid around 60.00$ 10 yrs ago though. You can't run it dry though..the best thing is to take a gallon jug and fill the hose from the uphill side (filling the pump) and then turn it on. It has a little rubber impellor that will burn up quick if run dry! I had it setup with 12# 20' leads and it worked great.

Nice thank you! How far away can a 12volt unit actually pull water? And is it better to have a larger draw line of thinner draw line? I have a friend who is retired ODF that said hose friction is an issue...
 
draw water???

You cannot suck more than 33' of vertical head..
 
Hose friction my foot!! lol I think the most hose I had on the stream side of the pump was 50' and the trailer side I think I had 15' It sure as hell was better than lugging water up the hill twice a day so the girls could take their showers...even found one of them washing dishes with the water running...JUST LIKE AT HOME!!..LOL
 
Thank you yet again Mace! How do you know so much about pumping water? ...you said head...:grinpimp:
 
Sureflow 3.5 gpm

Last time I used it I ran 100ft of hose to a small stream. No problem putting out 2gpm at about 10-15ft. Problem you run in to is the suction hose collapses. I was lucky in the crappy water hoses I bought were very stiff. Even better now a year later as they have gotten even harder.


Self priming and can run dry. ALso nice to get one with a pressure switch on it. cost me about 70 bucks I think.

Thank you I'll make sure to get s stiff hose :grinpimp: Yeah I said stiff hose :grinpimp:. Probably one of those no kink jobbies. And I'll look at the Sureflow!

My guess is that Mace has taken a fluid mechanics course. The first time in class when we discussed NPSH I could barely hold back a smile.

NPSH = Net Positive Suction Head... :)


Out of curiosity Mace, did you ever take any engineering courses? What type of work do you do if you don't mind me asking?
 
I have taken a couple of engineering courses.. But those engineering types are a bit much :D

So I still get to giggle about Cleavage ;)
