12 volt pump

Have a look at the shurflo range depending onhow much capacity you need it may do the trick.

these people seem to have lot of infopumps

BCF have a range of sump pumps. They are submersable and run off 12v DC

If money is not an option then I think you need a bore pump, eg

Sun Pump Submersible Bore Pump

no affiliation. But shop around, there are a few types of varying quality and lift levels.

Simple - go to your local marine supply shop and get a 12 volt bilge pump. They come in varyiing pumping capacities per hour. Not expensive and very efficient.

Don't forget some sort of suitable filter on the inlet and a way to keep it out of the crap at the bottom of the creek otherwise it will probably cark it fairly quickly.

To stop it gunging up buy a meter of nylon flyscreen at bunnings for a few bucks then tie it as a big bag around the whole pump. You will need to be gentle with it so you dont make holes in it but by having a larger area there in less flow per cm sq and less "gunge suck".

By the way - love the photo of the J.

I have this set up. It consists of a flowjet pump like this one.

It is connected to a normal garden hose about 5 m long with a filter on the end, a 7AH battery and a 18m length of wind up hose like this.

And a normal garden spray trigger handle jet.

The flowjet has a pressure switch built in.

If the river is clear and flowing I just throw the hose in it and put the pump and battery on the river bank. Then run the wind up hose to the camp site.
I just press the trigger when I want water and it flows at about 12 l per minute. ( 2 1/2 buckets per min.). It self primes and lifts the water 2 - 3 m to the pump and a further 4 - 5 m to the end of the hose.

The water jet will go about 10m in the air. It is like low pressure water mains.

the 7AH battery will last about 2 - 3 days.
