Pump selection for water colection

best pumps on the market have used these for years and never had one fail

If you have a 240v. gennie you might look at a submersable or a 12v. submersable if the body of water you are pumping from is large enough to accomodate the pump.
If you are using hoses to and from the pump then a shurflo triple diaphram 12v. is the go.50psi and what goes into the has to come outStan

Hi Theo,

I looked up the specification of the Flojet 4405-143 which states that the maximum output pressure is 35psi and that it self-primes up to 2.4m vertical lift.

35psi (approximately 2 times atmospheric pressure) corresponds to a vertical column of water approximately 20 metres high (using the approximation of 1 atmosphere equals 10 metres of water column).

This means that the pump in question needs to be no higher than 2.4 metres above the water you are pumping from. Further the total vertical height of the hose should be no more than 20 metres above the water you are pumping from, this includes the 2.4 metres to the pump.

You may want to put a filter on the inlet as I have had my pump clogged by sand and pieces of vegetation when I had no option but to pump from a shallow creek.

The 50psi pump recommended by Stan Pinko will pump up about an extra 10 metres in height.

Don't buy those submersible pumps, the red & white ones from camping stores as they are not truly submersible and you get an ingress of water after a time.

Thanks guys, to coin a phrase it looks like a suck it and see! I was having a robust discussion (fight) with the bride on the various hights we have encountered. we never agree on much hahaha. one trip we bucketted from Crystal Ck on the way to Verilia Point, I felt it was under 2 meters from the log bridge and she said it was more.

Domestically I know I'm wrong.

Kind regards

Theo

I've bought a little Honda 4 stroke 1" pump, it takes up little room in storage, uses almost no fuel, is very light and both the quantity of water and the lifting head are no problems.

We have a small 12v Flojet type pump, it is in a wooden box with a 40ah deep cycle battery , a 400mah solar panel sits on top of the box at a 45 degree angle and pointing north. 10m of air hose from from water to pump and 20M of air hose from pump to tap at camp site...lifts water up to about 2m or so o.k , fills a 9l bucket in about 1.5 minutes....we set it up and forget it , battery never goes flat.
