Solar pump required.Hello.
I wish to put a pipe in a stream and suck water out of it into a cattle drinking trough. The rise from stream bottom to trough is about four metres, and the trough sits ten metres from the stream bed.
The pump is to be driven by solar power.
I appear to have a decent budget for this project, but no idea what I want to do it. I'm after you lot to provide full solutions. These can be off the shelf, or assembled from components.
In a perfect world, I need it by the end of Feb, and I have, around £1,500 to do this.
Away, my little downsize technologists, and find me a solution, please!

Great. And within spitting distance! How could I not find that?
Thanks.

How much water do you anticipate pumping per day? And does it need to work in all weathers? How will you switch it off when the trough is full? Or will you set up an over-flow from the trough back in to the stream?

No. Ram pumps require at least some water movement, and although that's what my grant is for, I am allowed to use it for solar, instead, because a ram will not work.
I need it to work in all weather if possible. I am happy to include water storage, a trough, and so on, into the price. The stream never completely dries, nor freezes.
I had envisaged a pump it the stream, run by panels and batteries, pumping up, into a trough. And an overflow back into the stream, preventing the trough from over flowing, but allowing water to be changed and kept fresh.
I have an appointment with the guys above tomorrow morning.

Sounds good.

Damn (or dam even), look like a brilliant bit of kit

Yes, they're very smart. But do require at least slight movement. When it's dry here, and the cows need it most, we can remain still.

How much water are you talking about?
Will you be allowed to discharge the over flow into the stream?
Why not use float switches on the main storage tank to control the pump?

I'm filling a drinking trough for cattle, less than a dozen dexters, not being milked. I can include storage. The overflow has come from the stream, it can go back there.
Im Happy to use float switches or whatever. I don't know, hence why I'm asking for solutions.  . Feel free to design and specify a system.

float switch would save power and pump wear but a contstant flow would be less likely to freeze ,airlock etc
a 4 m lift is the biggest factor
if we assume 20 litre per moo and 12 moos =240 l
if constant feed at 20l per hour tank stays full
or
switched at a higher flow
20l per h isnt a high flow so a high pressure low vol pump should work
maybe high pressure hydroponic pump would work if the intake is clean

Keeping an eye on this thread.
I have a natural spring at the farm, unknown depth, (must find out), it's about 3' in diameter. It has never frozen in my lifetime. It is tile lined.
I need water to go about 25 yards to get past a damp area. There is about a 3* slope over the 25 yards.

Had a chat to my brother (PFS Helston), his response was
"Solar pumping systems are more than likely going to cost more than this. I possibly could do a Drive Pack which is Pump and Controller only for about £ 1600.00 plus VAT with the customer supplying pipe, fittings and solar panels etc. Also bear in mind cubic metre of concrete to site panel.
20 gallon going to be too small, need to remember dull days, therefore storage is the key. Plus don't know how many head need to feed.
Should really be thinking at least double the budget. Just because it's free running does not make it cheap to buy.
If supplying to cattle or horses why not consider 1 or 2 of the Aquamat pasture pump, cost about £ 276.00 each plus bits and bobs etc."
This might help / be of use

i have seen something similar in a gb mookit porn but i cant remember which one
recon dexters are clever enough to use one ?

We have one of these already. and they used it withing seconds.

I have storage of 2000 litres if needed, and a pump plus panels is around 700 quid. Would seem to meet my needs. However, the grant awarders have decided that even though my answer would save them a grand, I have to have a ram pump as that's what it says on the paperwork. It won't work, and the cattle will then walk in the stream, but the auditers will be happy.
I've been told I can buy one IF the supplier will simply call it a pump.
Wonder if they're proud of the work they do.

No problem Nick
If you need any advice, give him a ring?

Can you get the pipe in the stream at a higher point than the trough and use gravity? Siphons in and overflows out? Pumping from a stream wears out pumps very quickly. Grit and gravel get sucked in.
('Tis not me speaking, I haven't had enormous experience of pumping water. Tends to dominate life around here though.)

Mind someone doesn't take an attraction to the solar panels.
