12v solar dirty water pump with float switch...

johngalway

Where the hell do I find an item like that

Needs to be solar powered as there's no power on site.

Needs to be able to handle dirty water such as bog/marsh water.

Needs to have a float switch as it'll be left to it's own devices to do it's business.

Needs to be able to lift water up 10 meters minimum, 20 would be great.

Needs to be cheep, like the budgie

I can find dirty water pumps that aren't 12v.
I can find 12v pumps that aren't for dirty water.
I can find 12v dirty water pumps for fountains which won't "lift" water :rolleyes:

Any useful suggestions or links appreciated

would a bilge pump from a boat do you? try ebay for if so. that would be dirty enough water id say, i think you can forget about solar though, if its 12v hook it up to car battery

I'm not sure it could handle the lift? The solar idea is that a panel would be attached to a battery to top it up, the float switch then would turn on and knock off the pump as the water level rises or falls.

You should put that in the plumbing section John. Might be worth giving EPS in Ballyhaunis a call too.

Check this bilge pump out:

You could install some type of strainer around it to prevent it from taking in too big of dirt particles - but its made for pumping dirty water from boats.#

Check out this 12v solar panel:

It would keep a used tractor battery or 2 topped up and surely keep your pump running.

There are loads of cheap options on float switches. Have a look at this one:

Hope that helps.

I see on the journal (classified) connachtagri.ie do a solar powered subversive water pump..

Sorry Jerdee, just saw this.

No, I've not done anything else about it yet.

I was going to try this aswell.
Firstly you don't need to worry about dirty water if you have a proper inlet filter on pump. You don't want dirty water anyway, so why pump it.
You'll have to match the output of the Solar Panel to that of the pump too.

I'll put up links for the different parts later when I get around to it.

Did anyone have any joy in getting this going?

If its a tank type situation where water is collected, then when it reaches the top of the tank, you want it emptying
You'll need two float switches one at the bottom of the tank, and one at the top, a twelve volt relay a twelve volt car battery and a boat bilge pump and a say forty watt solar panel.

It's no good just having a single float switch as it will be going on and off all the time as the water fluctuates by a couple of inches

So the idea is starting with an empty tank
As the water rises the bottom float switch switches on
The water continues to rise until the top float switch switches on
The top switch switches the relay on
One set of contacts is fed from the bottom switch and applies power to the pump, in parallel with this the second set of contacts keeps the relay energised so that the pump keeps running when the water level drops and the top switch switches off.
The pump is kept running by the relay latch powered by the bottom switch.
When the bottom switch switches off the pump stops, and waits for the tank to fill again, then the cycle repeats itself

I wouldn't be complicating things like that...

a simple float switch like on any sump-pump would do.. Vary the length of the cable and it will determine how full the tank gets before emptying down and stopping whenm the float lowers with the water level and stops the pump...

I installed many of these on farms in a past life and there is nothing to go wrong.. KISS (keep it simple stupid)

What make of a pump is that? Are they 12 volts?
