Here's a step-by-step instructions on how to build your own dosing pump which I created approx 2 years ago.

[Lost Boys]

Where did you get the dosing pumps from?

[Keith]

Here you go. This is where I've bought from in the past.

You are better off buying from here now as they are £10 cheaper

Cheaper same pump

[Keith]

Pump looks the same but the motor is different 240v - v -24v. You would need a transformer for the latter. It may enable controlability though.

[Si Clark]

Yes if you use a variable output transformer you would then make pump variable flow They aren't expensive from somewhere like Maplins or RS

[SLAPPY]

Thanks Keith, yes that's where I bought mine from.

I also bought the 24v models to make auto top up units.

bump...

my sp3000 is playing up and am looking at getting a 24v version of these
can anyone using one and point me in the right direction as to which power supply/ transformer - cant find anything suitable

[SLAPPY]

I used an old power supply from a Dell laptop which is 18v.

[andyseatrout]

Looks like a great idea to me.

Forgive my stupidity, but what would you use to control these?

[SLAPPY]

I haven't one was wired to a float switch for top ups and the other is rigged up as a spare dosing pump in case I needed it for anything.

thanks slappy, I was looking for a 24v power supply. if an 18v supply works I will get one of those

Thanks

I don't have a spare as otherwise you could of had one, there are a limited number of laptops that I can pinch power supplies from.

no worries there slappy people throw them out when the get a bit old, saying that the missus has a laptop that isnt being used much

I was thinking of getting a diy electronic timer kit that I could fit in the enclosure, hook it up to the pump, that way I could have a variable pump with a built in timer.
if only it was that easy

might just go for a 240v version in the end, have a cr sitting there doing nothing at the moment - bit useless without a dosing pump, already fed up of dosing chemicals manually

I know the feeling.
