oO SKIPPY Oo Posted March 19, 2011 Report Share Posted March 19, 2011 hi all - are there any electricians that can help me out here - im looking at getting a pump - http://www.trademe.co.nz/Browse/Listing.aspx?id=362419346 which is 12v 12a so 144w - and i want to be about to plug this thing into the wall to be able to use it - i dont really want to have it powered by a car battery which i guess is my other option. so are there any step down transformers that go from 240v to 12v and still pass the 12a needed ? TIA Skip Quote Link to comment Share on other sites More sharing options...
Zayne Posted March 19, 2011 Report Share Posted March 19, 2011 why dont you just get like a sump pump would be cheaper + more powerful Quote Link to comment Share on other sites More sharing options...
oO SKIPPY Oo Posted March 19, 2011 Author Report Share Posted March 19, 2011 needs be able to suck up algae and leaves and turtle poop from the bottom - not sure a sump pump would handle it all without clogging up Quote Link to comment Share on other sites More sharing options...

TIA Skip You don't want a step down transformer, you want a 12v power supply. 12a is a pretty hefty amount of current, you'll probably do best with something like a converted PC power supply. Most others are either 1 amp range wall warts or couple amp laptop PSUs. This should work: http://www.trademe.co.nz/Business-farming-industry/Industrial/Electrical-equipment/Electronic-components/auction-361287412.htm Quote Link to comment Share on other sites More sharing options...
oO SKIPPY Oo Posted March 19, 2011 Author Report Share Posted March 19, 2011 cheers for the idea i will take a look into that - be nice if i could get a plug unit that was nice and tidy so i didnt need to worry about our daughter playing with it etc Quote Link to comment Share on other sites More sharing options...
suphew Posted March 19, 2011 Report Share Posted March 19, 2011 Since you already have 240v and a pump in your pond why don't you just add another diversion to that pump (or pull the hose off the waterfall) so it will pump out onto your lawn? How often do you plan on clearing out the pump? Most only do it once or twice a year at most, adding a 12v supply and pump seems like a lot of expense and effort to save yourself a couple of hours a couple of times a year.

oO SKIPPY Oo Posted March 19, 2011 Author Report Share Posted March 19, 2011 i have some of that algae that chris had in one of his cold water tanks - that stuff that just breaks up as you try to remove it - so i might be doing it more then a couple of times a year (bugger it). also that pump thats currently in there doesnt stretch to the other side of the pond (i mistake on my part when setting it all up) my idea for the new pump was to be able to just suck out the stuff from the bottom like a vacuum without having to stir it all up or remove the fish and turtles. that was a mission last time i did that Quote Link to comment Share on other sites More sharing options...
suphew Posted March 21, 2011 Report Share Posted March 21, 2011 Your current pump should let you attach a hose to the inlet, I have the fittings at work if you want to come and grab one. You could use this to suck the mucky stuff up, most 240v pond pumps will handle sludge and plant matter and even solids that aren't too big.

oO SKIPPY Oo Posted March 21, 2011 Author Report Share Posted March 21, 2011 hmmm hadn't thought about attaching a pipe to the end of the pump - DUH - this is the pump I currently have - http://www.hozelock.co.nz/aquatics/pumps/filter-pumps/titan/titan-3000.html i will take a look at it and see if i can just attach something to the inlet - looking at the spares diagram http://spares.hozelock.com/product/titan-3000/ there isnt much room to put anything on the end of the pump - i have had to pull grass etc out of the impellor housing so i know that it wont handle that sort of solid material - maybe it will handle that algae. you have those hozelock titan pumps in the shop to be able to pull apart ?

spoon Posted March 21, 2011 Report Share Posted March 21, 2011 that pump will handle solids up to 10mm depending on the mnodel you have otherwise get something like this http://www.pumpsonline.co.nz/submersibl ... -watt.html can handle solids up to 35mm Quote Link to comment Share on other sites More sharing options...
oO SKIPPY Oo Posted March 21, 2011 Author Report Share Posted March 21, 2011 i think mine will only do solids up to 4mm but i will give it a try if i can get some pipe for it on the weekend. I was looking at that sort of pump today but really i need something with a hose type inlet or someway i can attach a hose like mine so that i can use it as a vacuum to clean the bottom of the pond. Just been out and pulled the casing out from around my pump and it might do the trick so gotta find some hose the right size Quote Link to comment Share on other sites More sharing options...
