Pond Boss Forums AERATION Systems questions Aerator Replacement

Our 1/3 hp GAST 0523-1010-G582DX bit the dust over the winter and I'm looking for a new one. We've checked Stoney Creek and Grainger, but am a little sticker shocked at the $450 price tag. Does anyone have any ideas for locating a replacement at a cheaper price? Ideally we'd like a another rotary vane aerator of same size. I found one at biosurplus.com for $250 but I have no idea on their reputation.

Thanks

Hi cool,welcome to Pondboss.There are several folks onhere that are in the areation business and Im sure they will be chiming in.Are you sure yours cant be fixed?I bought from one of the venders here and he told me when I had trouble it was ussually the same problem,to call and let him know,and he would send me the parts to fix.Please be patient,Im sure they are working,but will chime in later today or early in the morning.

cool, check our refubished page and new stock pages. I have a GE 115 volt 1/3 hp 0523 101Q G582DX rebuild that will go on the "refurbished page" in the next day or so for same price as the 1/4 hp currently listed.New GAST 1/4 hp 0523 are in the $349 range.

I bought a back up pump here and they were great to work with!

The gast vac pump is the one you want. I am going to switch my 120volt out for the 220 as it draws less amps and I am only running 8 hours a day right now, but soon will go to 24/7 and the lower amp should be a little bit cheaper to run.

IIRC, equal HP pumps draw the same power regardless of voltage.

ie 10 amps at 110v = 5 amps at 220v A 220v line is merely two 110 lines with each drawing half the power.

Rainman has it right. The good old law of ohms never lies.

With half the amps, you gain efficiency. Using a 220 pump there is less energy lost to heat in the wires, smaller guage wire can be used, lighter switches, etc. Where available 220 is the way to go.

It will help to balance out the electric panel. I'm an electrical dummy, so my contractor 'splained it to me. The electric company here charges us for the maximum amount of current used, no matter what leg it is on. So, he says he balances out the electric panel and that helps save $$ for the homeowners (we're talking 110 here, not 220 because it draws from each leg equally)

He looked at my parents house, and the panel showed all the "idle" electrical appliances were drawing power from one side of the panel. 20 amps IIRC. So, he swapped a few circuits, and now each leg draws 10 amps, effectively cutting my parents electric bill in half (as he explained it.)

Is that correct or is he feeding me a line?

Scott, you are still drawing 20 amps total. It MAY reduce the bill a little since there will be a little less heat. Heat adds resistance (ohms) to current flow and requires a bit more amperage to push through and reduces the actual voltage reaching the appliance. Amps times ohms equal voltage.

Rex:

So I WAS getting fed a line of BS! Thanks.

Got an idea when you'll be swinging by?

Looking like the delivery will be near the end of October so John can get more done on his pond before stocking.
