Pond Boss Forums AERATION Systems questions great deal on a pump!

I use almost the same pump but in 115volt. I have used it for 3 years and run it all summer and have never had a single issue. The pond is 1100 feet away and I am running a double diffuser. Shop around but this is as good as it gets for the DIY systeam!

Excuse my ignorance, but is this really the kind of pump to use on an aeration system? Everything I've seen on pond supply sites is rotary vane, diaphragm, rocking piston, or linear. The one linked is a vacuum pump which is different, right?

I'd love to be wrong and pick one of these up for my DIY aeration system.

My understanding is a rotary vane and a vacuum pump is basically the same thing. Look at the CFM and Max PSI on the specs of that pump. It is almost identical to the pump that I have been using for 3 years. My system works great, and has yet to need any work other than a set of vane which I put in myself just for preventive reason the pump was still working fine. I pump to a double membrane diffuser 1100 feet from my pump. It uses very little electricity . Here is a picture of how I set it up.

I suggest you run a cooling fan and install a filter and PR valve. you can run air a long distance. here is a pic of the run and the box that the pump sits in I also have it on a automatic timer

That's great! Thanks. Sure beats buying one for almost 10x the cost elsewhere.

How loud is it?

Gast vane pumps usually run very quietly.

I just bought a well made dual piston spray art pump, oilless for $85 at Northern tools I am going to try out. That is a great deal for an 0522 even if it last 1 or 2 yrs. I would order a set of vanes and have handy.

Problem with that pump, for my application anyway, is that it is 230 vac and I have 115 to my pond. I have been watching that particular web site for months now to see if they get a 115vac system....to no avail. Here is a previous post I had made along those lines and I am still in need of a 115 vac pump....

"Just wondering if anyone knows of a source for GAST air compressors. I bought a 1532(115 VAC, 1.5 cfm) from C and H Sales several years ago at less than $50, but they are apparently no longer in business. According to the GAST web site, they still make that compressor but I cannot find a source for them w/o going to the GAST sales rep which I would rather not do. That size and price was perfect for my one acre pond in which I have a vertex aerator installed....but, need to replace the air compressor."

Thanks in advance....

Dick, if you can put a breaker box at the pond to split off your 110 service, you can simply rewire the current supply line to 220. It's a very easy job and would probably cost under $200 even if you had to hire a pro. If you do it yourself, be sure to reduce the 220 breaker to 1/2 of the current one.

another great deal

I have seen the pumps on this site but I wonder why the air filter is different then those (on the same Gast pumps) that I see on other sites. I have a dusty location and I want the best filter, any recommendations?

That filter is for very clean conditions as it does not filter much. Look into a Gast glass jar muffler/airfilter or a Solberg 8cfm model filter muffler.We currently use the Solberg Hi capacity model on the Gast 0523/1023 and the glass jar model on the 1 hp Gast 1423,

I need to replace my old pump,and the price of this one looks good. Only problem is that it is 220. I have an old hot tub out back of the house that I have not used for years that is wired to 220. Thinking of taking the heater out of the hot tub and installing this in its place and running airline 150 ft to the pond. Not much of an electric kinda guy but did run the 220 to the tub 20 years ago. Seems like I recall that running motors off 220 is cheaper than 110. Is that correct? Any advice on how to wire this up GFI, fuse, exctra? Thanks

It is not cheaper to run on 220. It just pulls less amps. The watts (what you pay for) are the same.

If it's a really long electric run, 220 might be a scant few % cheaper than 110 due to lower line loss.

I work in a printshop and we took apart this old Rosback Collator. It had one of these motor/pumps attached to it. The date on it is June '95. It's in great shape (looks new). If anyone is interested in it, let me know.
