I'm building a pond that uses raceway theory to raise a few fish, just for fun. The pump will need to move around 14,400-28,000 gallons/day. The head will be 10 feet. I'd like it to be somewhat quiet. I'd like it to be EXTREMELY reliable and low maintenance. I can provide any type of electrical service necessary. The electrician is coming out next week. Any suggestions?

Bruce, can you explain that in a little more detail for a newbe like me, and maybe others that might be interested? Thanks!

Raceway theory is "Keep the water fresh and moving". Basically it's high-level replacement rates.

Is the suction (inlet to the pump) flooded?

In addition to that, what are the dimensions, depth, proximity to current pond and I assume you're using the water from your existing pond? Such as, being pumped in one end of the raceway and exiting back in to your existing pond, via a below surface screened outlet? Thanks, I'm just trying to get a mental image of your idea. PS - sorry to get off-topic

Any suggestions? Can you reduce the head and use air to move the water instead? Would save you a lot on energy costs and would aerate the water at the same time. Pumping water through a raceway is very inefficient not to mention how much water is used. If you're using the lake how about a floating raceway using a linear air pump you can barely hear?

If pigs could fly bacon would be harder to come by and there would be a lot of damaged trees.

I just assumed there would be an inlet hose suspended off the end of my dock. I was planning on drawing water that was three feet or so below the surface.

That is correct.

Bruce, do I have this right?
3' suction to the pump (this rules out using a submersible pump).
10' elevation rise past the pump.
up to 28,000 gallons per day (19 gpm or 1166 gph).
I would look into the specs of the shallow well pumps. Put it in an enclosure at the pond, use some sound deadening material and make sure there is plenty of ventilation for keeping the motor cool. Lowes, Menards, Home Depot.

JKB is the man to ask about efficient water pumps... Looks like Scott (Esshup) knows a bit about it too.

Just browsing pumps. Looks like any of the 1/2 hp self priming centrifugal pumps would be more than adequate. May need a foot valve on some. I didn't look at any Chinese stuff I would go with mag drive for reliability. Here's an example: http://www.iwakiamerica.com/products/SMX.htmI'm not suggesting you buy this, it's just an example. You could also hang a submersible pump off your dock, but you'll need one that has a continuous duty cycle (means it can run 100% of the time) They do make submersible pumps for Aquaculture/Irrigation that you can just drop in a river or lake, but they are a bit pricy. What I would do here is too complicated for a short term setup. If it's gonna run for years and needs to be as energy efficient as possible as well as reliable, then I have other considerations. Sounds like fun tho!

A submersible pond pump hanging off your dock would be the easiest thing.

I've used sump pumps mounted inside a five gallon bucket, that I got from a local big box store to drain my ponds. Doubt they are rated for continuous use and may not be very efficient though. JKB?
Stoney Creek Equipment Company, an advertiser on the site, has a line of pumps as does Pentair/AES.
Any of the pumps rated for continuous use for waterfalls in Koi ponds would work.

Cecil, we're a distributor for Stoney Creek, and that's the first place that I looked for pump specs. None of the pumps (non submersible as Bruce said it was 3' from the water to the pump) were small enough for Bruces needs. All pumped way more water than what he needs.

Completely unrelated post here but thank you for mentioning the raceway system. Explained a question I have long had about why a series of ponds was named what it was in a place that I hunt. Always baffled me.

Yeah, those are just for temporary applications. Not something you need to be reliable. I'm really liking those Iwaki pumps tho. Two of the 1HP pumps, 22X and 44Y would only require a fraction of the consumed watts to pull off Bruce's gig, as the 1/2HP would be going balls to the wall. The charts most post are for fairly decent estimation. If it's a real project, then the flood gates of info will open. Too many inquiring minds on the internet that muck up the works.

I would like to see that 98.1% efficient single phase motor.

I guess I missed the part about it had to be non-submersible. IMHO non-submersible is not the way to go if one wants a quiet pump.

That's why I suggested a shallow well pump. In places where they still have shallow 2" wells, some houses have the pump and bladder tank in the basement. They're pretty durn quiet. JKB, I'll show you the pump. No guarantees that it IS 98.1% tho.....

All this discussion is good for me. It makes me seriously consider all possibilities. I'm even thinking of having horizontal circulation in the pond, then using a gas transfer pump to empty it, then refill it twice a month. I won't have very high fish density in it. It would sure save me money...and I'm not sure it would add to the overall maintenance requirements.

Bruce,
You mentioned a fishing thing where kids could fish. Are you sure the fish would be receptive in a tank/raceway situation? I've seen fish that won't bite in those situations and get spooky when people get around the tank. Especially fish that are not used to confinement.

I figured at 70 feet long, 14 feet wide and 3 feet deep, the fish would be unaware of our presence.

Bruce,
What kind of monsters do you plan to raise in there?
