So you think a 2660 has enough ummmpffff otherwise known as PSI or CFM to turn 1.8 million gallons of water? Does that even sound right for a 1.2 acre pond at 4.5 average depth. Deepest 9ft currently, will be 18ft or so once dam work is complete.
Let me just ask ya....how would you set it up? I only have the Thomas pump 2660 as of right now. Horse stalls in between both ponds and want to aerate both at minimal expense but be effective.
Question, will that pump be strong enough? Specs listed are 4.5 CFM and 45 max PSI.
Figure that there is 0.5 psi pressure for every foot of water that is over the deepest diffuser. How deep will the diffusers be?
Once you have that number, then look at the pressure vs. volume curve of the pump. Will the pump furnish 1 cfm of air to each diffuser disc at that pressure?
That will answer the question "will that pump be strong enough?"
Here, I'll do the math for you.
1.2 surface acres
Max depth 18 feet
Average depth 9 ft (better to err on the high side .vs the low side)
9 x 1.2 = 10.8 x 325,851 = 3,519,191 gallons of water.
Using that information, you will have to determine how many CFM that Thomas pump will furnish at 9 psi.
Once you have that info., you have to look at your diffuser suppliers specs to see how many CFM the diffuser needs to operate, AND at what depth they will be placed.
Using that information, you can look at the mfg. specs and see how many diffusers you need, and at what depth they will be placed at.
Lets taka a look at Vertex Diffusers:
An XL2 will lift 4,550 GPM at 2 cfm@9 psi. You'd need to run it a minimum of 13 hrs per day to turn the pond over once. 3,519,191 � 4,550 = 773�60 = 12.89 hours.
But, since one diffuser station won't properly aerate a whole 1.2 surface acres, you have to run more than one diffuser assembly. AND since you really should turn the pond volume over more than once per 24 hr. period, you will need to run it at least 18 hrs. per day.
Now, with that said, if you don't use Vertex diffusers, I cannot say whether it will work or not. I don't know the specs of the pump you are wanting to use.
That pump you listed? You said 4.5 cfm
AND 45 psi max. Not 4.5 cfm
AT 45 psi max.
I/you need to know the cfm
AT 9 psi.
