Which Water Pump?

Squidd,
The problem with these low pressure pumps is that you need to use big pipe to get big flow..You can move a lot of water through 1.5" pipe using these pumps but once you drop down the pipe size you drop the flow A LOT... it'll still out perform 600 gal of flow using one amp.
Take a look at Customaquatics web site..They list the flow chart and the wattage use for the Sequence Stingray model..I really like that pump... The DART model is another one that looks good and the price is really good but the intake fitting is 2"...
I will be getting the Stingray soon...I have seen a few of these and the Dart's in action. IMO, their a better pump then the AM's.. Don't get me wrong. I like my AM3K, I just like the price and the wet end seals on the Sequnce pumps better.

That's kind of what I was referring to with the "moving out of the orchard and not looking at apples"...
In the sizes of pumps 600-900-1200 and the sizes of plumbing 1/2"-3/4"-1" that the "majority" of people are looking at/using, the flow to watt ratio will be fairly consistent for "X" amount...( a couple watts up or down is minor)
When you get into "big flow" pumps with large 1 1/2"-2" plumbing things are a little different...
But, not everyone needs or can use 2400-3000 gph (yet :D )
"Quick math"...(no decimal point)...
The 660 gph pumps range 70 to 100 watt with some in the 80-90 range...lets give it an 85 watt average...(+/- 15 watts is minor)
660 / 85 = 8 gph per watt..
In the same vein the 480 pump jjboods looked at runs 50 watt (some at 70, give it a 60 watt avg...)
480 / 60 = 8 gph per watt...
Not much difference in watt per gph (even if you run decimals out)
Basicly, it take "X" amount of power to move "X" amount of water...
On the other hand the pumps your talking about... 2400 gph at 110 watt are running 21 gph per watt
And that is a big difference...:yes:

I'll agree to disagree, a pumps a pump and an amps an amp..the AM's and sequence will move a hec of a lot more water through 3/4" and 1" pipe using the same or less juice.

So I guess your saying you should go back and throw out this statement you made ......

Minor or big?

No,
I'm saying that it confirms the "statement" when looking at the smaller pumps/pipes most of us use...(apples)
But, when we look at the "larger" flow pumps, things change...
If you "restricted" the larger pump down to 660 gph it would still use 1 amp...so you really haven't gained anything...
Actually I thought we were agreeing (at least I agree) that the larger pump/pipe systems ARE more efficient, but then we're not talking about apples anymore...
Show me a pump that is in the 660 gph range that will do 21 gph per amp..?
I will change the statement from as far as "Basic Physics" because that is too all encompassing and "limit" it to "Basic Pump Design Parameters"
Because if you really want to get technical...we get out of the "impeller" pumps and into hydrostatic "gear" pumps...they'll blow Both or numbers out of the water...
But then, they are not "apples" either...:D

you know your reaching big time here....you didn't mention "pumpspipes " until after I corrected you

I don't see what this has to do with this statement...
"You will find it takes about the same amount of wattage to flow "X" amount of water, no matter whose pump you use...That's basic physics..."

it seems there only apples when you say there apples...

All right, I give, you win ...
:D (sort of)
Taken out of "context" the statement is incorrect (actually the "terminology"per "Laws of Physics" is incorrect and misleading) and I retract it and apologize for any "confusion" it may have caused...
And I further state that "All pumps are apples"..
Will you please forgive me..? :)
However...
In the "context" of the smaller pump/pipe "parameters" The wattage differences are "minor"
Change the "parameters" and the difference can be "big"...
Now, show me a pump that is in the "parameters" (660gph@4') that runs at the "effeciency" level of the "other parameter" pumps...ie" 21 gph per watt...vs. 8 gph per watt...

again and again I'll say it...this is the only statement I commented on....apples are apples and pumps are pumps.
How about if I show you an apple that's 1/2 pound and another thats 1/4 pound...

Ok, I think I'm getting it ...:thinking:
Apples are Apples (1/4lb-1/2lb doesn't matter) and Pumps are Pumps...
So...
And I further state that "All pumps are apples"..
Is another "incorrect" statement...:eek: Man, I am really screwing up today...:D
I hearby state that "All pumps are NOT Apples"
Damn, Now you really got me contradicting myself...:notsure:
Anyway,
I still think we are in agreement that "different parameter" pumps CAN have different effeciency ratios...Big ones even...:yes:
My intent "way the Hell back there" was not to prove a basic physics law but that when looking for a pump at the level or parameters or "whatever you want to call them" that he was...
The differences in effeciency will be "minor" and to caution him in the "interpratation" (read between the lines) of MFG specs.
If that is not true...then, (and I'll say it again)...
"show me a pump that is in the "parameters" (660gph@4') that runs at the "effeciency" level of the "other parameter" pumps...ie" 21 gph per watt...vs. 8 gph per watt...
Because that would be BIG...

oh, so now I'm supposed to be a $#@&^* mind reader

I just got back from the Supermarket, they had no apples but they did pumps...all kinds of pumps in the same bin:D

Well Yes Actually...
I know I'm "Transmitting"....:thinking:
If your not "Recieving"...The problem is at Your end... :notsure:
... It's all good...really....:rolleyes:

&@!&.....
we were having so much fun I forgot to ask. Did you check out that Sequence Stingray pump? Just wondering what you think about the wattage chart ..its a med pressure pump that will do about 4500 gal at 6 feet of head and use 120 watts....
Just checked, the Stingray isn't listed anymore, looks like the Hamerhead replaced it...that looks like one hec of a pump

That's OK...I forgive you...That wasn't so hard was it...?
Did you have to "spit" on the ground after typing it...Like I did...??

No I haven't yet...Got "hung up" on the Amp Masters and then started planning my next tank and what I would put in it and where I was going to sleep after Mrs Squidd "Kicks" me out...

I know you "can't tell me" where subliminal to find hint them ...
So I guess I'll just have to do a "search"...

Never mind I found it ...about 22 posts up.. :D
Maybe we should tell jjboods about the pump he was "asking" about...:yes:
