EHEIM 2260/1260 Impeller CHEAP, WHERE?

[TakeNotes]

For some reason I cannot use the "quote" function.

Ill try again in a bit as I want to asnwer all ur questions but cannot remember them without looking at them.

The pump in question is on the left. The one on the right is 1260. The left pump has a far larger threaded outlet.

I got the pump with these two outlet sizes. Both screw in fine. One uses the 1" hose and the other converts to 3/4". Still too large to run my hydor inline heaters on.

Can we agree this is a 1262 pump? Will try the bucket method later today.

What I need is the eheim part number that goes from my larger than 1260 outlet (on top) and becomes 3/4" so I can run my inline heater. The piece I have is not eheim and has too much meat on the 3/4 end which makes connecting the hose to it a headache. My piece is in back and 3/4 out from my 1260 is in front.

WOW, thanks for the pics as they really help me understand the problem. I will have to say that that is NOT a stock Eheim 1262 pump due to the size of the threaded fitting. It's possible that it was a custom design or a different model pump since the standard threads on the 1260/62/64 pumps are G 3/4" for the intake and output fitting and are German threads.

What I would do is get a 1" x 5/8" barb reducer adaptor and use the 'large' fitting the pump came with, a short piece of 1" hose to the adaptor and then use 5/8" hose from the adaptor to the Hydor heater. Be sure & use hose clamps to secure the hose to each end of the reducer adaptor so the hoses won't pop off.

Do you happen to have a Killawatt meter so you can check the wattage of the used pump or even a clamp on amp meter that electricians use for checking wiring? This may help narrow down which pump you actually have because the 1260 pump is 65 watts, the 1262 is 80 watts and the 1264 is 100 watts.

I do not have a meter to measure watts. I'm going to run the bucket test to measure the water flow because now I'm stumped. Lol Id looooooove for this to be a 1200gph but that's plus my other 600gph would be massive overkill on my 150 breeder. I took a knife to the output that it hame with and took some meat off and then fine grit sanded it down to try and press the hose over it. Will text flow and see if my mod help with not using reducers etc. If this is the 1264 id be worried about nnarrowing the output too much. Should I be?

It should not be a problem to reduce the flow if it is the larger pump.

You could always use 1" hose and a wye fitting to split the output into 2 different streams. I found that 3/4" pvc pipe inserts very nicely into the 1" Eheim hose for my DIY intake J-tube. You could try something similar for your situation as the 3/4" pvc parts and reducers are easily available at home improvement stores.

I did the half a 5 gallon bucket test about 10 times with mixed results from 11 to 14 seconds. I'm stumped.

OK. I have 3 2260 pumps (as per the label) I noticed that two of them running on my canister all have the 1" output that converts to the 5/8" hose. SO this pump in question has the same lip on the outer rim as the other 3 and the same output.

I'm going to say I have 3 oddball 2260 pumps and one 2260 pump that has the smaller 3/4 output.

Are the "cooling" groves indicative of a specific model number or do some have it and some don't. I'm sure some of the 4 pumps I have are fairly old.

Did a more accurate measurement of the half way mark on the 5 gallon bucket and the gph test results in 14seconds or so. SO the pump is a wacko 2260 which has a 1" outlet. I sanded down the output piece and have it up and running on a 2250 canister since its not the 1262 and I'm already running 1260s on my main tank.

Using the old 2250 pump for water changes now.

THANK YOU ALL FOR YOUR HELP.

Well your bucket test averages about 818 GPH (2.5 gallons/11 sec x 60 sec x 60 minutes) so it is probably a 1262 pump.

I'd love to see a pic of the filters that have that 1" output to 5/8" hose conversion. I own one new (in 2005) 2260 (w/1260 pump), three used 2260's (w/two 1260 and one 1262 pumps) and one used 2260(w/1060 pump). All these pumps have the 5/8" hose output with the G 3/4" thread screwing the fitting into the pump.

The number of cooling grooves may be indicative of an older model pump. I think one of my 1260 pumps only has the one cooling channel instead of two. I'll check them next time they are due for cleaning.

Do you have any idea of the age of the pumps?

Edit, with those new measurements, it is probably a 1260 pump because its stated output at 0 head is 635 GPH.

Just for the heck of it, what is the model of the pump from the 2250 filter? Sometimes the label will read as follows: TYP 2260, PUMPE 1260. Other times it just lumps the pump in with the filter model.

You are very welcome. I love trying to troubleshoot this kind of stuff. Pictures are always helpful and can really make a difference when figuring out problems or products. I think it also makes you more aware when you need to troubleshoot problems with equipment if you have a bit of in depth information.
