I need help to find out what pump I need to replace the one I have. I don't know how to find out the gph.

This is the pump I have: a. o. smith universal electric motor 115v 60hz 1.8a 1550 rpm .14hp serial 067071m model jf2k024n'

I'm fairly certain the info you have posted is for the motor and not the pump.

Can you post pics of your motor and pump?

I'm assuming this is an external motor/pump unit.

Yes it is the motor on an external pump with a 2" inlet and 1.5" outlet. Here are pics.

Thanks for the pics. Is there an I.D. plate on the pump section?

I see from the info you posted that this may be an EasyPro unit. Cursory search online brings up the EasyPro Pond website and the model 3600gph EX Series. The inlet is 2" and outlet 1.5" but the specs state a 1.4A and not 1.8A unit which may not really make that much of a difference.

Did you buy the unit new or used?

I've looked everywhere and can't find an ID number. It is an old used pump. It was working with bthe setup I have but it's leaking and no matter how much we've tightened it it continues to leak.
 
Another suggestion is decide how much turnover you want and select from the many available pumps too. You may need to replace the inlet and outlet PVC connection based on the replacement. You might even want to look into DC pumps so you can adjust flow via the controller.

I know this doesn't address your original question, but I think worth considering.

Are you able to shut off with ball valve or equivalent? You may need to rethread. Make your there are no hairline crack in the PVC, etc.
 
Thanks again Heidi! I agree with DN328 that you may need to consider his/her suggestions for buying new. Choosing a pump for your application is not something I'm familiar with doing and defer to the members with more experience.

I see quite a few members using Dart or Hammerhead pumps and the newer DC pumps seem to be popular.

Sorry I couldn't be more helpful.

There is a backflow and shutoff. The pvc isn't leaking. It's leaking where the pump and motor meet or under the actual pump. It is very hard to tell which. I cannot change the pvc fittings to accomidate a different size inlet/outlet pump.

I talked with marinedepot they couldn't help me get an accurate gph and directed me to their high end pump which requires changing out the pvc. :( I stupidly purchased a reeflo dart from marinedepot but they said they are worried it won't work for my setup and I can't return it if we use it. I need to figure out an accurate gph.

Ah, ok. I assumed the connection between the PVC and pump when you mentioned tightening to no avail.

Perhaps I'm missing some key points. If you had to adjust the outlet or inlet on the PVC for a new pump there are adaptors the adjust the size. For example when I split my 1.25" return to two 3/4", I used an adapter at the T. You should be able to do this without having to replace you entire plumping.

Why weren't you able to use reefflo?
