Help With Pump Identification

[Dr. Dan]

I have this pump in my surplus inventory, and can not for the life of me find any specs or manufactures information on it. At some point it was sent out to be rebuilt, and when it was put back in inventory nobody documented the unit. Any help would be greatly appreciated.

Thanks,
Dan

Sometimes its possible to do all the right things and still get bad results

I don't think this is one of those on the link you posted. Here is another photo.

Thanks,

From the design and color I would guess that is a fire water pump. There is printing on the castings. Why no picture of what is printed?

 

[Dr. Dan]

Here is a photo of the printing on the casing.

Thanks,

The design of the bearing housings makes me think it's an Aurora. You might be able to get your local Aurora person to identify that pattern number on the casing.

The 3 largest makers of splitcase fire pumps in the past have been: Aurora, Peerless, and Patterson. Looks most like a Peerless to me.

That 2nd pic with the gussets welded on the bonnet are kinda strange. I don't ever recall seeing any of those. Makes me think it is either after the fact add-on or some cheapo,Chinese knock-off.

I believe the number on your casting would be from the foundry and not frothe manufacturer.

Let us know if you find out.

Just a note on the numbers on the casting: Goulds (for example; I know the pump in this picture is not a Goulds) puts the pattern number on their casings in exactly that way, so if you ever find a Goulds pump, and you can only read those cast-in numbers, a proper Goulds rep can identify the pump model/size by the pattern number. Years ago, they even printed a listing of pattern numbers so that reps could identify pumps by that information if necessary.

There is a national standard for firewater pumps. It is NFPA 20.
I believe all manufacturers must comply.
This pumps generally take suction on an atmospheric tank and discharge about 125 PSIG.
NFPA 20 has a table of capacity (GPM) versus nozzle size.
Measure flange OD and find Nominal Pipe Size in ASME B16.5 or a flange catalog.
NFPA 20 requires these pumpd be performance tested and UL/FM labeled
