I think you are rushing into this, based on what you have written, and I think you will regret it later.

Are you sure that's right? That number's not of the Ametek website and the number isn't consistent with Ametek's normal part numbering scheme, a typical Ametek number is of the form 11xxxx-xx or 12xxxx-xx

Yes. The seller sells quite a few "what are listed as Ametek"
Page of this thread and the links to the auctions are there.

The numbering supplied for second-line engines, vacuum cleaner manufacturers such as Electrolux in no way is found in Ametek tables. I do not know why but I stayed hours looking for that information. I believe that these engines are not made in America, but in China.
And they are manufactured under license of Ametek but are forbidden to provide detailed technical information. Especially in most of the world is not used as a parameter CFM suction capacity but is used Watts.

Single stage motors are generally more efficient at lower back pressures.
Two stage motors generally more efficient at higher back pressures.

Where we are working at around 44 inches, puts us in about the middle of the pressure range, where either type could be better or worse than the other.
You need to eyeball the pressure flow curve to determine the efficiency at 44 inches to judge.
CFM per amp at 44 inches is the bottom line.

For 220-240 volt motors 8 to 16 CFM per amp covers the range you are likely to see.
For 110-120 volt motors 4 to 8 CFM per amp because with only half the voltage, the motors can only develop half the drive power for the same current.

I rang them and their distributor near my area is too expensive. £68.00 each

If only the ebay ones listed the part no's.

It looks very similar in appearance.

Difficult to say for sure.
But you could always buy just one and then test it yourself.
