I have what appears to be an Emglo KU pump on a compressor with no motor. What size HP/RPM electric motor should I use? What size diameter pulley should go with it ? Is there a missing filter on the head of this pump as shown in the last picture? Appears to be older than 2005, is this a continuous type motor.

Your ku should have a real 1.5 or two horsepower Electric motor, 15 or twenty amps

You might get away with a 80CC or so (~3HP), but for the price diff I'm seeing looking around right now, you might wanna play safe and get something closer to 200CC (6-7HP). It might use a little more gas, but will probably last longer.

Ya know, I can't really tell, but I'm starting to think this isn't a KU -

Maybe you can get some better pictures? The intake on the KUs in the parts catalogs appears to be a pipe fitting off the head and parallel to the flywheel.

Might be a good idea to talk to one of the on-line parts places to see if you can verify exactly what you have there.

KU motor size / Intake Filter
by: Benny

Thanks for the info!
I can now find a electric motor maybe a 2 or 3 HP with a fixed RPM and than figure out the size pulley to get in the Spec. range. My other concern is the intake area/filter. As seen in the pictures, it has an opening of about a 1" x 5" opening. Is it missing an adapter plate or something? Maybe I'll just cover it with scotchbrite pads....

Motor mystery?
by: Doug in s.d.ca

The pulley size depends on how big the motor is and what speed it runs at.

The pump is operated at 500-1100 rpm.

Decide your motor (5-6HP or less) depending on how much air and electricity you have available.

Then you can decide on your pulley.

From the images of the KU pump I've seen, yours definitely appears to be missing the intake filter, Benny. See the image I uploaded after yours.

The info I found shows it driven by a 1-2 HP motor. That seems a bit small to me.

If I had 240 volts available, and it were my compressor, I'd go at least 3HP and might even go 5 HP if price weren't an issue.

Anyone else?
