Gardner Denver air compressor pump question

Cleaning out the top of the loft at work I found an old gardner denver pump, big flywheel pulley, 2 groove.

I spun her by hand, she sucks and blows, sounds good.

The data plate was gone, but this was stamped under the 4 rivits where the plate was

1-ACD-9

Any ideas on how many HP I need to drive this? As best I recall we used this at work on a horizontal tank back in about 87, then the motor was stolen and we took the pump off and stored it, and tank was old and scrapped.

i have a spare upright 80g tank now.. just wondering what motor to power with?

we have single phase 220 service at the shop.

will 5hp pull this?

thanks
 

SG; you might get lucky at the manufacturer website;

Their ContactUs link is just a darn form though.

If you have the stuff I would rig it up and put a clamp on amp meter on it if amps go to hi slow it down.

Here's an ACD with a 1.5 HP........

Oddly enough, if you look close under the
spec plate it sez......1-ACD-9 :)

If that's the pump he has I am having a hard time believing its a 1 1/2 HP motor.. I took the bore and stroke and went to this site maybe that is correct...

Small update.

been busy all weekend at work, someone ran thru an electric gate at one of our construction sites, been dealing with that.

Still looking at info on that G-D pump, but believe it to be a 5hp need.

On another note, while continuing to clean the top of the loft, found a champion R5 pump. Found the specs on that... nice unit. 16.5cfm at 175 psi 140/175 on/off. it appears to pump well too.. so may go with that one. It for sure needs a 5hp motor.

Most of those mid range continuations duty pumps could be run with as little as a 3hp motor as long as the motor pulley was changed to a small pulley... You could also up the CFM with a larger motor and motor pulley.. You are only looking at 3/400 RPM with a 3hp/pulley combo motor, a extra 100 are so pulley/combo for a 5 will wake it up and supply you with a ell of a nice farm unit... It would supply all the air most would ever need...
 
Tell me about it.

Alredy got an 80g tank just waiting.

Did a hand test and that R5 is pumping.

I looke dup the specs, it can be driven up to 700 or so rpm.. not too shabby! Either of these should make a ton of air.

Now I just need to locate a single phase motor. i found a 3 phase 5hp job up in the loft. no idea where it came from.

like finding burried treasure with those pumps. even sandblasting should be easy.
