That's a Campbell Hausfeld TF series pump.
Yeah some guy on craigslist is selling it for $100 bucks...he said its a 2 stage compressor...so I go to ask him how many hp is the motor and he told me its on 2hp...that's what through me off...and the psi cut in @90psi and cuts off @120psi does that sound about right?
Is that a compressed panoramic picture? That's the funniest looking 60 gal tank I have seen.
Yeah I think its compressed picture I was thinking the same thing

There are some 60 gallon units out there that have short, fat tanks. This might be one of them.
Is it for home use? Don't be put off by an old 2Hp unit as they actually had an honest output at a low RPM which made them efficient and quiet. Just about all consumer grade compressors today are hugely overrated in the motor rating department and many make up for it with higher rotational speeds to boost their CFM. Assuming a sound tank and pump was never run low on oil I'd buy that over some bargain store "5Hp" unit no question. Pressures can be set on the switch, most tanks or pumps have a recommended limit. I doubt its less than 150PSI.
He said the max working psi is 200psi does that sound right?
Yes, and reinforces that its a 2 stage. Honestly you're not going to go far wrong for a working compressor at $100. You also wont need to run it at max pressure. Just about every air tool will run great with 100-120PSI at the line.

Love those short chubby 60 gallon tanks. For $100 you'll not go wrong at all. I'd be all over that if everything is in working condition.
Time how long the compressor takes to fill the tank from empty.
2 stage WILL give you chance to have higher pressure. However, I'd run the compressor just like it is for a while to ensure it's performance could handle the extra load of higher pressure.
OP . . . please tell us you're pulling the trigger on spending $100 to get it !!

with an air cleaner like that it would look cool with a flame job. I would buy it.

That's a 5hp pump being driven by a 2hp motor so don't get too ambitious before you figure out how many amps you are pulling. That does not look like the original pump to me.

Those are cool tanks and I owuldn't mind owning one like it; it's stable for sure. The advantage of having a 60gal shorty pump is handling the pump w/o reaching up and potentially kill yourself w/ the heavy cast iron pump. The pump is a CH 5hp style they still produce today.
a 3600rpm motor 5hp $200 will be your cheapest route. You might be able to find US made century motor 5HP on eBay for under $200.

I have a 5hp motor that spins @ 3440 rpm already....what's size outer diameter pulley you reccommend?
Trey T

I'm guessing 4" diameter. That'll spin your pump to about 1000rpm. Check the pump specs though.
I believe the pump speed is supposed to be 685 rpm
So with the pump speed is supposed to spin at 685 rpm and my 5hp motor spins at 3440 rpm......What size outer diameter motor pulley should I get?

Is it a true 5HP motor? If so, the Full Load Amps (FLA) on the data plate should be 22-25 amps at 240VAC.
If less than 20 amps, you've got an SPL motor that is probably about 3.3HP. If you try to run this HP motor at the pump's 5HP speed, it will probably work, but the motor will be severely overloaded once it gets above a certain pressure.
And on the pressure switch, it will be easier on the motor if you dial the range back to, say, 120-150psi. Yes, it will cycle on slightly more often vs. having it set at 145-175.
The specs on the motor says 18 amps

Depending upon the motor efficiency (which is not given for this motor), it is between 4 and 5HP. I'd err on the low side of that, in order to maximize the life of the motor. It is internally thermally protected, so if it gets too hot it should turn off (red button on the end of the motor?).
Yes there is a red button on the end of the motor

So with the motor I have what should I set me my pressure switch too?
Not quite that simple. You have to balance the pump speed, motor current, and pressure. If you go to advanced search and put compressor and my user name in you will find some posts where I explain this in more detail. I'm outta time this morning.

Surely this can't be . . . . there should be overpressure relief device that blows out if pump erroneously runs continuous.
Put up MORE PICTURES of what all is on your compressor so some GJ guru's can help you out.
Yes there isn't one installed on there

If it were me, I'd install a 175PSI relief valve on the tank, and then set the pressure switch off point below this. You may also want to hydrotest the tank or at least do an internal inspection - plenty to read about this on this site if you search.
Ok so I found the pressure relief valve it was on the regulator that was included but was not hooked up.....it says 200 psi....does that sound about right?

Yes. But it doesn't hurt to go lower.
Have you inspected the inside of the tank or hydrotested it yet?
