paint for compressor pump?

[shannonw]

What kind of paint are you guys using for the pump?

I picked up a mid 90's ir 2340 30t, it's that grey color. I thought i saw some rustoleum industrial grey at ace the other day, does that work ok with the heat of the pump?

Which works best spray or brush on the pump? I'm thinking brush may give a bit better coat...the existing is pretty thick.

Thanks!

I have bought a couple of old Quinceys. All caked with oil grease grime and shop paint from years of use. Its hard to kill one of those old compressors. I have a old Brenner that was made in 1958 and has been in use every day and is my favorite compressor. First of all I scrape all the crud I can off it, then spary it with a can of de greaser, clean it off with hot water. I let it dry and the buy a can of oven cleaner from the dollar store and spray it down a couple time with this then use hot water to clean it off. (watch out for fumes and wear googles) . Then I used Glidden industrial epoxy paint. Shop gray like the put on the floors. (my son works in a large factory and they use it on their floors)

Depending on Use and How Often, or Long that a Pump Cycles...They can get pretty Hot.
Also Oil or Oil Less Pumps.
I would use Spray Paint and Using Automotive Engine Paint is a High Heat Paint that would hold up extreemly well.
Color choices, may be the only issue.
Good Luck.

Yep, engine paint or other paint designed for at least 400F service would be my choice too.

I've measured over 300F on the air outlet from my compressor.
I'd probably go with black or some other dark color to help radiate the heat away.

Paint for grills/smoker may be something to look for. But I'd bet the engine paint from some place like summit or jegs will be the cheaper way to go.

If you are not concerned about color, then I would consider Hi-heat

BBQ and Grill spray paint by Rust-o-leum. Works well, looks fresh,

and the price is right. If you want a particular, but common color,

then take a look at automotive spray paint that is meant for use on

engines. Again, works well, looks fresh, but will cost you a bit more.

thanks for the input! Like that epoxy idea but i'd probably only do that if stripping it. yeah i may just spray with some VHT i've had good luck with that on outbboard valve covers. Pumps pretty clean just surface rust spots here and there from florida humidity. Probably use some enamel for the tank to freshen up...it's clean too just dusting of surface spots here and there.

It was the duplicolor ceramic engine paint i was thinking of, had a few cans left over and they look like they'll work. About the only thing you can get a decent color selection around here of high heat stuff (lots of colors at advance auto).

The tank i'm waffling but will prob go rustoleum in a quart, don't think i want to make a trip to the auto paint store and drag out the fresh air pump...not like it's out in the sun so imagine it will be ok. Any other suggestions for the tank?

For the pump I'm recommending high heat engine paint. NOT the stuff rated for 500F but the paint rated for 1000-2000F. I've used some 500F paint on hot surfaces and even at 300F, after a while the paint starts to bubble up and fall off. I painted my Quincy pump with 2000F black paint and haven't had any issues with the heat at all. I've measured the outlet temp at around 350F. I'm not familiar with the BBQ grill paint so I'm not sure of it's uses.
Another point to ponder, if you have multiple layers of paint, that isn't good. Paint will act as a thermal insulator. The thicker the layers of paint the hotter the pump will run because the heat can't get out. Not so much of a problem on your engine because it's liquid cooled, but a consideration for your air cooled air compressor pump.

This one was painted with regular oil based floor paint about fifteen years ago.....and is used regularly...to paint cars too!

Good point on the paint layers, i only plan on spraying a touch up coat not laying it on thick. Yeah i should probably do the 1200 but have a few cans of the 500 sitting around...i'll probably go on a limb and give those a shot. I noticed por has some as well at 20 bucks a quart.

I tried to stain wood with oil stain one time in florida, 1.5 weeks later it was like i just laid it on so i lean against oil based stuff. Water based stuff dries real well though..

Got most of the tank lightly sanded today, it's pretty clean but 15 years in florida humidity gets surface rust on anything. I probably wouldn't bother cleaning it up but it's in the middle of the garage bugging me (even though the garage is a continual mess) it stands out. Disassembled the motor to sand and paint it, the aluminum end caps were ugly from alum corrosion. It's a fast motor 3450 but a baldor, seems pretty well built and clean inside and runs good, has a fan on the back behind a casing and zerk fittings for the bearings so i examined those while i had the caps off.

I may look for the 1200+ ...looking again this would stink if it started flaking with all the cracks crevices and rough casting.
