Air Lubricator Question

[Buzzie8]

I am installing a new air lubricator on the air that supplies my ARO pumps. I replaced the regulator this past summer and when I replaced it I thought I could get away without using a lubricator. I bought this wash in June and I do not have any experience with a lubricator. I am assuming that I buy Pneumatic air tool oil and fill the bowl on the lubricator and make sure that is down stream from the air filter (Water seperator) on the regulator, correct? I am doing this because I noticed one of my air pumps leaking air, especially in colder temps. I talked to an Aro technician and he said to install a lubricator and possibly rebuild the air section of the pump. I noticed that I can make the air leak go away when I increase the PSI going to the pump but when I back it off it starts again after after I leave and come back. Any ideas greatly appreciated.

Obviously you are relatively new to the forum or you would know that ARO pumps have long since been relegated to the garbage bin for Flojets. They always leak something and are nearly impossible to get working reliably. They are also terrible about stalling and losing prime. Your equipment must be relatively old. I can't imagine any mfr. is installing those things as OE any more. You can spend a ton of money and several years trying to get them to work right and in several years you will have less money and Flojet pumps, I know...been there, done that.

One other note. On top of all of the money I spent attempting to get them to work correctly they also cost me two air compressors from losing prime and causing a continuos run, burning up the compressor pump.

Did this technician tell you exactly what kind of oil to use? The manual says you can use lubricated air but that it must be compatible with the seal materials, and I doubt normal compressor tool oil is.
