Wet vac pump question

The typical "output" of these pumps
is a lot of air with a fair amount of oil entrained, almost like the
spray from an aerosol can.

I've tried 4 or 5 different units, and only the Airwolf did what it
was advertised to do.


I was afraid of that. Cheaper to go with a dry pump, I think.

Then you have no experience with a wet pump. Dry pumps are an absolute
joke. Owners rave about getting 500 hours out of one. I have a Garwin wet
pump on my 182. I give it exactly zero thought. No oil on the belly from
the pump either.

That's right, I don't. What I'm interested in right now is cutting down the oil
usage. It's not likely this plane will be used for IFR except possibly as a
trainer.

In that case, make sure you keep the old vacuum pump when you replace the pump with a
dry unit. You ought to be able to get a fair price for it.

Any wet pump that uses enough oil to be noticeable is in need of overhaul.

This is what I was wondering. I don't mind getting an overhauled pump if that
will stop it's oil usage, but the feedback on this thread leads me to believe
that many in this group think that 'noticable' quantities of oil out the wet
vac vent tube is normal. Do I have the wrong impression here (I hope)?

Yes, you have the wrong impression. After owning a Skylane for several
years, we had no issue with oil consumption due to the vacuum pump, but
did get enough oil on the belly to require an annual clean-up. However,
it takes very little oil to completely soil the bottom of an airplane.
Probably less than half a cup.
