I have a Gast vacuum pump with a small glass jar attached that has oil in it. I have not been using this pump yet - but want to. But I do not know what kind of oil to use in this small glass jar. Anyone know?

I also have another Gast vacuum pump with out the oil jar. Is it better to use the pump with the oil jar or the pump without?

Thanks
Hugh

Buy them Used? Oil jar on the outflow side? Oil-lubed pump?

Do not use the oil-lubed pump for woodturning. Even with a filter in the line some fine dust will make its way to the pump and if it is the oiled type, the dust and oil will mix to form an abrasive paste. It will also lead to vanes sticking in their guides. The oil type pump would be OK for vacuum veneering or other uses where there will not be any dust involved. The oil is similar to air tool oil, but if you go to the GAST web site, you can locate a dealer who can supply you with oil and other parts.

Hi Hugh you may be describing the pumps I presently use they are about fifteen years old and have been rebuilt three or four times (rebuild kit consists of front and rear motor bearings and four carbon veins) the small oil reservoir on the side is to lubricate the veins. After quite a bit of use they are still capabile of 26" of Hg.
Model-0522-v3-g314dx
1/4 hp 220vac@2.7amp 1725rpm
As for oil Gast part #AD220, you can also use detergent type automotive engine oils with classification SF or CC usally printed on the side of the container 30wt below100 degrees F and 20wt above 100 degrees F.

I knew you guys would have the info I was after.

Mark - purchased one used ($50) and the other I got for nothing. One is 1/4 hp and the other is 1/3 hp.

Barry - That is what it looks like. I did not check the model number but it looks the same.

Steve - I will check the web site and see what I can download.

Thanks everyone.
Hugh
