Barnes Hydrolic pump ?

[Brushwacker]

? I bought this at an auction with some other stuff.It has a tag that says John S Barnes Corp
Rockford IL
4195
7 7 936 ( this bottom # has scratches and there could be more)
and on the low pressure side near the shaft it has this #
2670017
I would like to know if it is 2 stage and how many gpm it is rated.
Any help much appreciated.( I can't post a picture)

Barnes makes a very wide selection of pumps and the 2-stage pumps seldom have identifying numbers on them. The only numbers usually found are wholesalers product numbers rather than Barnes product numbers and these are on a sticker or metal tag.

Here is a Barnes site that may help identify the pump by using dimensions. Look under products then 2-stage or GC pumps. In the upper right corner, click for related documents.

I saved this from another pump thread. Check the dimensions.

The 2670017# is a casting number typical of all 4- bolt pumps.
