I sure want to say it is a BeGe pump.....but it doesn't look like the style I'm familiar with....also BeGe was pretty good about having their name and serial/model numbers stamped on their units.
Problem is there is very little information available on BeGe pumps and equipment.
May be a later model when the company fell into the hands of Oliver.
In any event they are a pretty simple build and your leak source is most likely an internal drive shaft seal.
my first thought was that it looked like a begee pump but all I have ever worked on had their name cast in every piece.
Hey OM, sorry it's taking so long to get those copy's to you just bought scanner and I'm trying to set it up with my note book should have them to ya by the end of the week.
Ya that is a bee gee pump we have two of them they are relible high psi and gpm they have a aluminum tag that's why you can't find any markings.
ok I found the rivets where there was a tag, but no tag.
anyone have a parts break down?
These folks have almost everything related to hydraulics and seals.

just have to measure up what you have and look it up.
