    I recently picked up some splitter parts and equipment, and have a pump which I have been unable to identify. :eek:hh: It looks like it's a two-stage unit, and on the rear (non-drive) end of the pump is stamped "PR66", "Hi" & "Low". It has a standard 4-bolt flange with a 1/2" keyed drive shaft.

    The pump is on a small splitter that has a 20" stroke cylinder. It's funny because whoever built it must have used whatever he/she had laying around for parts, because they used a 1 3/4" cylinder. The thing works - the cylinder goes back and forth, and it's got great cycle times, but can't split hardly anything because it just doesn't make any force, before going over relief - what do you want out of such a small piston?

    I may just retrofit the cylinder with a larger one so it will perform and be useful for lighter duty stuff, but I want to find out what the pump actually is, first. Then I may be able to use this cylinder on the "Real" splitter I'm building for a log lift. If the stroke is too long for that it's no big deal, I'll just get the correct cylinder, but if it will work that's less I'll have to come up with for the new machine.

    I'll get some picks posted tonight if possible, but in the mean-time if anyone has a pump like this I would really appreciate knowing the GPM displacement and if it truly is a 2-stage pump.

    An easy way to tell is... if it has a 3/4" inlet port its a 11gpm pump and a 1" port is for a 16gpm pump. My guess is its 11.
