What is this pump for?

Oh gosh one of my favorites!!!! Thank you.....

 

Max RPM 3600. Must be old if these newer engines went 3600 you’d be in deep doo doo.

 

Remove yourself from the game for that egregious violation!

 

“Over center” means that the pump is a variable displacement pump, so it will keep a continual pressure in the system even when there is no load (volume requirement.) I usually see them in hydrostatic drives, where you have a motor connected in series to a pump. I would also try to set up some sort of rpm limit switch so that the engine can’t make the pump go over 3600 rpm, which may be a heck of a math problem since I’m assuming you’re going to set this up to run off the flywheel. It honestly looks kind of small, most of the hydraulic kits I’ve seen use a saeur danfoss 60 series.
