I know very little about hydraulics. This pump has very many connectors and also an actuator. I am confused as to what it may possibly do. The original cost is over $8,000.00. It looks to be in a pretty sharp condition.
thanks

It looks to me to be a hydrostatic drive pump, or in other words a variable displacement piston pump. What it was for, or what it could be used for now is any one's guess. Without knowing the specifics of the pump it is hard to know what can be done with it. It may take some serious horsepower to run it, or maybe not. Greg

I'll take a stab at it. The actuator engages the pump drive, so that the pump can be started and run remotely by electrics. That means the gear box is constantly in motion, not like a drive that can be disconnected, but more like a turbine engine gearbox. Perhaps this was for a GSE (ground support equipment) turbine engine? The pump is a two stage pump, with the first pump being a suction pump and the second stage being a pressure stage. Most pressure pumps don't suck very well and suction pumps can't pump up much pressure. The small hose fitting is a drain. I might be wrong because I can't figure out for sure which fitting does what. There is a low pressure inlet, which is the large blue hose fitting. The small hose fitting is a drain, most likely. Next, I don't think it's a hydraulic pump. I think it's an oil pump for engine or other machine lubrication. The first stage is the scavenge pump and the second is the pressure pump. If it were hydraulic the fittings would be stainless, not aluminum, and the hose fittings would be at least aluminum AN type fittings. Usable in civilian life? That's certainly possible. I guess it depends on what you do, what you need, and how good your imagination is.
I'd see if ebay finds it valuable. Put it in the turbine engine parts category. If the end use sticker has FAA/PMA on it somewhere, it has aviation applications.
I did a search on the NATO Stock Number (NSN): see link
It could be some kind drive/control unit for an antenna. What type I don't know.
Someone else can take a shot at it.
It looks like a pressure compensated Cessna I used to see on cement mixer truck trailer axle assemblies. Similar to this one.
Yes, that makes sense to me. The federal NSN information says as much, it is a piston pump with actuator.
Thank you. I will open up the actuator box to see if the motor is 400 Hz or 60 Hz.

Makes full sense to me. The first compartment is the gearbox, and a few lines could be pumping oil through that gearbox just for lubrication.
No idea.
So, this one kind of offers the best of both worlds, is that right.
Okay, I got it. If you want more pictures, I can take some.
Makes sense to me.
Thanks. I will put it on ebay, but I have not decided where or how to describe it. Thank you for yor input, I appreciate it.

Thank you!

Looking at
Thank you. I saved your post, it is very nice. It makes full sense to me. I will try to talk to its manufacturer if possible. It looks like a very cute piece.
iI took the actuator box apart and found out that there is a 12VDC motor with gears and a screw drive inside. It works, as I learned by applying 12V to the inputs. It spins and shifts the lever.
