Can anyone  Id this hydraulic pump or what it was used on? Any ideas what it could be used for? Not certain but probably 12 vdc.

Can you get a better picture of the stampings on the top?

Yeah I should have my bad. Over at the neighbors and free. Will go get it tomorrow & verify voltage. if you zoom in you can make out some of it. 

I'm thinkin make some kind of outside the box lift for a tractor with it.

Probablh 12v.

Solenoid turns on the pump when the lever is moved to one side but not the other (see the spring.)

I’d bet it was from a small dump bed truck with a single-acting cylinder. Lever one way turns on pump and lifts the bed. Lever the other way drains cylinder back to the reservoir.

I’ve seen many of those used as snowplow lift pumps, some had two valves if it was a power angle plow. Many were made by Monarch Hydraulics. I still have a newer version of that pump on the shelf.

I immediately thought of a snow plow Don.

Perhaps on a dump tractor build or a sxs dump box?

So it would need weight of some sort to lower. Might be a hurdle. 

Maybe a toggle switch to run then feed a spool valve to run a double acting cylinder?

Jeep for a plow lift

I have 2 of those bought at engine shows. Single action cylinder but a double can be used just leaving the rod side connection as a vent
