Running multiple machines off of one hydraulic pump

Climbing under the reloading table to switch hydraulic lines to run multiple hydraulic presses is a pain and having more than one pump seems to be a waste of money.
What is an easy, straightforward way of plumbing the hydraulic system so one pump can operate multiple presses?

Thanks

I run 6 machines with one pump and one hose. I put the hose comes up thru the back of the bench top. It has a female disconnect fitting. The machines are outfitted with male fittings. You can go to a hydraulic supply and get the hose made at any length you want. Each of my machines sit on on their own 1/2 sheet baking pan (bought from Dollar store). I just slide the one I want to use over, connect the hose and I am ready to go. I leave the Cylinder bleed hole open and wipe the oil off occasionally. It is never much. I have Mec 9000H's and they do not need to be bolted down.

Mine is along the same lines but I used black pipe and gas valves. Went to local hyd place and had lines made to go from the valves to the cylinders. All except the hoses can be bought at Lowes. A purge valve would be recommended at the end of the line at the last press. Then you can also put the pump away from you so you don't have to hear it. Spolars do run dual lines though so its a touch more involved for those.

Your limiting factor to run more machines is the ability of the pump to provide the amount of fluid needed at the pressure required. As a Firefighter we would manifold our rescue equipment to 1 pump that provided pressure all the time in a circuit and 1 piece of equip. would run at normal speed, add another and you lose a percentage of work speed,etc. BUT since the MEC only uses 1 hose, I assume the pump cycles on and off to actuate the loader, so it appears to me that you could not operate 2 loaders at the same time.

Yes and No,
If you don't mind both machines going up and down at the same time, yes it will work. You can't operate individually because there is only one valve.

I think they would run but slowly. Never tried it. I have by accident left one turned on before and they both went up and down though. No shells in one.
OK, I was thinking there would be some way to keep the manifold pressure high from the pump, but have individual inline operating valves for individual presses. Guess I was thinking too hard!!

But it would be awesome for a couple presses with well working auto hull and wad feeders!!! Just sit there and operate the pedal, and watch them work!!
