Valve screwing with my head

[muddstopper]

I am trying to do this on the cheap and still have something functional. Original plans was and might still be, to use stacked pumps with three sections, 60/30/15 gpm. this would keep everything on its own seperate power supply. I havent found a pump like this yet, but I have found what I thought was a two section pump, both sections providing 30gpm each. Turns out, this isnt the right sizes for this pump, one section is 3.86cuin and the other section 4.I forgot something cuin. Just found that out a little while ago. Still I can get the pump for just shipping cost, so I am trying to figure out how to make this work. I would still need another small pump for the other functions, but right now I am mainly trying to make the saw and splitter work, the rest shouldnt be a big problem. Depending on the engine rpms, the 3.8cuin section could power the saw, the larger section would run the splitter, it would just make it run a little faster. I believe my v70 valve should handle the combined flows since it is rated for up to 70gpm. I think with the efficiency losses, My valve should be ok. One possible problem is the pump is a CCW rotation. It may or may not be reversible and the person that owns the pump is going to take it apart to see if it can be reversed without having to buy a lot of parts. He knows it is possible to reverse the flow on this particular pump, but it may or may not require purchasing more parts to do so. Pump is in Minnesota, so i will just have to wait for him to find time to tear into it. I aint in a hurry so no problem there. I guess what I need to do now is assume the pump can be reversed and I can use it which would save me several dollars not having to buy a new pump. With that in mind, the only way I can find for this setup to work in any sort of acceptable manner is to run the small pump section thru the control valve for my saw and then combine the flows after to run the splitter. That way my saw will operate as if it is on a dedicated circuit getting full pump flow from section one of the pump and not be effected if i was trying to operate the splitter at the same time as sawing. All other functions for this processor will run off a different pump and wont be effected by saw or splitter operation. I guess I need to know the best way to combine the flows of the two sections.
