EXCELLENT!!! Thank you! What I have is a double acting pump and double acting cyl..which can't be used with pressure, I want the oil to flow back but just with gravity. I don't want to engage the notor , jyst open the solenoud. Does this make sense? Its a
Its an old pallet stacker lift that always used gravity down lever...but it has a hose fitting st the bottom and top of the cylinder. The old motors pump went on it and this is what I have to work with now. I just want gravity down :). Thanks to anyone with a y time for a tip or two!
If anyone is planning on doing this when i did this when i was fixing my liftgate it appears that the pump does not hold pressure and lets the fluid go back into the pump causing my liftgate to slowly go down over a few minutes. Bought a single acting pump and it fixed it. Maybe it was a bad pump but just wanted to warn anyone incase theyre having the same issue.
@@dannygilley5090 you possibly could as long as you put the return valve back into the tank, but I’m not really sure to my knowledge. I don’t think so.
Hello, I am a mechanic/fabricator.
I have watched many videos and I must say " you are spot on" the best video, informative and accurate.
thank you
I couldn't get this to work unless I put the blue and black on same terminal. Blue opens the valve up, soo not sure how you got that to work.
Yes bro nice video

Yes that makes complete, this should help you
How many amps does this pump need ?
Can u used the others side by using blue wire to engage the solenoid

There are two sides to the pump...
One side holds pressure and one side doesn't.
I have a single acting cylinder with two hoses
Can I still use a double acting pump?

What about the double lines my cylinder on has 1 . So do i cap off one of the ports on pump?
Can I convert a single acting to doble acting?
No as it won't have the additional circuit and hydraulic ports/lines needed for double acting.
i have a double acting pump and cylinder. i wonder if i could do the same to it. does your cylinder only have one hydraulic line gong to it?
It does
pump raises doesn't drop, I hear the solenoid click
