Air cylinder operating on water pressure

Air cylinder operating on water pressure

I’m showing how I ran 100 PSI water pressure from a 12 volt pump to cycle a pneumatic air cylinder, This is a closed system with a small reservoir so the water can return and be pumped back through the system with out losing any fluid. The pump has a built in pressure switch so it automatically shuts off once it builds 100 PSI, this way it does not over work the pump and is more efficient.
I plan to use ether a light weight oil or a not toxic antifreeze in the future, this video was simply to prove a concept.
I’m posting this because I have not seen anyone running cylinders like this and wanted to share my idea with others.
This is the boom and bucket for a kids sandbox excavator I’m building for my son.
Thanks for watching!
