If the output on a pumphead is only 3/8 whats the point of larger pressure ports on the blocks like 3/4" and 1"

Remember there is another factor in this too. Not only is it how the fluid pressure gets to the cylinders, but also its how fast it gets back into the tank for the next pressure spike. It all comes down to fluid and line restriction and cavitation.

well it depends on who you ask..cavitation can be almost eliminated if you use the right oil..well basically no matter what people think or say the smallest fitting in your system is going to be basiclly be max flow.so people believe flow is the key and others like pressure i think the bigger is better idea is what is fueling this big debate on large fittings.to some extnet what makes hydraulic pressure is restriction but the goal is to get an even balance
between the two...my personal experience is that bigger isnt always better..ive seen it work and also not work.experiment with your set up no one can really give you solid answers on how to do it right unless the person saying does the job..


remember ::it doesnt take one thing to get ten more inches
but ten things to get an on


THE FAT MAN...
