Belt driven Hydraulic Pump, manufacturer and specs needed.

[the old grind]

There was a guy who was re-purposing a 6gpm or so OC setup. IIRC his res was 6-8 gal and fluid got hot w/o operating any cylinders.

Seems he'd added a pressure gauge between pump and stack, but plumbed it into 1/2" lines using a 3/8" tee. I never got over thinking he'd placed an unnecessary 'throttle' in a 'worst' possible place.

Gauge pressure seemed as expected, but that says nothing about flow beyond the narrow Tee. I'd expect a considerable amount of oil was going through the relief valve adding to the heat.

I don't recall reading if the hot hydro issue was ever overcome.

Looking at valve pictures I would estimate that casting to be 10 - 12 GPM but That is just a guess. A lot of older valves were in the 10 - 12 GPM range or larger. I don稚 recall seeing very many for lower flow. Part of this is due to running lower pressure 1250 - 1750 PSI range which requires larger cylinders that we see on systems today

Number of valve spools or sections also must be considered when sizing valves for pressure drop.

Good luck on this project

Thanks, leaning heavily towards making it a three-point mount and the tractor it would go on (L3830) has 8GPM available, so it being a 10-12gpm valve would be perfect.
