I got the last one of these motors SC had based on the impressive torque numbers. Now I'm wondering how exactly to implement it?
15.1 CU IN HYDRAULIC MOTOR
New VON RUDEN model MLHPQ250C5A hydraulic motor. Cast iron housing.
SPECIFICATIONS ç–‹isp. 15.1 cu. in. / rev.
ç*†otor Type Gerotor
姫ressure:
2540 PSI cont.
2900 PSI int.
謬orque:
3360 in-lbs. cont.
5160 in-lbs. int.
百peed:
245 RPM cont.
306 RPM int.
彦low:
16 GPM cont.
20 GPM int.
ç´�otation Reversible
ç*†ount 4 bolt Square, 3.25" B.C.
百haft 1" diam. x 1-3/4" keyed
1/4" keyway
ç´�qd. Filtration 25 micron
姫orts 1/2" NPT
匹ase Drain SAE 4
百ize 6-3/4" x 3-1/2" x 4"
百hpg. 19 lbs.
My tractor only produces a little under 12 GPM, but the relief pressure is 2900psi. I know I won't likely see the 300 RPM, but was thinking if I limited the reduction to 5:1 or so I'd account for the spool diameter and would still end up with a 8,000# pulling force and 50 FPM line speed with a 4" drum. Is that close to accurate? I'm not positive I'm doing the math right to get there.
