gpm vs displacement
gpm vs displacement
(OP)
I have a White HB series hydraulic motor with a displacement of 24.9 in^3/rev, flow rating of 20 gpm, and pressure rating of 2500 psi. Needed RPM is approx 200. I have been told that since I do not need the entire 24.9 in^3/rev of displacement to achieve the 200 rpm I need I can up the amount of flow higher than what is recommended. Is this true? If so, how much flow could I send through the motor? I would be interested in any formulas that relate RPM, GPM, and displacement.

RE: gpm vs displacement
The formula used is GPM = RPM x Displacement in gallons.
In this example I've used in³/min = RPM x Displacement in in³ then converted in³ to gallons.
