Hyd pump

TJ, flow in a hydraulic pump is the result of displacement and rpm.  Different pumps will have different maximum rpm so two pumps may have the same flow but at different rpm due to their construction. A heavy pump may cavitate if driven at 2500 rpm when a smaller lighter one may be ok at 4500 rpm.

When you read the specs of a pump you will see displacement in a unit of volume like cc or cubic inches, then Max speed for that pump, maximum flow at that particular maximum speed, and pressure. So there is no set RPM to rate all pumps unlike air compressors that can rate a compressor in CFM simply because they are driven by an electric motor that has a constant and known speed. 

Hydraulic pumps are rated at their maximum speed and that maximum speed is dependent from their construction.
