Hydraulic pump CC to GPM
Hyd Pump GPM
** Please note that the gearing that drives the pump can have a lot of impact on the output (IE- the pump is not usually turning at a 1:1 ratio of the engine). This is only a general guide.
5cc per revolution = appx 3.5GPM
7cc per revolution = appx 4.8GPM
9cc per revolution = appx 8.2GPM
