There's no gear reduction in the pump. The Motor has 353KV when taking 10 amps; the revs lowers for each more amp about 4KV.
The hydraulic power output (35 Bar at 2 L/min) is 117W. For the pump I calculated 50% efficiency, so it need round about 235W on the shaft.
Due to the pump size (0.6cm³/rev) there must be a torque of 0.67Nm to reach 35 Bar. Control calculation brings ~3350 revs.

Those pumps are used very often in models, it is small and an industrial one. Markus
