According to my Vivolo PDF file
the torque needed to reach 200 bar on a pump with volume of
1.5CC= 6Nm
3 CC= 12Nm
6 CC= 18Nm

A bosch 750 can drive a 1.5CC pump.
Will run at +/- 1700 rpm then at 24V at 200 bar.
This gives you 2.55 Liter flow a minute.

For a 3 or 6 CC pump youll need a bigger motor, or else a motor with a reduction gearing.
