Bold dashed line:
Maximum speed
Bold solid line:
Rated speed
This pressure ensures that the cylinder block will be properly filled and that there is no pulling between piston and shaft.
The required pressure is 0 bar at 0 rpm and increases with rpm.
For open circuit applications it is not allowed to operate above rated speed. For closed circuit applications operating between rated
and max. speed, please contact your local Danfoss Power Solutions representative.
