Sauer-Danfoss series S45 axial piston open circuit

PeRfoRmanCe
K45D
Flow and power data valid
at 49°C [120°F] and viscosity
of 17.8 mm²/sec [88 SUS].
The chart on the right
shows allowable inlet
pressure and speed at
various displacements.
Greater speeds and lower
inlet pressures are possible
at reduced displacement.
Operating outside of
acceptable limits reduces
pump life.
