3.3 Characteristic curves
Delivery flow and power (basic pump)
The diagrams illustrate the delivery flow/pressure (without
controller).
Drive power at max. swash plate angle and drive power at zero
stroke and 1500 rpm.
Drive power/pressure at zero stroke and 1500 rpm
Inlet pressure and self-suction speed
The diagrams show the inlet pressure/speed at the max. swash plate
angle and an oil viscosity of 75 mm
