Delivery rates and characteristic curves
The indicated nominal delivery rates refer to the nominal output
multiplied by the speed 1400 or 2800 rpm. The actual delivery
rate changes with operating viscosity and back pressure and can be
found in the following characteristic curve diagrams. These diagrams
are based on viscosity data in the range between 20 and 1000
mm
2
/s in increments of 20, 140, 750, and 1000 mm
2
/s.
Each gerotor pump has a characteristic curve represented as a func-
tion of the delivery rate above the delivery pressure (back pressure).
It is important to note that temperature influences can render lubri-
cating and hydraulic oils extremely thin or viscous.
Please consult with SKF in advance if you will use lubricating and hy-
draulic oils with an operating viscosity outside the specified range.
