Characteristic curves determin. at speed n = 1500 rpm
All values were measured with mineral oil at a viscosity
of 30 mm²/s and 50° C.
All characteristics shown are typical. They can deviate
by up to 5% of the shown values depending on production
tolerances of new pumps under certain conditions.
Please note: The values shown for drain and pilot oil
apply for quasi-static operation (constant operation
conditions).
During the pilot processes, significantly higher pilot oil
flows can take place in short-term and can exceed 20 l/
min in extreme cases. Therefore, it is absolutely
necessary to set up the drain line without restrictions
and as short as possible to avoid unacceptably high
pressure peaks in the pump body.
