Life time recommendations
Linde high pressure units are designed for excellent reliability and long service life. The actual service life of a hydraulic unit is
determined by numerous factors. It can be extended significantly through proper maintenance of the hydraulic system and by using
high-quality hydraulic fluid.
Beneficial conditions for long service life
>> Speed lower continuous maximum speed
>> Operating pressure less than 300 bar Δp on average
>> Max. pressure only at reduced displacement
>> Viscosity 15 ... 30 cSt
>> Power continuous power or lower
>> Purity of fluid 18/16/13 in accordance with ISO 4406 or better
Adverse factors affecting service life
>> Speed between continuous maximum speed and
intermittent maximum speed
>> Operating pressure more than 300 bar Δp on average
>> Viscosity less than 10 cSt
>> Power continuous operation close to maximum power
>> Purity of fluid lower than 18/16/13 in accordance with ISO 4406
