Fluid recommendations

Premium quality hydraulic mineral fluid is recommended,like HLP oils to DIN 51524, part 2.Brugger- valuerecommended to be 30 N/mm? minimum for generalapplication and 50 N/mm? for heavily loaded hydraulicequipment and fast cycling machines and/or highdynamic loads, measured in accordance with DlN 51347-2.

Viscosity

The normal operating viscosity should range between16 and 100 mm²/s (cSt).Max. start-up viscosity is1000 mm²/s (cSt).

Filtration

For maximum pump and system component functionality and life, the system should be protected fromcontamination by effective filtration.Fluid cleanliness should be in accordance with lSOclassification lS0 4406:1999.The quality of filterelements should be in accordance with lSO standardsGeneral hydraulic systems for satisfactory operation:Class 20/18/15, according to lS0 4406:1999

Recommended cleanliness for maximum componentlife and functionality: Class 18/16/13, according to lSO4406:1999

Seals

Check hydraulicfluidspecification forchemical resistanceof seal material.

Check temperature range of seal material and comparewith max.system and ambient temperature.

Note:

The highest fluid temperature will be at the drainport of the pump, up to 25 ‘C higher than in thereservoir.
