General Information
Fluid recommendations
Premium quality hydraulic mineral fluid is recomended, like HLP oils to DIN 51524, part 2. Brugger- value has to be 30 N/ mm2 minimum for general application and 50 N/mm2 for heavily loaded hydraulic equipment and fast cycling machines and/or high dynamic loads, measured in accordance with
DIN 51 347-2. See also Document HY30-3248/UK Parker Hydraulic Fluids.
Viscosity
The normal operating viscosity should range between 16 and 100 mm2/s (cSt). Max. start-up viscosity is 800 mm2/s (cSt).
Filtration
For maximum pump and system component functionality and life, the system should be protected from contamination by
effective filtration. Fluid cleanliness should be in accordance with ISO classification ISO 4406:1999. The quality of filter elements should be in accordance with ISO standards. General hydraulic systems for satisfactory operation: Class 20/18/15, according to ISO 4406:1999 Recommended cleanliness for maximum component life and functionality: Class 18/16/13, according to ISO 4406:1999
Seals
Check hydraulic fluid specification for chemical resistance of seal material. Check temperature range of seal material and compare with max. system and ambient temperature. N - Nitrile -40 ... +90 °C
Note: The highest fluid temperature will be at the drain port of the pump, up to 25 °C higher than in the reservoir.
