General Information
Fluid recommendations
Premium quality hydraulic mineral fluid is recommended, like HLP oils to DIN 51524 (part 2 & 3) or
ISO6743/4 (HM & HV). Brugger-value recommended to be
30 N/mm2 minimum for general application and 50 N/
mm2 for heily loaded hydraulic equipment and fast
cycling machines and/or high dynamic loads, measured
in accordance with DIN 51 347-2. See also Document
MSG30-3248/UK Parker Hydraulic Fluids.

Viscosity
The normal operating viscosity should range between
16 and 100 mm2/s (cSt). Max. start-up viscosity is
1000 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 (FKM shaft seal) -25…+ 90 °C
V – FKM (FKM shaft seal) -25…+115 °C
W – Nitrile (PTFE shaft seal) -30…+ 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.
