General information Fluid recommendations

• Normal mineral oil

• Premium hydraulic fluid / HLP oil

• Synthetic hydraulic ester

• Fire resistant fluids, water based (HFC)

Note: Maximum system pressure reduced to 210 bar for water based fluids. Bearing manufacturer life time reduced to 25% by using water based fluids.

Viscosity

Min. viscosity for short periods: 10 mm²/s (cSt) Normal operating viscosity: 15...40 mm2/s (cSt)

Max. viscosity for short periods: 1000 mm2/s (cSt)

Filtration

For maximum pump supplier and system component functionability and life, the system should be protected from contamination by effective filtration.

Fluid cleanliness should be in accordance with ISO classification ISO 4406. The quality of filter elements should be in accordance with ISO standards.

PI HY11-2601UK.PMD RH

Recommendation for filtration

Class 21/18/14, according to ISO 4406

21 = 10000 to 20000 particle > 4um per ml fluid 18 = 1300 to 2500 particle > 6um per ml fluid 14 = 80 to 160 particle > 14um per ml fluid

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, single shaft sealing -40 ... +90 °C

D - Nitrile, double shaft seal -40 ... +90 °C

V - Fluorocarbon, single shaft seal -15 ... +150 °C T - Fluorocarbon, double shaft seal -15 ... +150 °C Note: The highest fluid temperature will be at the drain port of the pump, up to 20°C higher than in the reservoir.
