FAQ
Q Hydraulic oil selection?
A
HLP mineral oil (standard, 35-46 cSt); HFC fire-resistant water-based (steel, foundry); HFDU fire-resistant ester (mining); HVLP high viscosity index (outdoor, wide temperature).
Q High vs low pressure?
A
Low < 70 bar (mobile lift); medium 70-210 bar (construction); high 210-420 bar (precision injection molding, CNC chucks); ultra-high > 700 bar (jacks, blast valves).
Q Three top failure causes?
A
Oil contamination (NAS 9 → 6 quintuples life), over-temperature (> 70°C halves life), air entrainment (cavitation destroys seals).
