Petronas Hydraulic HV 32
High viscosity index hydraulic oil for wide temperature variations
ISO VG 32
PETRONAS HYDRAULIC 32 belongs to the PETRONAS Hydraulic Series, a range of high performance anti-wear hydraulic fluids specially developed for a wide variety of mobile and industrial hydraulic equipment operating under normal to heavy duty conditions. It is formulated with high quality selected mineral base oils enhanced with advanced anti-wear, anti-oxidant, anti-rust and anti-foam additives, giving high anti-wear protection, smooth operation of the hydraulic system and up to 3x longer lasting performance compared with the minimum TOST (ASTM D943) requirements of ISO 11158 HM. The fluid is recommended for mobile and industrial hydraulic systems that demand a high quality anti-wear fluid. Conditionally it may also be used in circulation, splash, bath and ring oiling systems feeding lubricant to gears and bearings, subject to confirmation by the PETRONAS Technical Service Team or the OEM manual. Key benefits include low temperature protection at cold start, high wet and dry filterability, high thermal and oxidation stability enabling long oil drain intervals, high rust and corrosion protection, excellent water separability, fast air release and foam stability, and compatibility with most metal alloys, seals and elastomers. This ISO VG 32 grade has a typical viscosity of 32 cSt at 40°C and 5.4 cSt at 100°C, viscosity index 102, flash point 220°C and pour point -33°C, with a TOST life of 3,900 hours. It meets or exceeds DIN 51524 Part II HLP, ISO 11158 HM, ASTM D 6158 HM, Bosch Rexroth RD90220, Parker Denison HF-0/HF-1/HF-2, Eaton 03-401-2010, Fives Cincinnati P-68/P-69/P-70, SAE MS1004, SEB 181 222, US Steel 126/127/136 and GM LS-2.
ASTM D6158, type HM — antiwear hydraulic oil
The American standard for mineral hydraulic oils of type HM, that is, oils with antiwear additives. It is the ASTM counterpart of DIN 51524-2 HLP and ISO 11158 HM.
Hydraulic oil, type H HM (FDIS 2008) — ISO 11158
The international standard for mineral hydraulic fluids; class HM is the antiwear oil, the ISO counterpart of DIN 51524-2 HLP.
Bosch Rexroth RD 90220 — mineral hydraulic fluids
Bosch Rexroth's works standard for mineral hydraulic fluids in its own equipment: filterability, cleanliness and antiwear performance beyond DIN 51524.
Parker Denison HF-0 — hydraulic fluid, most severe level
The most severe level of the Denison hydraulic fluid specification: the oil must pass the wear test on both a vane pump and a piston pump, dry and in the presence of water. HF-0 subsumes HF-1 and HF-2.
Parker Denison HF-0, HF-1 and HF-2
The three Denison hydraulic fluid levels quoted together. An oil covering all three passes the vane pump and piston pump tests alike, including in the presence of water.
Hydraulic oil Part II HLP (2006) — DIN 51524
Part 2 of the German hydraulic fluid standard: HLP oils — mineral oils with oxidation, corrosion and antiwear additives. It is the most widely quoted reference in industrial hydraulics.
SAE MS1004 — brake fluid classification
The SAE classification standard for glycol brake fluids, grouping the DOT levels by boiling point and cold viscosity.
Eaton 03-401-2010 — hydraulic fluids
Eaton's hydraulic fluid specification for its own pumps and motors, which unified the former Vickers I-286-S and M-2950-S requirements.
SEB 181 222 — HLP hydraulic oil
A delivery condition for mineral HLP hydraulic oils to DIN 51524-2, used when supplying German industrial equipment.
Fives Cincinnati P-68, P-69 and P-70 — hydraulic oils
The three Fives Cincinnati approvals for machine tool hydraulic oils, one per viscosity grade: P-68 for ISO VG 32, P-70 for ISO VG 46 and P-69 for ISO VG 68.
U.S. Steel 126 — antiwear hydraulic oil
The steel industry specification for antiwear hydraulic oils: wear protection, oxidation stability and demulsibility in rolling mill systems, where water is always present.
AISE 127 — steel mill lubrication recommendations
The AISE — today AIST — standard collecting the lubrication recommendations for steel plant installations: oil types, viscosity grades and requirements per equipment group.
The 2004 issue of the GM LS-2 specification for extreme-pressure gear lubricants.
