Hydraulic Oil Hvi68 Blue 20Lt

DESCRIPTION:
Hydraulic HVI 68 is specialised premium hydraulic fluids which have been formulated to handle extremes of operating temperatures, pressures, power densities and fluid flow rates which are associated with very high horsepower hydraulic systems. The oils provide unique, long life operating service characteristics by a combination of anti-wear, detergent and very shear stable viscosity-improving additives with proven rust, oxidation, corrosion and foam inhibitors. Hi-Tec Hydraulic Fluids ensure excellent filterability with hydrolytic and demulsibility stability.
Hi-Tec Hydraulic Fluids are not normally recommended as a lubricant for compressors, circulating systems, bearings, general purpose lubrication and enclosed gears where extreme high-pressure load characteristics are not required. For these applications, use Hi-Tec Compressor Oils.
BENEFITS:
WEAR PREVENTION. The anti-wear additives in Hi-Tec Hydraulic Fluids ensure special protection where very high pressures, power densities and temperatures are inherently experienced with high horsepower hydraulic pumps operating at pressures up to 28,000 kPa (4000 psi). Thus this fluid allows hydraulic systems to give long, trouble-free service when operating with the increased horsepower, increased temperatures, reduced oil volume reservoirs and resultant reduced de-aeration times.
Hi-Tec Hydraulic Fluids possess excellent filterability even in the presence of moisture contamination where other lubricants may cause deposition products which plug filter systems (formed as a result of hydrolytic instability particularly with non-ferrous hydraulic components). This may lead to pump starvation and ultimately premature wear, cavitation and equipment failure.
Hi-Tec Hydraulic Fluids are multigrade oils which, unlike the more conventional fluids, have smaller viscosity changes with temperature variations. At very high operating temperatures experienced in high horsepower hydraulic systems this property results in improved full-bodied, wear reducing, lubricating films compared to the thinned-out fluidity of the more conventional hydraulic fluids. This special viscosity control property is maintained by the very high shear stable viscosity improver (VI) incorporated in Hi-Tec Hydraulic Fluids, where other lesser VI’s would shear down to less wear-protective thinned-out fluids and thus shorten the life of the hydraulic equipment.
The high aniline point of Hi-Tec Hydraulic Fluids ensures good compatibility with synthetic rubbers, giving extended life to seals. The powerful anti-oxidation inhibitors of Hi-Tec Hydraulic Fluids reduce oxidation so that degradation is inhibited, thereby reducing corrosion related problems of shortened hydraulic life, erratic control valve operation, filter plugging, down time and so on.
Hi-Tec Hydraulic Fluids have Multi-Metal compatibility with the ability to control wear and corrosion of copper and aluminium alloys used in high performance pumps. Corrosion inhibitors and metal passivators formulated in these fluids, in severe operating service, prevent corrosion of steels and the above more easily attacked metals. While formulated with a low zinc formula, it is NOT recommended for silver components used in Lucas PM pumps. For these products use the Hi-Tec ZF range of products.
Hi-Tec Hydraulic 68 meets or exceeds the requirements of:
Vickers I-286-S, M-2950-S AFNOR NFE 48-603 (HM, HV)
Hagglunds-Denison HF-0, HF-1, HF-2 AFNOR NFE 48-691 (wet)
Cincinnati Milacron P-68, P-69, P-70 SS155434
DIN 51524, Part 2 and 3 ISO 6743/4 (HM, HV)
The anti-foam additive in Hi-Tec Hydraulic Fluids ensures any entrained air will quickly separate from the fluids so that wear producing metal-to-metal contact is avoided.
