Hydraulic HVI products are 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 horse-power 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.
Hydraulic HVI product ensures excellent filterability with hydrolytic and demulsibility stability. Hydraulic HVI products 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.
WEAR PREVENTION. The anti-wear additives in Hydraulic HVI products 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). These oils allow 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. Hydraulic HVI products 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.
