Chevron unveils premium hydraulic oils
The new premium hydraulic oils feature improved oxidation and shear stability — versus conventional monogrades — which deliver robust protection to hydraulic pumps, Chevron says.
Clarity Synthetic Hydraulic Oil AW (ISO 32, 46, 68), which provides excellent performance in low temperature climate, is designed to give maximum protection to both mobile and stationary vane-, piston-, and gear-type hydraulic pumps in high-performance applications as well as in environmentally sensitive areas, Chevron says.
The oil has a high viscosity index to improve hydraulic response time and increase operating temperature range, Chevron says. In field trials, Clarity Synthetic Hydraulic Oil AW has proven to reduce fuel consumption by improving overall hydraulic pump efficiency by up to 8 percent. By improving pump efficiency, it also showed a potential gain of 5-25 percent increased productivity depending on usage environment, Chevron says.
Rando HDZ oils (ISO 15, 22, 32, 46, 68, 100), are antiwear hydraulic oils formulated with premium base oil technology to protect hydraulic pumps against wear, rust and corrosion, Chevron says. They are recommended for hydraulic or circulating oil systems, including marine on-deck machinery, hydraulic actuated loading bins, or equipment that require a wider operating temperature as compared to a single viscosity grade oil.
In laboratory efficiency testing, Chevron says, Rando HDZ oils provided up to 5 percent improvement in overall hydraulic pump efficiency when compared to a typical monograde hydraulic oil like Hydraulic Oil AW (a lower VI product with VI<105). The multiviscosity feature of Rando HD Premium Oil MV promotes even and continuous power transmission over a wide temperature range with a minimum of shudder.
“In today’s highly competitive markets, companies are looking at all opportunities to improve efficiency, and therefore the bottom line,” said Jeff Snyder, Industrial Brand Specialist, Chevron Lubricants in a Chevron press release. “Hydraulic performance is often overlooked in this quest, but the right hydraulic fluid can deliver impressive fuel economy and hydraulic system performance improvements. The improved efficiencies reduced fuel consumption and lowered lubricant purchase volumes of Chevron’s premium products provide additional benefits to our customers compared to conventional hydraulic fuels. ”
