Mobil SHC 525 (55 Gal. Drum)
Mobil SHC 525 synthetic hydraulic oil provides superlative protection of equipment even in a wide range of temperatures, beyond the capabilities of mineral oil-based products. The superior anti-wear properties and exceptional film strength results in maximum equipment performance and fewer breakdowns. Mobil SHC 525 ensures oxidation resistance and keeps systems cleaner, saving on energy consumption and allowing for longer oil and filter change intervals. The controlled demulsibility of Mobil SHC 525 permits the oil to work well in systems contaminated with small amounts of water. Mobil SHC 525 meets the strict requirements of hydraulic systems using high-pressure, high-output pumps, plus the critical requirements of other hydraulic system components such as close clearance servo-valves and high-accuracy numerically controlled machine tools. Mobil SHC 525 offers outstanding wear protection for high-pressure vane, piston and gear pumps operating in a wide range of temperatures.
The Mobil SHC 500 Series hydraulic oils exhibit outstanding low and high temperature performance helping to provide an extra margin of equipment protection above and beyond the capabilities of comparable mineral oil-based products. Their excellent oxidation resistance allows extension of oil and filter change intervals while assuring exceptionally clean systems and trouble-free operation. Their high level of anti-wear properties and excellent film strength characteristics result in exceptional equipment performance that helps prevent unplanned equipment breakdowns, and maximize equipment uptime, which can enable potential improvements in production capacity. Their controlled demulsibility permits the oils to work well in systems contaminated with small amounts of water yet readily separate large amounts of water.
