Eni Acer 32
Mineral circulating oil with anti-rust and antioxidant properties
ISO VG 32
The Mobil SHC 500 Series comprises exceptional performance hydraulic oils formulated from synthesised, wax-free hydrocarbon base fluids combined with a carefully engineered, super-stabilised additive system. They are exceptionally high-quality, wide-temperature, shear-stable hydraulic oils with controlled low-temperature pumpability and maximised anti-wear protection for high-pressure vane, piston and gear pumps, with very high viscosity indexes giving excellent performance at both low and high temperatures. The series exhibits outstanding shear stability for extended use in high-pressure, high-temperature operating environments without loss of critical lubrication characteristics, helping deliver long oil and filter life and optimum equipment protection that reduces maintenance and disposal costs. Developed with major OEMs for severe hydraulic systems using high-pressure, high-output pumps, close-clearance servo-valves and high-accuracy numerically controlled (NC) machine tools, the oils suit systems prone to deposit build-up, multi-metal component designs, cold start-up or very high operating temperatures, systems with unavoidable small amounts of water, and applications requiring high load-carrying capability and thin-film corrosion protection. The Mobil SHC 500 Series carries Denison HF-0, HF-1 and HF-2 approvals across its grades. It spans four ISO viscosity grades — 524 (ISO 32), 525 (ISO 46), 526 (ISO 68) and 527 (ISO 100) — with viscosity indices from 144 to 160, pour points down to -56°C, and flash points from 234°C to 243°C.
