Manufacturer's description

Mobilarma 500 Series is a range of premium performance oils intended primarily as run-in or lay-up lubricants, providing effective rust-preventive films on the internal surfaces of machinery, and particularly suited as run-in lubricants for diesel and gasoline engines. The oils displace water from metal surfaces and form strong, water-resistant films to prevent rust and corrosion; any water present in the system is absorbed into a water-in-oil emulsion so contact surfaces continue to receive satisfactory lubrication. High chemical stability together with anti-wear and detergent properties make them suitable as high-quality short-term lubricants. In most applications the residual rust-preventive film does not need to be flushed away before the equipment is filled with service lubricant and returned to operation, simplifying lay-up and start-up procedures. Flushing is recommended only in specific cases — for example where Mobilarma cannot meet the operating loads and temperatures required, where drainage is difficult, where contamination could impair system oil performance, or where residual rust-preventive agents would reduce water-separation ability in turbines and similar equipment. Typical uses include run-in and lay-up oil for engines and industrial equipment, turbines out of service for extended periods, hydraulic systems where emulsion formation will not affect operation, and test/calibration oil. The series is offered in two viscosities (Mobilarma 522 and 524), with kinematic viscosities of 28.8 and 88.4 cSt at 40°C respectively, viscosity index of 95, pour points of -24°C and -18°C, and flash points of 182°C and 218°C.

Applications

• Run-in and lay-up oil for engines and industrial equipment
• Turbines that will be out of service for long periods
• Hydraulic systems where water is present and emulsion formation will not affect operation
• Test and calibration oil

Performance & benefits

• Excellent rust and corrosion protection, reducing clean-up time when returning equipment to production
• Displaces water from metal surfaces to form tenacious protective films
• Effective anti-wear properties, protecting equipment against wear
• Dual-purpose lubricant/rust-preventive nature, reducing the cost and time needed for run-in, testing or adjustment procedures and eliminating unnecessary flushing and draining steps

Fits

• Turbines & generators
