Mobilfluid 125

Extra High Performance Power Transmission Fluid

Mobilfluid 125 is an extra high performance power transmission fluid that is formulated for use in hydrodynamic gears and hydraulic systems typically found in railroad, marine, construction, and industrial applications. It is formulated using high performance basestocks and advanced additives to deliver the precise performance required to transfer power responsively. Mobilfluid 125 is engineered to withstand the stresses of heavy-duty, low and high speed applications in a wide range of severe operating environments.

Features and Benefits

The use of hydrodynamic gear systems and hydraulic control systems depends on high performance fluids to achieve consistent and responsive control and efficiency of the equipment. These systems operate under high pressures and temperatures that can cause deposits in control valves where precise control of torque converters and hydraulics takes place. The key benefits of Mobilfluid 125 include:

Features Advantages and Potential Benefits
Good wear protection Extended component life, increased productivity, and lower maintenance costs
Effective resistance to thermal degradation and oxidation Significant reduction in harmful lacquers, deposits, and sludge
Maintains power transfer and good control response
Extends oil service life
Good low temperature properties Easy start-up and responsive hydraulic control
Effective rust and corrosion protection including long stoppages in wet or humid ambient conditions Reduces wear with reliable equipment start-up and lower maintenance costs
Excellent air release properties eliminate foaming problems Delivers optimal hydraulic response and power transfer
Maintains fluid film for improved lubrication
Compatible with seals and gasket materials used in these systems Reduced fluid leakage, pressure losses, and contamination
