沉淀物积聚极其关键的液压系统，例如复杂的数控 (NC) 机械，特别是在使用紧公差伺服阀的应用 在泵及其他系统元件中采用多金属设计的系统 可能出现液压液和冷却剂之间交叉污染的应用 高压叶片、活塞和齿轮泵 经常工作在很高的运行温度下的系统 少量进水不可避免的场合 含有齿轮和轴承的系统 要求高承载能力和抗磨保护的系统 薄油膜防腐蚀保护较重要的应用，例如含有水分的系统 Extremely critical hydraulic systems for sediment accumulation, such as complex numerical control(NC) machinery, especially in the application of tight tolerance servo valves Multi-metallic design in pumps and other system components Application of possible cross-contamination between hydraulic fluids and coolants High pressure blades, pistons and gear pumps A system that often operates at very high operating temperatures A small amount of water. An inevitable occasion. A system containing gears and bearings Systems requiring high load capacity and anti-wear protection Thin oil film corrosion protection of more important applications, such as water-containing systems
