The difference between grease and engine oil is used for the suspension of centrifugal pumps ？

There are significant differences in composition, application and characteristics between the grease and engine oil used in the suspension of centrifugal pumps

Component differences

 grease is mainly composed of base oil and extreme pressure anti-wear additives, emphasizing anti-wear and rust prevention properties. It is suitable for low-speed and heavy-load rolling bearing. ‌

 engine oil ‌ contains components such as detergents and dispersants, antioxidants, etc. It is mainly used for internal lubrication of engines and needs to remain clean and reduce carbon deposits in high-temperature and high-pressure environments. ‌

Applicable scenarios

Grease is mostly used for lubricating the rolling bearings of low-power centrifugal pumps because it is easy to maintain and can prevent moisture from entering. ‌

Engine oil is specifically designed for lubricating and cleaning the internal components of engines, such as the lubrication between piston rings and cylinder walls. ‌

Performance characteristics

The viscosity of the grease is relatively low, making it suitable for stationary or low-speed rotating components.

Engine oil has a relatively high viscosity and needs to maintain its fluidity at high temperatures to form a stable oil film.
