Hydraulic oil's importance to pumps equals blood's to the human heart. Improper or contaminated oil causes most hydraulic pump failures. Consider these factors when selecting hydraulic oil:

 

  • Viscosity grade: Choose appropriate viscosity (e.g., ISO VG 46) based on ambient temperature. Excessive viscosity increases startup resistance; insufficient viscosity impairs lubrication.

  • Oil quality: Select oil meeting manufacturer specifications; avoid cheap, low-quality alternatives.

  • Cleanliness: Hydraulic systems demand extremely clean oil—even new oil requires filtration before use.

  •  

  • Proper maintenance significantly extends hydraulic pump service life:

  • Regularly check oil levels: Maintain proper tank levels; low levels can cause pump cavitation damage.

  • Monitor oil temperature: Ideal operating temperature ranges between 40-60°C; higher temperatures accelerate oil degradation.

  • Listen for abnormal noises: Unusual sounds often signal impending failure, requiring prompt inspection.

  • Replace filters regularly: Change hydraulic oil filters per manufacturer recommendations to maintain oil cleanliness.

  • Inspect seals: Address external leaks immediately to prevent air entering the system.
