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.
