7. Operating & Maintenance Guidelines
-
Fluid Requirements:
-
Use clean hydraulic fluid with proper viscosity (20-400 cSt)
-
Maintain fluid temperature between 10-60°C (max 80°C intermittent)
-
Ensure proper filtration (10 μm absolute)
-
-
Installation:
-
Mount pump securely on rigid base to prevent vibration
-
Align drive shaft accurately (max misalignment 0.1 mm)
-
Use flexible coupling for power transmission
-
Ensure proper inlet line size and minimize suction line length
-
-
Start-Up:
-
Fill pump with hydraulic fluid before initial start
-
Prime pump to remove air from system
-
Start at low pressure and gradually increase to operating pressure
-
-
Maintenance:
-
Regularly check fluid level, temperature, and contamination
-
Replace cartridge kit at recommended intervals (typically 2000-3000 operating hours)
-
Inspect seals and gaskets for leaks during maintenance
-
Follow YUKEN recommended service procedures
-
