Key Features
- Variable displacement high-pressure axial piston design
- Pressure cutoff (DR control) mechanism for energy efficiency
- Robust cast iron construction for durability
- Wide displacement range (28-140cc)
- Compatible with various control options (pressure cutoff, load sensing)
Troubleshooting Guide
Insufficient or No Oil Output
- Causes: Clogged oil filter, low oil level, air leakage, internal pump leakage, incorrect motor rotation
- Solutions: Clean/replace filter, check oil level, inspect seals, adjust motor phase sequence
Vibration and Noise Issues
- Mechanical causes: Misalignment, damaged coupling, bearing wear
- Hydraulic causes: Restricted inlet flow, high oil viscosity
- Solutions: Realign pump/motor, replace worn bearings, ensure proper oil viscosity
Pump Overheating
- Causes: Excessive friction, high-pressure leakage, restricted flow
- Solutions: Adjust component clearances, clean/replace filters, verify cooling system
Maintenance Guidelines
- Maintain oil temperature between 25-60°C
- Ensure oil cleanliness level ≥ 8
- Conduct comprehensive inspections every 6 months
- Check oil replenishment pump status after 3000 hours of operation
- Always prime pump before starting to prevent dry friction
Installation Note: Pump/motor shaft concentricity must be <0.05mm, with maximum suction height of 500mm. Always use original manufacturer seals and components for replacements.
Frequently Asked Questions
What are the key technical specifications?
- Displacement (Vg max): 71 cm³/rev
- Nominal Pressure: 280 bar
- Maximum Pressure: 350 bar
- Speed Range: Up to 2,200 rpm
- Flow Rate: 156 L/min (at nominal speed)
