• Maximum continuous pressure: 280 bar (4060 psi)
• Peak pressure: 350 bar (5075 psi)
• Nominal displacement: 28 cm³/rev (1.71 in³/rev)
• Recommended hydraulic oils: ISO VG 15-68 mineral-based or compatible synthetic fluids
• Cleanliness requirement: ISO 4406 18/16/13 or better

Causes:

• Excessive resistance in oil suction pipeline (clogged filter, low oil level, air leakage)
• Internal pump leakage (damaged distribution plate, poor sealing)
• Inclination angle too small
• Motor reversal

Solutions:

• Clean oil filter, maintain proper oil level, check pipeline seals
• Replace worn components (plungers, distribution plates)
• Adjust variable piston to increase inclination angle
• Correct motor phase sequence

Causes:

• Misalignment between pump and motor shafts
• Damaged bearings or variable head bearings
• Inadequate oil viscosity or flow restrictions

Solutions:

• Realign shafts, replace damaged couplings
• Replace worn bearings
• Select appropriate oil viscosity, ensure proper piping

• 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

• Pump/motor shaft concentricity < 0.05mm
• Maximum suction height: 500mm
• Use original manufacturer seals and wear components
