​

• Specifiion

• Key components

1.Precision Load Matching: The variable-displacement design ensures hydraulic flow/torque align with real-time task demands (e.g., more power for digging, less for idling), cutting fuel consumption by 15–20% compared to fixed-displacement pumps.

2.High Torque for Heavy Lifting: With a maximum output pressure of 40 MPa, it delivers enough hydraulic power to lift 10–15 ton loads (critical for 336D2/340D2’s rated digging capacity).

3.Durability in Harsh Conditions: The cast iron housing resists impact and vibration on job sites, while hardened pistons and Viton® seals withstand contamination and extreme temperatures—extending service life to 8,000–12,000 operating hours.

4.Smooth Operation: The swashplate’s gradual angle adjustment eliminates pressure spikes, ensuring jerk-free boom/arm movement and reducing operator fatigue.
