Linde HPR-02 Series Heavy-Duty Self-Regulating Variable Pumps

Product Overview: The Linde HPR-02 Series is a global benchmark for power in high-pressure open-circuit hydraulic systems. As a swashplate-type axial piston variable displacement pump, this series offers a comprehensive displacement matrix from the compact 75cc (HPR75) to the heavy-duty 105cc (HPR105D) and 135cc (HPR135). Featured models like the HPR105D-02R 2565 H12 and HPR75-02R (Serial No. HYX253X00375) leverage Linde’s patented “Self-Regulating” technology. Capable of precise flow distribution at continuous pressures up to 420 Bar, the HPR-02 series is renowned for its high volumetric efficiency, superior noise suppression, and extended service life, making it the premier choice for large excavators, rotary drills, forestry machinery, and heavy industrial HPUs.

Key Technical Advantages:

• Precision Self-Regulating Control: Integrated pressure compensators and flow modulation ensure the pump delivers only the exact energy required, drastically reducing energy waste and minimizing system heat.

• Ultra-High Pressure Capability: Rated at 420 Bar (6000 PSI) continuous with peak capabilities up to 500 Bar, specifically engineered to withstand shock loads in heavy-duty operations.

• Tandem Pump Configurations: Double pump models like the HPR105D allow for multiple independent hydraulic circuits on a single drive shaft, optimizing installation space and simplifying system layout.

• Quiet Operational Profile: Optimized swashplate dampening and valve plate noise-suppression technologies effectively mitigate hydraulic pulsations at high pressures, ensuring smoother and quieter operation.

• Longevity & Reliability: Built with reinforced piston groups and heavy-duty bearings to ensure 24/7 stability in the harshest environments, significantly extending maintenance intervals.
