Linde HPR-02 Series High-Pressure Self-Regulating Variable Pump

Product Overview: The Linde HPR-02 series represents the global standard for high-pressure axial piston variable displacement pumps in open-circuit systems. As the power core for premium mobile machinery, it is renowned for its superior Load Sensing and power-limiting capabilities. Featured models like the HPR105-02R (Part No: H2X254W01905, Serials: 2694 / 2681) are widely utilized in excavators, rotary drilling rigs, forestry equipment, and heavy-duty industrial presses. Linde’s signature swashplate technology delivers exceptional power density and millisecond-level displacement response, significantly optimizing fuel economy across the entire machine.

Key Technical Advantages:

• Precision Self-Regulating Load Sensing: The integrated regulator automatically senses system demand, ensuring the pump only outputs the required flow, eliminating excess heat and protecting system components.

• High-Pressure Durability: Engineered for continuous operation at 420 Bar (up to 500 Bar peak), utilizing Linde-patented wear-resistant alloys for all critical rotating groups.

• Superior Self-Priming Performance: The HPR-02 series maintains exceptional suction characteristics even at high speeds or in low-temperature environments, extending total service life.

• 100% Serial Number Precision: Manufactured to strict Linde official codes (e.g., H2X254W01905), ensuring mounting positions, splines, and control interfaces match original systems perfectly.

• Compact & Through-Drive Ready: Features a compact housing design that supports tandem mounting for auxiliary pumps, enhancing hydraulic system integration efficiency.
