Linde HPR105 Series (02 Series) High-Pressure Load Sensing Piston Pump

Product Overview: The Linde HPR105 series is a high-performance swashplate variable displacement pump engineered specifically for open-circuit hydraulic systems. As a cornerstone of the 02 series, its 105 cm³/rev displacement offers a perfect equilibrium between power density and rapid response. Known for exceptional self-priming characteristics, featured models like the HPR105-02 (H2X254B01770) and the double pump configuration HPR105D-02R (HYX271E00649) are widely utilized in rotary drilling rigs, concrete pumps, and heavy-duty mobile machinery. Its primary advantage is the integrated Load Sensing (LS) control, which dynamically modulates flow based on actuator demand to significantly reduce energy waste.

Key Technical Advantages:

• Intelligent Load Sensing (LS): Delivers only the precise flow required by the system, effectively minimizing overflow losses and thermal generation.

• Ultra-High Pressure Reliability: Rated for continuous operation at 420 Bar (42 MPa) with peak cycles reaching 500 Bar. The reinforced swashplate design ensures high performance and stability under grueling load cycles.

• Double Pump Capability (HPR105D): The HPR105D tandem configuration provides two independent 105cc outputs from a single drive source, ideal for large-scale equipment requiring multi-circuit synchronization.

• Superior Self-Priming Performance: Maintains high suction efficiency even at elevated speeds, reducing the need for charge pumps and simplifying overall system architecture.

• Precision Industrial Configurations: * H2X254B01770 / H2X254M01841: These codes represent precise factory configurations for shaft ends, mounting flanges, and regulator slopes, ensuring seamless OEM-standard replacement.

• Low-Noise Operation: Optimized valve plate technology suppresses fluid pulsations, keeping the HPR105 at an industry-leading quiet level during high-pressure operation.
