Linde HPR-02 Series Pump | HPR105D, HPR160D, HPR165D | 420 Bar High Pressure Piston Pump

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

Product Overview: The Linde HPR-02 series is a globally recognized benchmark for high-performance Open Circuit hydraulic systems. This series covers essential industrial and mobile displacements including 105cc (HPR105D), 160cc (HPR160D), and the robust 165cc (HPR165D). Engineered for the extreme load cycles of heavy machinery, HPR-02 pumps deliver precise power distribution under a continuous rated pressure of 420 Bar. With advanced self-regulating features and control options such as Load Sensing and Power Limiting, these pumps excel in large crawler machines, oil rigs, and heavy industrial presses, significantly optimizing fuel efficiency and maneuverability.

Key Technical Advantages:

• Extreme High-Pressure Reliability: Rated for an operating pressure of 420 Bar (42 MPa) with peak cycles reaching 500 Bar. Features reinforced rotating groups and hydrostatically balanced swashplate designs for extended life under grueling 24/7 duty cycles.

• Precise Control Logic (02R):

  • Load Sensing (LS): Real-time sensing of system load demand automatically adjusts flow output, effectively suppressing heat generation and minimizing energy waste.

  • Power Limiter: Ensures that pump power absorption stays within the prime mover’s maximum output, preventing engine stalls or motor overloads.

• Highly Integrated Double Pump (D Models): The “D” suffix indicates a double pump configuration, allowing two units to be driven from a single shaft, drastically saving installation space and streamlining drive train layouts.

• Low Noise & Low Pulsation: Optimized 21° swashplate technology and specialized valve plate noise-reduction treatments maintain exceptional quietness and smooth operation even at full pressure.

• Superior Suction Performance: High rated speeds and excellent fluid charging capabilities effectively prevent cavitation, extending the maintenance intervals of hydraulic components.
