Linde HPR-02 Series High-Pressure Open Circuit Variable Piston Pumps

Product Overview: The Linde HPR-02 series represents the pinnacle of high-pressure axial piston pumps designed specifically for open-circuit systems. Renowned for its superior self-priming capabilities and extended service life, this series covers displacements from the mid-range 75cc (HPR75) to the heavy-duty 165cc (HPR165). Flagship models include the HPR105-02R-2683 and HPR160/130DRN23MXXXXS. With its compact swashplate design, the HPR series delivers exceptional power density and precise flow modulation under extreme loads, making it the premier choice for rotary drilling rig power heads, heavy excavators, material handling cranes, and forestry machinery.

Key Technical Advantages:

• Superior Self-Priming: Optimized valve plate designs allow the pump to maintain excellent volumetric efficiency at high rotational speeds without the need for an additional charge pump.

• Extreme Pressure Durability: Rated for continuous operation at 420 Bar, with peak capabilities up to 500 Bar, engineered to handle the intense instantaneous shock loads of heavy construction equipment.

• Refined Control Modalities: Supports DR (Pressure Control) and LP (Load Sensing with Power Control), ensuring maximum energy efficiency and reduced engine fuel consumption.

• Low Noise Engineering: Features specialized sound-dampening housing and balanced rotating groups, maintaining low decibel levels even under high-pressure operations.

• Highly Compact Architecture: Integrated design supports versatile through-drive options, facilitating the mounting of tandem pumps or auxiliary gear pumps.
