HPR-02

Main advantages and scope of application of Linde HPR-02 series hydraulic pumps

The Linde HPR-02 hydraulic pump is a new generation of variable displacient axial piston pumps with a slant block for open hydraulic circuits, combining high energy efficiency, intelligent control and compact design. It is an improved version of the HPR-01 series with a number of significant engineering updates.

Main advantages of Linde HPR-02 series hydraulic pumps:

1. Increased energy efficiency
   • Reduced internal losses — up to 5–10% fuel savings compared to HPR-01.
   • Improved geometry of the piston group and distribution systi.
   • Lower oil heating tiperature = less cooling load.
2. Reliable operation under high pressure
   • Working pressure up to 420 bar, peak pressure up to 450 bar.
   • Increased resource when working with maximum loads.
3. Modular design
   • Single, double or triple housing options are available.
   • Easy integration into complex hydraulic circuits.
4. Modern electronic control
   • Full support for EDC, EP, LRC, CAN-Bus.
   • Ideal for integration into intelligent machinery control systis (Smart Hydraulics, GPS navigation, automation).
5. Extriely compact and lightweight design
   • 15–20% smaller dimensions compared to HPR-01.
   • Conveniently mounted in hard-to-reach places of mobile equipment.
6. Quiet operation
   • Reduced vibrations and acoustic noise - ideal for equipment operating in urban environments or near people.

Areas of application of Linde HPR-02 hydraulics:

• Modern construction equipment (excavators, loaders, graders)
• Agricultural machinery
• Municipal equipment
• Forestry machines
• All mobile machines with open hydraulic systis
