Hydraulic cylinders 350 bar series-production range

Liebherr presents its innovative series-production range of hydraulic cylinders, which offers highest flexibility for mobile and stationary applications. The pre-defined variants allow a quick adaption of the cylinders to every application and guarantee delivery.

LiView position transducer

The intelligent position transducer LiView determines the exact piston position and speed. The system is suitable for all hydraulic cylinders and convinces by easy mechanical integration. For safety-relevant applications, LiView is certified according to PL d and SIL2.

Technical Data Exhibit:

  • Max. measurement range: 10 m
  • Measured quantities: Absolute piston position and speed
  • Certification: PL d (EN ISO 13849) / SIL2 (EN IEC 61508)

Axial piston pump DPVO 215i

For high-pressure applications

The DPVO215i equipped with inverse piston technology boasts a wide swivel angle of 22 degrees, high pressure resistance and a 100 percent through-drive option. Additionally, it can be combined with all standard controllers, as used both in mobile and industrial hydraulics.

The built-in impeller reduces the risk of cavitation by prefeeding, allowing for a higher suction speed rating and enabling a greater flow volume.

Technical Data Exhibit:

  • Design: Variable displacement pump for open circulation
  • Nominal pressure / Max. pressure: 420 bar / 450 bar
  • Displacement volume: 216.6 cm3

Axial piston pump LH30VO

For medium pressure

The medium pressure pump LH30VO was especially developed for all mobile applications with open circulation. It complements the existing Liebherr portfolio of hydraulic pumps in the medium pressure range. The through-drive of up to 130% enables various applications in mobile hydraulics.
