Liebherr further expands its axial piston portfolio and introduces a concept study

  • The Liebherr components product segment is expanding its axial piston portfolio by two hydraulic pumps with nine nominal sizes
  • As part of a concept study, Liebherr introduces a system solution of a parallel pump with an innovative control system

At this year's Bauma, Liebherr is presenting two new product developments in the field of axial piston hydraulics, along with a concept study of a parallel pump with an innovative control system.

Upon development of new hydraulic solutions, Liebherr focuses primarily on solution orientation and digitalisation, as well as the ever-growing challenges therein. The product portfolio of open circuit pumps will, therefore, be broadened by the nominal size of 550 and as a double pump by the nominal size of 1100 cm3, respectively. The LH30VO family will also be expanded by the nominal size of 100.

DPVO 550i – on the pulse of current affairs with new nominal sizes of open circuit pumps

The mining and industrial sectors, as well as maritime applications place increasing demands on the availability and longevity of machines and technology. In order to keep up, the components product segment at the site in Bulle (Switzerland) is expanding its product portfolio of open circuit pumps by the nominal size of 550, which can also be used as a double pump of 1100 cm3. "Like all pumps in this product family, the DPVO 550i is characterised by a particular robustness. In the view of digitalisation, this product is ready to incorporate various sensor technologies", explains Guillaume Bonnetot, General Manager Systems at Liebherr-Mining Equipment Colmar SAS. "We are looking forward to see Liebherr components in use on our own machines".

LH30VO100 – the newest member of the pump family

Modularity is the signature trait of the LH30VO family with nominal sizes of 28, 45 and 85. Liebherr is further pursuing this approach with the inclusion of the nominal size of 100 cm3. Among other things, the LH30VO100 consists of a modular system of eight controllers with a variety of combination options. The variable drive-through concept allows the selection and addition of further pumps, when installing them on the machine. In doing so, Liebherr-Components is fulfilling the growing demand for products with a high degree of flexibility. With all its nominal sizes, the entire LH30VO pump family offers a wide range of applications from mobile machinery and stationary hydraulics, for primary work functions to secondary applications, such as in fans, auxiliary drives or steering systems.

With a concept study on parallel pumps with innovative controls into the future

In the concept study of a compact parallel pump with an electro-hydraulic control (Electro Hydraulic Control (EHC)), Liebherr merges mechanical features with electronics. In addition to the possibility of different gear ratios, this parallel pump offers an ideal solution for machines with conceptually different drive speeds. With the flexibility of a software-based electro-hydraulic control, it is able to provide the oil volume flow in an optimised, efficient and highly dynamic fashion. "Accordingly, the concept creates a prerequisite for future application with condition monitoring of the component", explains Albert Bertschi, Sales Manager at Liebherr Machines Bulle SA.

With these additions to the product families and the presentation of the concept, Liebherr is up to par with current and future user requirements and takes an important step towards the digitalisation of its products. This will pave the way for new applications and industries.
