At this year's Hannover Messe, Liebherr's components division presents a range of product innovations in the fields of hydraulics and electronics: from innovative servo and industrial cylinders, through smart measurement technology to hydraulic pumps with inverse piston technology. With the component solutions on show, the Liebherr show team offers professional visitors a unique exhibition programme.

Displayed on the Liebherr stand will be the high-dynamic servo-cylinders, designed especially for applications requiring high speeds, precise control and the utmost reliability. This makes the cylinders ideal for use on test benches, in the tool industry and in forming operations. The servo-cylinders stand out in particular through their smooth-running and friction-optimised operation, as well as their service-life endurance. To achieve all this, Liebherr uses a single-piece piston rod in conjunction with a bronze-coated piston and specially-adapted seal systems.

With the cylinders of the ISO 6022 industrial series, Liebherr is expanding its existing product portfolio. The installation dimensions and fastenings of the series correspond to standard specifications, while selected details offer customers the highest degree of flexibility and individuality for every application. The differential cylinders can be optimally integrated in machine tools, automation and manufacturing technology solutions and in applications for the automotive and steel industries. Depending on requirements, they can be fitted with the LiView® position transducer, end position damping, proximity switches or pressure sensors, along with measurement connectors and ventilation.

In the field of hydraulics, Liebherr also presents to exhibition visitors its energy-efficient hydraulic power units, along with the series-production range for heavy-duty applications in the pressure range of up to 350 bar.

For the automation of cylinder movements, Liebherr also presents the newly-developed smart LiView® position transducer for hydraulic cylinders. This system was developed to determine the precise piston position and speed by means of high-definition absolute measurement. It is suitable for all cylinders, irrespective of length or diameter. For safety-relevant applications, LiView® is PL d and SIL2-certified. Thanks to its unique measurement concept, LiView® proves a winner through its rapid and easy mechanical integration.

In the field of axial piston hydraulics, too, Liebherr once again demonstrates its competences in presenting the new DPVO215i variable displacement pump, specially designed for open circuits. The hydraulic pump is equipped with inverse piston technology for high-pressure applications, and stands out with its wide swivel angle of 22 degrees, high pressure resistance and a 100 percent through-drive option. It can also be combined with all standard controllers, as used in both mobile and industrial hydraulics. In addition, the DPVO215i has an impeller, which reduces the risk of cavitation by prefeeding, allowing for a higher suction speed rating and enabling a greater flow volume.
