Piston accumulator series-production range for 250 / 350 bar


You can choose from a range of combinational options within the piston accumulator series-production range. They are also flexible in terms of installation length.

We can also offer attachment parts on request.

Compliantly certified with standards

As standard practice, the piston accumulators are tested against the PED 2014/68/EU standards and rules and the ASME Code Section VIII in force.

We can also offer further certification on request.

Optimised service and maintenance plan

All our piston accumulators are designed to be particularly low-maintenance. In the event that you should require service however, Liebherr’s worldwide service network will be at your disposal at all times, everywhere.
