More efficiency, top performance and user-friendliness. These are the advantages of our perfectly matched hydraulic and electronic components for mobile and stationary drive systems. Electro-hydraulic, hydraulic or mechanical control. Whatever you choose, drive commands are precisely carried out on the spot. This makes your machine work responsively and efficiently.

All hydrostats of the Linde Series 02 have been designed for high power density. The increased piston stroke together with the optimized flow paths give increased efficiency of our rotating groups which transmit more power through smaller build size. Specific design features and unique material combinations assure a high wear resistance and long service life.

High transport speeds, constant working speeds or fast working and load cycles – these factors have an immediate effect on fuel consumption and noise emission. With the optimum use of the diesel power over the entire operating range we help you to increase the performance of your machine and to lower fuel consumption and noise emission.

Furthermore, our noise optimized hydraulic pumps for open and closed loop applications relieve the machine operators and the environment. Costly measures for additional noise dampening are reduced.
