High performance flow sharing system LUDV for compact excavators

Introduction LUDV

Bosch Rexroth has been one of the first hydraulics suppliers to introduce a flow sharing system for compact excavators. The new LUDV fully exploits the excavator’s potential, enhances fine control and precision performance. With 20 years of experience, Bosch Rexroth has further developed the LUDV flow sharing system by combining the new RS12 control block, the successor of the SX12, with a redesigned version of the proven and tested A7VO variable displacement pump and a compact MCR motor. Tests with a 6.5-ton excavator show an initial output 10 percent higher than that of a comparable machine and 8 percent less fuel consumption.
