PLANUREX 3 Standard Series

The PLANUREX 3 Standard Series, developed by FLENDER, represents a new generation of high-power-density, multi-purpose premium planetary gear units, setting new benchmarks in quality, flexibility and operational reliability for industrial drives. As a fully standardized product portfolio, it balances power density, equipment availability and cost efficiency optimally, with global short delivery times and excellent cost-performance ratio.

Available in 10 sizes, the series covers a nominal torque range of 1.7MN·m to 5.45MN·m and a transmission ratio range of 26 to 112. Boasting 17.2% higher torque density than its predecessor, it achieves class-leading efficiency with a compact design, enabling space-saving deployment of high torque and large transmission ratios. All sizes can withstand overloads up to twice the nominal torque, ensuring stable operation even under discontinuous loads.

Featuring high modularity, it offers diverse options for application adaptation, including torque shaft support, reinforced bearings, oil cooling connections and low-temperature compatibility down to -40℃. Integrated into Siemens Integrated Drive Systems (IDS), it realizes seamless matching of motors, couplings and lubrication systems for efficient operation.

Widely applied in mining, cement and raw material extraction, it excels as a drive for roller presses and tube mill central drives. Optional smart sensors enable real-time condition monitoring, supporting predictive maintenance and boosting long-term operational stability.
