Core Features:

• Robust Swashplate Design: The proven swashplate design ensures reliable operation, excellent efficiency, and long service life in open circuit applications .

• Multiple Advanced Control Options: Wide variety of controls available (DR/DFR/DFR1/DFLR/ED) to suit specific application needs, allowing precise customization to various system requirements .

• Stepless Variable Displacement: Flow is proportional to drive speed and displacement, adjustable steplessly from maximum down to zero via the swashplate angle, offering precise flow matching to reduce energy consumption and heat generation .

• Excellent Suction Characteristics: Superior self-priming performance ensures reliable operation even in demanding conditions and at higher speeds .

• Through-Drive Capability: Universal through-drive design allows mounting of additional pumps up to the same nominal size for multi-circuit systems, enabling flexible and space-saving system configurations .

• Low Noise Operation: Optimized design with spherical porting ensures low noise levels during operation, contributing to a more comfortable working environment .

• Short Control Response Times: Controls with rapid response times ensure precise operations and better handling in dynamic system conditions .

• Durability: Robust bearing system and high-quality materials (cast iron construction) ensure long service life in demanding continuous operation . The drive shaft can withstand both axial and radial loads .

• Dual Case Drain Ports: Two case drain ports facilitate maintenance and fluid management within the hydraulic system .

• High Power-to-Weight Ratio: Compact construction delivers impressive power density in a lightweight package .
