Core Features:
Bent-Axis Design: The robust angled shaft and conical piston design ensure high starting torque, excellent efficiency (up to 92% volumetric efficiency), and resilience against shock loads. The drive shaft can withstand radial loads .
Wide Control Range: Displacement can be adjusted steplessly from maximum down to Vg min = 0, offering a broad operational speed range without needing a gearbox. This enables the motor to satisfy requirements for both high speed and high torque .
Multiple Control Options: Large variety of controls available (HD/HA/EL/DA/MO) to suit specific application needs, allowing customization to various system requirements .
High Power Density: Compact and lightweight construction delivers maximum power output in a minimal installation space, providing an excellent power-to-weight ratio .
Optional Integrated Valves: Compatible with optional flushing and boost pressure valves, or integrated/attached counterbalance valves for enhanced functionality and load control .
Durability: Engineered for long service life with robust bearings, good starting characteristics, and low inertia. Features a ball-contact distribution plate that automatically centers during rotation for high efficiency and low noise .
High-Speed Capability: Approved for very high-speed continuous operation due to advanced seal design around piston rings and cylinder block .
