Key Features
- Closed-Loop HST Architecture: Designed specifically for Hydrostatic Transmission systems, featuring a closed-loop circuit that allows for instantaneous direction changes and dynamic braking without mechanical wear.
- Dual-Path Independent Control: The assembly integrates two independent pump units within a single housing, allowing separate flow control for the left and right tracks. This enables smooth power turns and counter-rotation capabilities.
- High-Efficiency Rotating Group: Manufactured with premium-grade alloy steel pistons and precision-lapped valve plate to minimize volumetric loss, ensuring high torque retention even during prolonged dozing operations.
- Integrated Charge Pump: Includes a built-in charge pump that constantly replenishes the loop with cool, filtered oil, maintaining positive pressure to prevent cavitation and reduce system operating temperatures.
