Description
VP01 Axial Piston Pump For Lawn Mowers Hydraulic Drive Agricultural Pumps
VP01 Axial Piston Pump for Lawn Mowers
As the primary hydraulic power unit in lawn mowers, the VP01 axial piston pump delivers reliable performance for professional landscaping equipment.
Key Applications
  • Blade Drive System: Delivers high-pressure flow to rotating blades for efficient grass cutting with infinitely adjustable blade speed (20-500 ml/r displacement) via mechanical servo control.
  • Travel Drive: Powers hydraulic motors for wheels/tracks, enabling stepless speed control and enhanced slope climbing capability (>30% gradient).
  • Cutting Height Adjustment: Synchronizes with hydraulic cylinders to dynamically maintain blade height (5-15cm range).
