The VP01 Axial Piston Pump is a high-performance hydraulic pump designed specifically for the blade drive systems in lawn mowers. This pump delivers high-pressure hydraulic flow to the rotating blades, enabling efficient grass cutting with infinitely adjustable blade speed (20-500 ml/r displacement) via a mechanical servo control. Ideal for professional landscaping equipment, the VP01 pump optimizes the performance of lawn mowers, providing excellent cutting results and energy efficiency.
Blade Drive System: Delivers high-pressure hydraulic flow to rotating blades for efficient grass cutting with infinitely adjustable blade speed.
Lawn Mowers: Specifically designed for use in the blade drive system of various commercial and residential lawn mowers.
Grass Cutting Efficiency: Supports adjustable blade speeds, ensuring consistent grass cutting performance across different grass types and conditions.
Infinitely Adjustable Blade Speed: The VP01 pump provides an adjustable displacement range (20-500 ml/r), allowing precise control of the blade speed to match cutting conditions.
High Efficiency: Delivers consistent high-pressure flow for optimized cutting performance while reducing fuel consumption.
Space-Saving Design: The pump's compact, modular design saves valuable space and integrates seamlessly with mainstream mower engines.
Energy Savings: Reduces fuel consumption by 12%-18% through automatic displacement reduction during idle periods.
Enhanced Durability: Built to withstand harsh outdoor conditions, the pump is designed for long-lasting reliability and low maintenance.
Pollution Resistance: Features enhanced seals and filtration compatibility, meeting ISO 4406 19/16 standards to extend service life.
