The VP01 Axial Piston Pump is designed specifically for cutting height adjustment in lawn mowers. It synchronizes with hydraulic cylinders to dynamically adjust the blade height within a 5-15 cm range, ensuring uniform and precise cutting performance. With its robust and efficient design, the VP01 pump ensures that the cutting height remains consistent, even in varying terrain or under heavy load conditions.
Cutting Height Adjustment: The primary application of the VP01 pump is for dynamic blade height adjustment, offering seamless synchronization with hydraulic cylinders to maintain a consistent cutting height (5-15 cm) for uniform grass cutting.
Lawn Mowers: Ideal for use in professional lawn mowers and landscaping equipment, ensuring the blades adjust automatically based on the terrain.
Hydraulic Systems in Landscaping Equipment: Can be used in other landscaping machinery where dynamic height adjustments are required.
Precise Cutting Height: The VP01 pump provides fine control over the cutting height, ensuring even grass cutting regardless of uneven terrain.
Durable and Efficient: Built with high-quality materials, the pump is durable and performs efficiently under demanding conditions.
Compact Design: Its compact size allows for easy integration into modern lawn mowers and landscaping machines, saving space and improving functionality.
Improved Fuel Efficiency: By offering precise control over the pump’s displacement, it helps to reduce energy consumption and extend the machine's overall life.
Pollution Resistance: Enhanced seals and filtration meet the ISO 4406 19/16 standard, preventing contaminants from affecting pump performance.

Material Selection: High-strength steel and cast iron are selected to ensure long-lasting durability.
Precision Machining: Key components undergo CNC machining to ensure exact tolerances.
Heat Treatment: Parts are heat-treated for enhanced wear resistance and longevity.
Sealing and Testing: All pumps undergo sealing tests to ensure leak-free operation under pressure.
Painting and Coating: A protective polyurethane resin coating is applied to enhance corrosion resistance.
Pre-Installation: Check the pump’s compatibility with the hydraulic system and ensure the correct fluid (46# hydraulic oil) is used.
Start-Up: During startup, ensure the pump is filled with clean oil to avoid dry running. Adjust the displacement for desired cutting height.
Maintenance: Regularly monitor fluid levels and check for signs of contamination in the hydraulic oil. Replace filters as needed.
Safety: Operate within the specified pressure and temperature limits to avoid damaging the pump.
Warranty: 12-month warranty on all products, covering manufacturing defects.
Technical Support: Full support for installation, troubleshooting, and maintenance guidance.
Spare Parts: Genuine spare parts available to ensure the longevity of your pump.
Global Service: Localized service in multiple regions for convenience.
Q1: Can the VP01 pump be used for other lawn equipment beyond mowers?
A1: Yes, it can also be used in other landscaping machinery that requires dynamic height adjustment systems, such as hedge trimmers or turf maintenance equipment.
Q2: How do I adjust the cutting height using this pump?
A2: The VP01 pump synchronizes with hydraulic cylinders to adjust the height within the 5-15 cm range, providing consistent cutting on varying terrains.
Q3: What hydraulic oil is recommended for the VP01 pump?
A3: We recommend using 46# hydraulic oil, which is optimal for the pump's operating range.
