• Rated Pressure: 400 bar
• Peak Pressure: 450 bar
• System Type: Closed-loop system
• Volumetric Efficiency: > 95%
• Application Field: Used in engineering machinery, agricultural machinery, mining machinery, and used in closed systems to provide hydraulic energy for rotating parts, etc.
Features:
• Axial piston pump with swashplate design for hydrostatic drives in closed circuits.
• Flow rate is proportional to drive speed and displacement, and is infinitely variable.
• Output flow increases as the swashplate angle moves from zero to its maximum position.
• Flow direction changes smoothly when the swashplate is moved through the neutral position.
• High-pressure, high-performance pumps perfectly suited for industrial and engineering machinery.
• Excellent oil suction performance and low noise levels.
• Long service life due to its robust and modular design.
• Fast response times and optional variable speed through-shaft drive.
• Equipped with a visual slewing angle indicator.
Application Scope
Suitable for closed hydraulic systems of construction machinery, agricultural machinery and mining machinery. It provides stable hydraulic energy for various rotating components of mobile equipment.
