I. Product Overview
The Danfoss KRR/KRL series hydraulic pumps are high-performance axial piston pumps specifically designed for industrial hydraulic systems. Utilizing advanced piston-and-cylinder block designs, these pumps achieve oil suction and pressurization through the reciprocating motion of pistons within the cylinder block. With a focus on compact structure, lightweight design, high efficiency, and low noise, this series is widely applied in machine tools, injection molding machines, metallurgical equipment, construction machinery, and other fields, meeting the demands for high pressure, large flow rates, and precise flow regulation.
II. Core Performance Parameters
1. Operating Pressure
• Rated Pressure: Typically reaches 26–31 MPa, with some models capable of up to 38.5 MPa to accommodate high-pressure applications.
• Pressure Range: Broadly covers most industrial scenarios, ensuring stable system operation.
2. Displacement Range
• Offers multiple displacement options (e.g., 35–45 mL/rev) to suit varying flow requirements and system configurations.
3. Speed Range
• Generally operates between 500–2,880 rpm, depending on the model and application, supporting a wide range of operational speeds.
4. Volumetric Efficiency
• Designed for high volumetric efficiency, ensuring smooth operation and uniform flow output while minimizing energy loss.
5. Control Modes
• Supports multiple control methods, including pressure compensation and load-sensing, enabling precise flow regulation for complex operating conditions.
III. Technical Advantages
1. Compact Structure, Space-Saving Design
• Adopts an integrated design to reduce the number of components (e.g., integrated Gerotor charge pumps), minimizing volumetric losses and saving installation space.
2. High Efficiency and Energy Savings
• Leverages advanced hydraulic technology to enhance energy conversion efficiency and reduce power consumption, aligning with energy-saving and environmental trends.
3. High Reliability
• Utilizes high-quality materials and advanced manufacturing processes to ensure long-term stable operation under harsh conditions, reducing failure rates.
4. Strong Contamination Resistance
