I. Product Overview
TheA10VSO45DR/32is a swashplate-type axial piston variable displacement pump from the REXROTH A10VSO series, specifically designed for open-circuit hydraulic systems. Constructed with cast iron, this pump features a compact design, high pressure capability, high efficiency, low noise levels, and flexible flow adjustment. It is widely used in construction machinery, industrial equipment, marine and offshore engineering, and other fields.
------
II. Technical Specifications
• Model: A10VSO45DR/32
• Type: Swashplate-type axial piston variable displacement pump
• Displacement: 45 cm³/rev
• Rated Pressure: 280 bar (some references mention a nominal pressure of 28 MPa; confirm based on actual operating conditions)
• Peak Pressure: 350 bar (some references mention a peak pressure of 35 MPa)
• Speed Range: Up to 2,600 r/min (specific speed depends on pump configuration and application scenario)
• Flow Range: Flow is proportional to drive speed and displacement; infinitely variable flow adjustment is achieved by adjusting the swashplate inclination.
• Control Modes: Supports multiple control methods, including pressure control (DR), remote pressure control (DRG), and pressure/flow control (DFR), to meet different operating requirements.
• Mounting Type: Flange-mounted, compliant with ISO standards or SAE metric thread standards.
• Weight: Approximately 21–33 kg (varies by configuration).
------
III. Performance Features
1. High Efficiency
• Advanced piston design and fluid dynamics optimization ensure higher efficiency during operation, reducing energy consumption.
• Hydrostatic unloading technology for swashplate bearings minimizes friction losses and improves mechanical efficiency.
2. High Reliability
• Rigorous quality control and durability testing ensure long-term stable operation under harsh conditions.
• Key components such as pistons, swashplates, and bearings are made of high-quality materials for excellent wear resistance and long service life.
3. Low Noise
• Optimized suction structure and case drain design reduce noise and vibration during pump operation.
• Advanced noise reduction technology ensures lower noise levels, providing a more comfortable working environment.
4. Flexible Flow Adjustment
• Infinitely variable flow adjustment is achieved by adjusting the swashplate inclination, meeting precise system flow control requirements.
• Supports multiple control modes for selection based on actual operating conditions.
5. Strong Adaptability
• Compatible with various hydraulic fluids, including mineral-based oils and biodegradable oils, to suit different application environments.
• Customizable configurations available upon request, such as built-in solenoid valves or low-pressure relief valves.
------
IV. Applications
TheA10VSO45DR/32hydraulic piston pump is widely used in the following fields:
• Construction Machinery: Excavators, cranes, road rollers, pavers, etc.
• Industrial Equipment: Hydraulic presses, injection molding machines, die-casting machines, extrusion presses, etc.
• Marine & Offshore Engineering: Deck machinery, steering gear, ship hydraulic systems, etc.
• Environmental & Energy Sectors: Wastewater treatment, garbage compaction, wind turbine hydraulic systems, etc.
------
V. Operation & Maintenance
1. Installation
• Ensure the pump is installed in a location that meets design requirements, avoiding excessive vibration and impact.
• Check that inlet and outlet oil lines are securely connected to prevent leaks.
• Select appropriate flanges and bolts based on the pump's mounting type to ensure secure and reliable installation.
2. Operation
• Before use, check the oil level and ensure the working medium is clean.
• After starting the pump, monitor its operating status closely; immediately stop and inspect if abnormalities such as excessive noise or vibration occur.
• Avoid prolonged operation under overload or no-load conditions to prevent damage to the pump or reduced service life.
3. Maintenance
• Regularly inspect the oil level, seals, and fasteners; replace worn components promptly.
• Replace filters and hydraulic oil according to usage conditions to maintain oil cleanliness.
• Perform comprehensive inspections and maintenance on the pump periodically, including cleaning the pump body and checking bearing wear.
4. Troubleshooting
• If the pump fails to start: Check power supply, motor condition, and whether inlet/outlet oil lines are blocked.
• If flow is insufficient: Check for secure inlet/outlet oil line connections and the presence of contaminants or foreign objects inside the pump.
• If noise is excessive: Check pump mounting security and for loose or damaged components.
