Rexroth A10VSO18 Series 31 Axial Piston Pump
Open Circuit Hydraulic Applications
Overview
The A10VSO18 is a small-size axial piston variable pump used in open circuit hydraulic systems. It is typically applied in compact equipment where flow demand is not constant and installation space is limited.
Compared with fixed displacement pumps, it adjusts output according to system load, which helps reduce unnecessary power loss during partial load operation.
Compared with fixed displacement pumps, it adjusts output according to system load, which helps reduce unnecessary power loss during partial load operation.
Technical Characteristics
Pressure Range
Rated pressure around 280 bar, short-time peak up to 350 bar, suitable for light to medium hydraulic loads.
Flow Control
Swash plate design allows continuous displacement adjustment based on system demand.
Structure
Compact housing design makes it easier to install in small hydraulic power units.
Application Conditions
This pump is often used in systems where load changes frequently rather than running at constant full pressure. It performs better in equipment that requires responsive flow adjustment instead of continuous high-output operation.
Typical Equipment Applications
Industrial Machinery
CNC machine tools and small automation systems where hydraulic demand is moderate.
Processing Equipment
Injection molding machines and packaging equipment requiring stable but not heavy-duty flow.
Practical Advantages
• Works well under variable load conditions instead of fixed high load
• Reduces unnecessary energy consumption during partial operation
• Easier to integrate into compact hydraulic systems
• Suitable for equipment where space is a limiting factor
• Reduces unnecessary energy consumption during partial operation
• Easier to integrate into compact hydraulic systems
