Product Description
Rexroth A10VSO Series Industrial Axial Piston Variable Pump
Product Overview: The Rexroth A10VSO series is a cornerstone of global industrial hydraulic systems, widely utilized in machine tools, injection molding machinery, metalworking equipment, and various stationary hydraulic power units. As a swashplate variable pump, it is renowned for its high power-to-weight ratio and exceptional operational life. From the compact ALA10VSO18 to the high-output ALA10VSO100, this series provides precise power delivery through various control options (such as DR pressure control or DFLR combined control) at rated pressures up to 280 bar.
Key Technical Advantages:
Sophisticated Control Logic: Models like the ALA10VSO18DR/31R-VSC12N00-SO981 feature standard DR pressure compensation, automatically modulating displacement based on preset pressure. The ALA10VSO100-DFLR/31R-VPA12G10 variant utilizes DFLR control, integrating pressure, flow, and power limitation to optimize energy efficiency and protect the prime mover.
Low Noise Operation: Optimized swashplate and rotor designs ensure noise levels remain minimal even during continuous full-load operation—ideal for indoor factory environments with strict acoustic regulations.
Excellent Suction Characteristics: The optimized internal flow path provides superior self-priming capabilities, supporting higher drive speeds and preventing cavitation while reducing dependency on inlet pressure.
Customization Flexibility (SO/VSC): Featuring multiple seal arrangements and shaft standards (e.g., VSC12N or VPA12G), along with specific function codes like SO981, ensuring specialized compatibility and long-term stability in specific industrial applications.
Specific Models & Technical Parameters: This range includes core configurations: ALA10VSO18DR/31R-VSC12N00-SO981, ALA10VSO100-DFLR/31R-VPA12G10, and the full ALA10VSO18 series. Key specifications: Displacements from 18 cm³/rev to 100 cm³/rev; rated pressure of 28 MPa (280 Bar); peak pressure of 35 MPa (350 Bar); Clockwise (R) rotation; and standard ISO or SAE mounting flanges.
