Rexroth A10VO45 DFR1 Variable Pump | A10VO45DFR1/31R & ALA10VO45DFR1/52L | Axial Piston Pump

Rexroth A10VO 45 Series Axial Piston Variable Pump (DFR1 Control)

Product Overview: The Rexroth A10VO 45 series is one of the most preferred power components in open-circuit hydraulic systems, widely utilized in plastic processing machinery, metal forming equipment, and various medium-sized mobile machines. With its 45 cm³/rev displacement and exceptional energy-saving performance, this series has become a standard configuration for high-performance hydraulic power units. Whether the classic Series 31 (A10VO45/31R) or the optimized Series 52 (ALA10VO45/52L), these pumps ensure efficient and stable operation through load-sensing control.

Key Technical Advantages:

• Precise DFR1 Load-Sensing: Models like the A10VO45DFR1/31R-PSC62K01 are equipped with pressure and flow compensation logic. The pump delivers only the exact flow required by the load, effectively preventing excess throttling losses and significantly reducing system heat generation.

• Cross-Series Versatility: This page features both Series 31 standard versions and Series 52 with specialized function codes (e.g., ALA10VO45DFR1/52L-VWC62N00-S1038), catering to replacement needs ranging from legacy machine maintenance to modern automated production lines.

• Superior Suction & Longevity: The flow-optimized port plate design maintains excellent self-priming capabilities even at speeds up to 2600 rpm, effectively extending the service life of the piston assembly and bearings.

• Customized Configurations (S1038/VWC): For specific industrial applications, various shaft standards like VWC and specialized function codes like S1038 are provided, ensuring high-precision physical docking and functional matching with the drive end.

Specific Models & Technical Parameters: This range includes core configurations: A10VO45DFR1/31R-PSC62K01, ALA10VO45DFR1/52L-VWC62N00-S1038, and the full A10VO45DFR1 series. Key specifications: Displacement of 45 cm³/rev; rated operating pressure of 280 Bar; peak pressure of 350 Bar; support for Clockwise (R) or Counter-Clockwise (L) rotation; and standard SAE or ISO mounting patterns.
