Rexroth A10VNO Series Pump | A10VNO41, A10VNO45 | 52 Series Low Noise Piston Pump

Rexroth A10VNO Series (Series 52) Axial Piston Variable Pump

Product Overview: The Rexroth A10VNO series, built on the high-performance Series 52 platform, is an axial piston variable pump specifically engineered for open-circuit systems where noise reduction and power density are paramount. Compared to the standard A10VO series, the A10VNO minimizes fluid pulsation through optimized internal flow paths and swashplate supports. Whether featuring DFR1 Load Sensing control (e.g., A10VNO41) or DR Pressure Control (e.g., A10VNO45), these pumps ensure peak operational efficiency combined with exceptional smoothness.

Key Technical Advantages:

• Superior Series 52 Power Density: Features a more compact housing that delivers higher pressure ratings and displacement output within the same installation envelope, making it ideal for modern, miniaturized Hydraulic Power Units (HPU).

• Enhanced Low-Noise Operation: Specifically acoustically optimized for VNO specifications, significantly reducing mechanical noise at operating frequencies—perfect for indoor factories or urban construction machinery with strict environmental requirements.

• Intelligent Control Modulations (DFR1/DR):

  • The A10VNO41DFR1 integrates Load Sensing and pressure cut-off, ensuring pump output perfectly matches load demand and eliminating unnecessary overflow losses.

  • The A10VNO45DR provides classic pressure compensation, de-stroking once the preset system pressure is reached to maintain a constant pressure level.

• Robust Thru-Drive Capability (HRC40/VSC11): Includes superior thru-drive functionality. Specifications like HRC40N00 allow for tandem mounting of a secondary pump, facilitating compact multi-circuit power distribution.

• Specialized Customization (S1421): The S1421 customized version optimizes internal damping and response for specialized industrial applications, ensuring control precision and extended service life under grueling conditions.
