Rexroth ALA10VO28 Series 31 Variable Axial Piston Pumps

Product Overview: The Rexroth ALA10VO28 is a highly versatile variable displacement piston pump within the proven Series 31 platform, specifically engineered for open-circuit mobile hydraulic applications. This series excels in optimizing power systems through advanced control modalities. Featured models include the ALA10VO28ED72/31L-VSC12N00P (Material No.: R902488269) with electronic proportional control and the classic ALA10VO28DFR1/31L-VSC11N00 (Material No.: R992001768) with load-sensing capabilities. With its precise 28cc displacement and compact housing, it is the ideal power source for excavator auxiliary circuits, small drilling rig travel drives, and agricultural machinery power systems.

Key Technical Advantages:

• Intelligent ED72 Electronic Proportional Control: The ED72 module enables direct displacement regulation via current signals, allowing seamless integration with vehicle electronic control units (ECU) for maximized efficiency and superior control precision.

• Precise DFR1 Load Sensing: The DFR1 controller detects load pressure variations and matches system flow demand automatically, minimizing energy waste, reducing heat generation, and extending component longevity.

• Rugged Series 31 Architecture: Reinforced for dynamic mobile environments, offering excellent suction characteristics and shock resistance for stable output at a rated pressure of 280 Bar.

• VSC Standardized Interfaces: Utilizing standard VSC11/VSC12 shaft and flange specifications ensures high interchangeability across various equipment platforms, reducing downtime and maintenance costs.

• Specialized Left-Hand Rotation (31L): Specifically designed for counter-clockwise (CCW) engine PTO outputs, catering to unique power layout requirements in specialized machinery.
