Product Description

AA10VO Series Axial Piston Variable Pump (AA10VO28FE1/AA10VO71FE1/AA10VO100FE1/AA10VO140FE1, R910995227, AA10VO100FE1/31R-PSC12K07-SO712)
Product OverviewEngineered as a cost-effective, high-performance replacement for Rexroth AA10VO series pumps, this lineup includes AA10VO28FE1, AA10VO71FE1, AA10VO100FE1, AA10VO140FE1, the OE reference model R910995227, and the specialized configuration AA10VO100FE1/31R-PSC12K07-SO712. Designed for heavy-duty hydraulic systems, this axial piston variable pump delivers exceptional pressure stability, flow adjustability, and durability, making it ideal for construction, mining, agriculture, and industrial machinery that relies on Rexroth-compatible hydraulic setups.
Key Features
Direct Replacement for Rexroth AA10VO PumpsManufactured to match the exact dimensional, interface, and performance specifications of original Rexroth AA10VO series pumps, the AA10VO100FE1/31R-PSC12K07-SO712 (with OE number R910995227) is a seamless drop-in alternative. No modifications to mounting bases, hydraulic pipelines, or control systems are required, drastically reducing equipment downtime and maintenance costs for operators.
Precision Variable Displacement ControlEquipped with an advanced swashplate mechanism, the pump enables stepless adjustment of flow output to match real-time system demands. It switches smoothly between high-pressure low-flow and low-pressure high-flow modes, maximizing energy efficiency while ensuring consistent power delivery for both light-load positioning tasks and heavy-load lifting operations.
Wide Model Range for Versatile ApplicationsThe AA10VO FE1 series covers diverse flow and pressure requirements to suit different machinery types:

Compact models (AA10VO28FE1): Ideal for light-duty equipment such as small excavators, agricultural sprayers, and compact hydraulic presses.
Mid-range models (AA10VO71FE1, AA10VO100FE1): Perfect for medium-sized machinery including loaders, concrete mixers, and road rollers.
Heavy-duty model (AA10VO140FE1): Optimized for high-power systems in mining trucks, large cranes, and industrial metal-forming machines.

Robust Construction for Harsh EnvironmentsBuilt with high-strength cast iron housings, precision-machined piston assemblies, and hardened steel components, the pump withstands extreme operating pressures, temperature fluctuations, and abrasive working conditions (e.g., dusty construction sites, humid agricultural fields, and rugged mining environments). Its advanced sealing system prevents hydraulic fluid leakage and external debris ingress, ensuring long service life with minimal wear.
High Efficiency & Low Energy ConsumptionPrecision manufacturing processes minimize internal friction and volumetric loss, resulting in outstanding hydraulic efficiency. The pump’s optimized flow design reduces energy waste, lowering overall system operating costs while reducing heat generation to extend the lifespan of associated hydraulic components.
Application Scenarios
Construction machinery: Excavators, loaders, cranes, concrete pumps, road pavers
Mining equipment: Mining trucks, rock drills, conveyor systems, tunnel boring machines
Agricultural machinery: Harvesters, tractors, irrigation pumps, grain elevators
Industrial equipment: Hydraulic presses, injection molding machines, metal cutting machines, marine hydraulic systems
