Product Description
LIC Hydraulic’s Rexroth ALA10VO140DRG/31R-VSD62K68-SO808 (Part No. R902505590) variable displacement axial piston pump and its high-performance Rotary Group are the gold standard for industrial fluid power. This $140\text{cc}$ unit is engineered for systems requiring precise remote pressure control and high volumetric efficiency. Our rotary groups include the cylinder block, pistons, valve plate, and set plate—all manufactured to 100% OEM specifications for drop-in interchangeability. Every unit undergoes 100% dynamic load and compensation testing to ensure laboratory-grade reliability in demanding manufacturing environments.
Technical Specifications
Model: ALA10VO140DRG/31R (Series 31)
Part Number: R902505590
Displacement: $140\text{ cm}^3\text{/rev}$
Control Type: DRG (Remote Pressure Compensator)
Nominal Pressure: $280\text{ bar}$ ($4000\text{ PSI}$)
Peak Pressure: $350\text{ bar}$ ($5100\text{ PSI}$)
Seals: FKM (Viton) for high-temperature resilience (Code V)
Key Technical Advantages
Micron-Precision Valve Plates: The critical interface between the block and valve plate is ground to sub-micron tolerances, ensuring minimal leakage and maximizing efficiency at peak pressures.
Reinforced Piston Assemblies: Piston slippers are designed with advanced lubrication channels to handle axial shocks, preventing the scoring common in high-duty cycle applications.
Superior Thermal Management: Equipped with high-grade FKM seals as standard, the R902505590 can operate continuously in fluid temperatures up to $120^\circ\text{C}$ without degradation.
Optimized Flow Dynamics: The internal geometry of the ALA10VO140 series is optimized to reduce fluid ripple and cavitation noise, improving overall system stability.
Expert Maintenance Tips
Case Drain Management: For the 140cc large displacement pump, ensure the case drain line is sized correctly to prevent internal pressure spikes that can damage the shaft seal.
Filtration Integrity: To protect the precision-ground surfaces of the rotary group, maintain oil cleanliness at ISO 4406 18/16/13 or better.
Initial Priming: Always fill the pump housing with clean hydraulic oil through the highest drain port before startup to avoid a “dry start” of the piston slippers.
