10A Series Gear Oil Pump | 10A2X488 10A1.25X 10A4.2X | Micro Hydraulic Pump

LIC Hydraulic specializes in the 10A Series, a premier range of micro-sized gear oil pumps engineered for high-precision and high-pressure applications. Spanning displacements from 1.25cc to 4.2cc, the 10A series, including models 10A2X488 and 10A2X302B, offers the perfect balance of power and compactness. Built with high-tensile aluminum bodies and hardened gear sets, these pumps deliver consistent performance up to $250\text{ bar}$ ($3625\text{ PSI}$). They are the benchmark for mini hydraulic power packs (HPU) and specialized lubrication circuits.

Technical Specifications (Bulleted List)

• Frame Size: Group 1 / Micro Frame.

• Displacements: 1.25, 1.6, 2.0, 2.5, 3.15, 3.65, 4.2 ($\text{cc/rev}$).

• Max Pressure: Continuous $200\text{ bar}$, Peak up to $250\text{ bar}$.

• Speed Range: $500\text{ to }3500\text{ RPM}$.

• Efficiency: $\ge 90\%$ volumetric efficiency under rated conditions.

Key Technical Advantages

• Precision Powerhouse: Optimized for applications where space is at a premium but high pressure is non-negotiable.

• Pressure-Balanced Bushings: Floating bushings adjust automatically to maintain the seal against the gear faces, maximizing flow even as fluid temperatures rise.

• Reduced Noise Signature: Involute gear technology minimizes flow ripple and mechanical vibration, making it ideal for quiet indoor environments.

• Versatile Mounting (488/302B): Standardized flange and shaft configurations ensure easy integration into existing manifolds and motor couplers.

Application Areas

• CNC Machinery: Providing reliable lubrication and small-force hydraulic actuation.

• Mini HPUs: Used in dental chairs, lab lifts, and compact automotive shop equipment.

• Oil Transfer: Precise dosing or circulation in industrial cooling systems.

Expert Maintenance Tips

• Filtration Integrity: Due to the micro-clearances in the 10A series, maintain oil cleanliness at $ISO\text{ 19/17/14}$ to prevent premature wear.

• Alignment Check: Ensure the drive shaft and motor coupler are perfectly aligned. Even minor misalignment can cause radial stress, leading to shaft seal leakage.

• Temperature Monitoring: Small pumps have a higher surface area-to-volume ratio but less oil capacity; ensure your cooling system keeps the fluid below $60\text{°C}$ for optimal seal life.
