PSM Series Hydraulic Vane Pump with Motor | PSM-PSAO-05-CR-J30 | 1.5kW Motor Group

The PSM Series Vane Pump Motor Group from LIC Hydraulic is a highly integrated power unit designed for efficiency and silence. Models like PSM-PSAO-05-CR-J30 and PSM-PSA0-07CR-J35F1 combine a high-performance vane pump with a precision 1.5kW motor. This “pump-motor” design eliminates alignment issues common with traditional couplings, significantly reducing vibration. We guarantee 100% mechanical interchangeability and perform 100% pressure stability, flow accuracy, and motor temperature rise tests on every unit.

Technical Specifications

• Motor Power: $1.5\text{ kW}$ ($2\text{ HP}$)

• Pump Type: High-performance fixed displacement vane pump

• Operating Pressure: Rated up to $70\text{–}140\text{ bar}$ (application dependent)

• Configuration: Integrated direct-drive (No external coupling)

• Interchangeability: Fully compatible with Taiwanese and Japanese standard units

Key Technical Advantages

• Ultra-Quiet Operation: The natural low-pulsation characteristic of vane pumps combined with direct-drive integration results in a whisper-quiet operating noise of $60\text{–}65\text{ dB(A)}$, ideal for factory environments.

• Compact Footprint: By eliminating the pump bracket and coupling guard, the overall length is shortened, allowing for easy installation in tight CNC machine compartments and small power units.

• High Volumetric Efficiency: The pressure-balanced internal design maintains over $95\%$ efficiency, minimizing energy loss and heat generation during continuous operation.

• Leak-Free Design: Precision alignment between the motor and pump shaft reduces radial stress on the shaft seal, significantly extending the service life and preventing hydraulic fluid leakage.

Application Areas

• CNC Machinery: Lubrication and secondary control for lathes, grinders, and milling machines.

• Footwear Production: Hydraulic systems for cutting and molding machines.

• Automated Production Lines: Small-scale HPU for fixture control and clamping.

• Woodworking Machinery: Compact power sources for hydraulic presses and feeders.

Expert Maintenance Tips

• Initial Priming: Always pre-fill the pump through the outlet port with clean hydraulic oil before the first power-on to prevent dry friction damage to the vanes and rotor.

• Rotational Direction: Verify the motor rotation (typically clockwise “R”) immediately after wiring. Incorrect rotation will cause immediate internal mechanical damage.

• Thermal Control: For a 1.5kW unit, especially in small reservoirs, ensure adequate ventilation or use an oil cooler. Keeping oil temperatures between $30\text{–}50\text{°C}$ is critical for seal longevity and fluid stability.
