Product Description
LIC Hydraulic offers the Eaton Vickers 3923, 4623, 5423, 6423, and 7620 Series heavy-duty fixed displacement axial piston pumps and motors. These units are the backbone of high-pressure hydrostatic transmissions (HST), capable of operating at continuous pressures up to $420\text{ bar}$ ($6000\text{ PSI}$). With specific configurations such as the 6423-545 and 4623-115, our products provide a 100% dimensional and performance match for OEM requirements. Known for their ruggedness and high power-to-weight ratio, these fixed units are ideal for paving, rolling, and mining machinery worldwide.
Technical Specifications (Quick Reference)
Series Range: 39, 46, 54, 64, and 76 displacement frames.
Max Pressure: Continuous $350\text{ bar}$ ($5000\text{ PSI}$), Peak up to $420\text{ bar}$.
Design: Fixed displacement axial piston, swashplate or bent-axis configuration.
Interchangeability: Full support for Vickers/Eaton specific dash numbers (e.g., 3923-277, 6423-049).
Key Technical Advantages
Heavy-Duty Bearings: Equipped with oversized tapered roller bearings to handle significant radial and axial loads from drive shafts.
Optimized Valve Plate: Precision-engineered valve plates reduce fluid-borne noise and pressure ripples, maintaining high volumetric efficiency at high RPMs.
Simplified Reliability: As fixed displacement units, they contain fewer moving parts than variable units, offering increased uptime and resistance to fluid contamination.
Thermal Resilience: Designed to operate efficiently across a wide temperature range, essential for outdoor construction and mining environments.
Application Areas
Paving & Compaction: Primary drive motors for asphalt pavers and vibratory rollers.
Concrete Transit: Drum drive motors for concrete mixers (replacing or supplementing Eaton 46, 54, 64 series).
Off-Highway Vehicles: Final drive systems for skid steers and specialized agricultural harvesters.
Expert Maintenance Tips
Case Drain Management: Always connect the case drain line directly to the reservoir with minimal backpressure. Excessive case pressure will damage the shaft seal and may lead to internal mechanical failure.
Filtration Standard: Maintain fluid cleanliness to at least ISO 4406 18/16/13. Piston units are highly sensitive to hard particles which can score the cylinder block and piston shoes.
Loop Flushing: In closed-loop systems, ensure the charge pump provides sufficient cooling flow to the fixed motor to prevent overheating during continuous high-load cycles.
