Vickers PVXS Series Piston Pump | PVXS-130M04R | PVXS066 PVXS250

LIC Hydraulic provides the Eaton Vickers PVXS Series, a powerhouse in high-pressure axial piston technology. Part of the legendary Hydrokraft range, the PVXS series—ranging from PVXS066 to PVXS250—is designed for industrial environments where uptime is critical. Models like the PVXS-130M04R are capable of sustaining continuous pressures up to $350\text{ bar}$ ($5000\text{ PSI}$) while operating with an incredibly low noise signature. Engineered for heavy-duty metal forming, marine engineering, and steel mill applications, the PVXS series is the definitive choice for reliability, efficiency, and long-term durability.

Technical Specifications (Bulleted List)

• Series: Vickers PVXS (Hydrokraft) Axial Piston Variable Pump.

• Displacements: 66, 90, 130, 180, and 250 ($\text{cm}^3\text{/rev}$).

• Max Pressure: Continuous $350\text{ bar}$ / Intermittent $420\text{ bar}$.

• Efficiency: High volumetric efficiency up to $95\%$ under rated conditions.

• Control Modes: Pressure Compensation, Load Sensing, Power Limiting, and Proportional Control.

• Mounting: SAE and ISO standard flanges and shafts available.

Key Technical Advantages

• Superior Load Handling: Built with oversized shaft bearings to withstand the severe shock loads typical of hydraulic presses and metal shears.

• Ultra-Quiet Performance: Advanced fluid flow design and valve plate geometry minimize hydraulic pulsation, leading to a much quieter shop floor.

• Heavy Industrial Design: The Hydrokraft lineage ensures that every internal component is built for $24/7$ operational cycles in harsh environments.

• Precision Control Logic: Highly responsive control options allow for seamless integration into sophisticated automated manufacturing lines.

Application Areas

• Metalworking Machinery: Hydraulic presses, stamping machines, and shears.

• Marine & Offshore: Deck machinery, winches, and offshore power units.

• Civil Engineering: Tunneling machines and heavy-duty lifting systems.

Expert Maintenance Tips

• Proper Priming: Before initial start-up, the pump case must be filled with clean hydraulic oil through the drain port. Failure to do so will cause catastrophic damage to the swashplate and piston shoes within seconds.

• Case Drain Integrity: Ensure the drain line is plumbed directly to the reservoir without any restrictions. Excessive backpressure at the drain port is the leading cause of shaft seal leaks on PVXS130 models.

• Fluid Condition: To maximize the life of the Hydrokraft internals, maintain an oil cleanliness level of $ISO\text{ 17/15/12}$. Particulate contamination is the primary enemy of high-pressure piston surfaces.
