Product Description
LIC Hydraulic’s Parker PVP Series axial piston pumps provide the perfect balance of high-pressure capability and compact design. Available in displacements from PVP16 to PVP48, this series is the industry standard for open-circuit variable displacement applications. For specific configurations like the PVP23302R21, these pumps feature a rugged cast-iron construction that excels in both mobile and industrial environments. With an intermittent pressure rating up to $310\text{ bar}$ ($4500\text{ PSI}$) and a variety of control options, the PVP series ensures maximum efficiency and longevity for your hydraulic power units.
Technical Specifications (Quick Reference)

Max Operating Pressure: Continuous $250\text{ bar}$ ($3600\text{ PSI}$); Intermittent $310\text{ bar}$.
Speed Range: Efficient operation up to $3000\text{ RPM}$ (displacement dependent).
Control Options: Pressure Compensator, Load Sensing, Remote Pressure Control.
Compatibility: 100% Drop-in replacement for Parker and other SAE standard piston pumps.
Key Technical Advantages
Heavy-Duty Cast Iron Housing: Provides superior vibration damping and structural rigidity compared to aluminum housings, resulting in quieter operation and higher pressure resistance.
Dynamic Response: The high-performance compensators react instantly to system demand changes, minimizing energy waste and heat generation during dwell cycles.
Optimized Porting: Large suction ports allow for excellent cold-start performance and reduced risk of cavitation at high speeds.
Thru-Shaft Capability: Available options for tandem pump mounting, allowing you to drive multiple circuits from a single prime mover.
Application Areas
Industrial Power Units: Central hydraulic systems for manufacturing plants and factory automation.
Machine Tools: Reliable high-pressure supply for clamping and positioning actuators.
Construction Equipment: Auxiliary power for pavers, compactors, and lifting platforms.
Material Handling: Primary drive pump for forklifts and specialized transport vehicles.
Expert Maintenance Tips
Priming the Case: Before the first start, always fill the pump case with clean hydraulic oil via the highest drain port. Running the pump “dry” for even a few seconds will cause catastrophic failure of the piston shoes.
Seal Inspection: Regularly check the shaft seal and mounting flange for any signs of weeping. In the PVP series, early detection of external leaks can prevent internal air ingestion which leads to erratic control.
Suction Line Integrity: Ensure the suction hose is rated for vacuum and is not collapsing. Any restriction in the inlet will cause a noticeable “whine” and rapidly destroy the cylinder block.
