Parker Denison P6P P7P P11P P14P Piston Pump | P7P3L1A9A2A00 | P14P-3R1A-8A4B

LIC Hydraulic offers a complete range of Parker Denison P Series (P6P, P7P, P11P, P14P) axial piston pumps and hybrid combinations. Engineered for heavy-duty open-circuit applications, these pumps are built to withstand the most demanding duty cycles in industrial and mobile environments. Models like P14P-3R1A-8A4B represent the high-efficiency Hybrid technology, combining the high-pressure capabilities of a piston pump with the low-noise, high-flow characteristics of a vane pump. Whether you are replacing a P7P3L1A9A2A00 or a P7P2R1A5C2B, our units provide 100% original interchangeability, matching OEM performance curves and mounting dimensions precisely.

Technical Specifications

Key Technical Advantages

• Durable Bearing System: Equipped with high-capacity tapered roller bearings to handle substantial side loads, ensuring long-term reliability in high-cycle forging and pressing apps.

• Quiet & Stable Operation: Advanced port plate timing reduces flow ripples and structural noise, making these pumps suitable for indoor factory installations.

• Versatile Hybrid Capability: The P14P series allows for a T7 vane pump to be integrated on the same shaft, providing a multi-circuit power source from a single drive, which saves space and reduces plumbing complexity.

• Precision Control: High-response swashplate servos provide accurate displacement control, enhancing overall energy efficiency and reducing heat generation.

Application Areas

• Metal Processing: Extrusion presses, stamping machines, and hydraulic balers.

• Energy & Mining: Oil rig power units and heavy-duty drilling equipment.

• Marine: Deck cranes, winch drives, and large steering systems.

Expert Maintenance Tips

• Case Drain Management: Always use a dedicated case drain line that returns to the tank below the oil level. Backpressure in the housing should never exceed $2\text{ bar}$ to prevent shaft seal blowout.

• Pre-Start Priming: It is mandatory to fill the pump case with clean hydraulic fluid before the initial startup. Dry running, even for seconds, will cause catastrophic failure of the piston and shoe assembly.

• Fluid Cleanliness: To maintain the efficiency of the precision-ground valve plates, keep the system at an ISO 4406 18/16/13 cleanliness level or better.
