Parker PV Series Axial Piston Pump | PV016 PV180 PV016R1K1T1NMMW | Variable Displacement

The PV Series axial variable displacement piston pumps by Chengyuan Hydraulic are high-pressure power units engineered for full compatibility with Parker Hannifin industrial standards. This range covers sizes from the compact PV016 to the high-capacity PV180 (e.g., PV180R1K1T1WMMC). Designed for the most demanding industrial environments, PV pumps offer exceptional dynamic response and high volumetric efficiency. Featuring reinforced housings and optimized valve plate geometries, they maintain ultra-low noise levels across the entire pressure spectrum. As a premier interchangeable solution, every unit offers 100% original-place interchangeability and undergoes 100% simulated condition testing to ensure that pressure compensation and Load Sensing (LS) control logic match OEM technical specifications perfectly.

Key Technical Advantages:

• Optimized Compression Chamber: The PV series features an advanced internal compression volume design that significantly reduces flow ripple. This minimizes overall hydraulic system vibration and lowers operational noise by $3\text{ to } 5\text{ dB}$ compared to equivalent models.

• Heavy-Duty Axial/Radial Bearings: Equipped with oversized tapered roller bearings, the pump can handle high radial and axial shaft loads. This ensures drive shaft alignment even under high-pressure cycles, significantly extending the life of the shaft seals and rotating groups.

• Fast Dynamic Response: The variable displacement mechanism provides ultra-fast response times. Switching from zero to maximum flow is near-instantaneous. Coupled with precise Load Sensing control, it enables power-on-demand, improving energy efficiency by over $25\%$.

• Modular Compensator Design: All PV series compensators utilize a modular architecture. This allows for easy field upgrades (such as adding remote control or unloading functions) and simplifies maintenance, greatly enhancing machine flexibility.

Application Areas:

• Industrial Presses: Primary power source for metal forming, shearing, and stamping equipment.

• Plastic Machinery: High-pressure closed-loop systems for injection molding machines.

• Test Rigs: High-pressure pulsation test stands for aerospace and automotive components.

Expert Maintenance Tips:

• Initial Priming: After installation, the pump housing MUST be filled with clean hydraulic oil through the drain port. Run the pump at idle or low pressure for $10\text{ to } 15$ minutes to bleed all air.

• Case Drain Monitoring: Ensure the case drain pressure remains below $0.2\text{ MPa (2 bar)}$. The drain line must lead directly to the tank, and the outlet must be submerged below the oil level to prevent air ingestion.

• Viscosity Management: Recommended oil is ISO VG 46 anti-wear fluid. In high-temperature operations, monitor oil viscosity closely to prevent the lubrication film from thinning, which can lead to premature wear of rotating components.
