Parker PV180R1L1T1NUDR Piston Pump | PV180 Series Axial Variable Displacement Pump

The PV180 Series axial piston variable displacement pumps from Chengyuan Hydraulic are heavy-duty power components fully compatible with Parker industrial standards. Featuring a robust swashplate design for open-circuit systems, the PV180R1L1T1NUDR is engineered for the most demanding industrial environments. We utilize reinforced piston-shoe assemblies and optimized port plates to ensure maximum efficiency. Every unit undergoes 100% simulated full-load testing to guarantee that volumetric efficiency and response times match the original specifications at 350 Bar, ensuring 100% original-place interchangeability.

Key Technical Advantages:

• UDR Precision Compensation: The integrated UDR control supports remote pressure regulation. When the system reaches the set pressure, the pump rapidly destrokes to zero flow, minimizing standby power consumption and protecting the system from over-pressurization.

• Pre-Compression Quiet Technology: Optimized porting geometry reduces fluid impact and vibration during piston transition. This design results in a noise reduction of 4-6 dB(A) compared to conventional piston pumps.

• Heavy-Duty Bearing Layout: Oversized tapered roller bearings support the shaft assembly, providing exceptional resistance to radial loads and axial shocks. This ensures a long service life even in 24/7 continuous industrial operations.

• Thru-Drive Capability: The modular shaft design allows for easy mounting of auxiliary pumps (gear pumps or smaller piston pumps) for multi-circuit configurations, offering maximum flexibility in power unit design.

Application Areas:

• Injection Molding: Power source for mold clamping and injection in large machines.

• Steel & Metallurgy: Blast furnace equipment and plate shearing hydraulic stations.

• Forging Equipment: Automated forging lines and primary pumps for heavy hydraulic presses.

• Marine Engineering: Winch drive systems and marine power units.

Expert Maintenance Tips:

• Priming & Air Bleeding: Before the first start-up, fill the pump housing with clean hydraulic oil through the L1 drain port. Never rotate the drive shaft with a dry housing to avoid burning the piston shoes.

• Case Drain Pressure: Ensure the drain line goes directly to the tank with zero restriction; case pressure must not exceed 2 Bar to prevent shaft seal failure or swashplate response lag.

• Temperature Control: For continuous operation at 350 Bar, maintain reservoir oil temperature between $45°C$ and $60°C$ to preserve optimal lubrication film strength.
