Product Overview

The Parker PV180R9K1T1NULW0524 (OEM reference 27626119/001) is a heavy-duty, variable displacement axial piston pump engineered for high-pressure open-circuit hydraulic systems. As a member of the renowned Parker PV series, this pump utilizes a proven swashplate design with a rotating cylinder barrel and precision-ground axial pistons to deliver exceptional volumetric efficiency and reliable power density. The “180” designation indicates a nominal geometric displacement of 180 cm³/rev, positioning this unit in the high-flow tier of industrial piston pumps. Its variable displacement mechanism allows for infinite flow adjustment between zero and maximum, enabling precise actuator speed control, energy-efficient pressure-compensated operation, and reduced system heat generation. This pump is the definitive choice for demanding continuous-duty applications where high pressure, long service life, and precise control are non-negotiable.

Technical Specifications

Engineering Features & Advantages

• Precision Performance: The swashplate and piston-shoe assembly are precision-lapped and hydrostatically balanced, ensuring high volumetric efficiency, minimal internal leakage, and stable flow output even at elevated operating pressures.
• Advanced Variable Control: The integrated displacement control (pressure, flow, or load-sensing) allows the pump to match system demand instantly, significantly reducing power consumption and oil temperature in idle or low-demand cycles.
• Industrial Reliability: Built for continuous operation under severe industrial conditions, featuring a robust cast-iron housing, heavy-duty bearings, and a hardened cylinder barrel for extended service life in high-cycle applications.
• Direct Fit Replacement: Exact dimensional and functional compatibility with original OEM standards, ensuring drop-in replacement for existing Parker PV series installations without modification to mounting or plumbing.

Typical Industrial Applications

This high-performance axial piston pump is ideally suited for heavy industrial scenarios including plastic injection molding machines, metallurgical presses and forging equipment, construction and marine hydraulics (winches, cranes, and deck machinery), and high-power CNC machine tools. Its ability to maintain high pressure under variable flow demands makes it a critical component in any system requiring precise force control and energy-efficient operation.
