Product Description
Parker PGP517 Series High-Performance Industrial Hydraulic Gear Pumps
Product Overview: The Parker PGP517 Series stands as a dynamic powerhouse for global mobile hydraulic systems. This featured selection includes core precision part numbers: 3339131040, 3339121186, 3339530018, and 3339111608. Engineered with a unique three-piece reinforced aluminum construction, these pumps are designed to deliver exceptional reliability at peak pressures up to 28 MPa while maintaining a lightweight footprint. As the premier choice for loaders, excavators, and heavy-duty machinery, the PGP517 series is renowned for its superior volumetric efficiency and resilience under extreme temperature conditions.
Key Technical Advantages:
Superior Pressure Resilience: Rated for a continuous operating pressure of 250 Bar (3625 PSI) with peaks reaching 280 Bar, built to handle the frequent load fluctuations in heavy-duty machinery.
High Volumetric Efficiency: Featuring automatic axial gap compensation to minimize internal leakage, maintaining efficiencies over 93% throughout the pump’s service life and reducing overall energy consumption.
Lightweight & Robust Construction: Utilizes high-strength extruded aluminum bodies with cast iron end covers, providing an excellent power-to-weight ratio and optimizing machine load distribution.
100% Plug-and-Play Replacement: Strictly adheres to original Parker OEM specifications, ensuring identical flange patterns, shaft ends (splined or keyed), and port specifications for guaranteed seamless installation.
Quiet & Low-Pulsation Operation: Optimized gear profiles drastically reduce operational noise and pressure ripples, protecting downstream hydraulic valve components.
