Parker PGP517 & PGP076 Series High-Performance Tandem Hydraulic Gear Pumps

Product Overview: The Parker PGP Series serves as the premier power source for heavy-duty hydraulic systems, renowned for its exceptional durability and high efficiency in extreme environments. This selection features key precision tandem configurations: Part Number 3339122193 (PGP517B0520AD1K6NT4T3S-517A028) and the heavy-duty cast iron model 3169620138 (PGP076B278BI…). Constructed with a high-strength three-piece design, these pumps maintain elite volumetric efficiency at peak pressures up to 28 MPa. Their versatile tandem architecture allows a single drive source to power two independent circuits simultaneously, making them the first choice for OEM replacements in excavators, cranes, and heavy loaders.

Key Technical Advantages:

• Superior Pressure Resilience: Rated for a continuous operating pressure of 250 Bar with peaks reaching 280 Bar (4060 PSI), featuring heat-treated high-strength journals built to withstand frequent load shocks.

• Highly Integrated Tandem Design: The PGP517B/PGP076B series supports multi-stage configurations (e.g., 52cc+28cc combinations), significantly optimizing installation space and lowering overall system maintenance costs.

• High Efficiency & Low Internal Leakage: Equipped with automatic axial pressure-compensated side plates to minimize internal leakage, maintaining efficiencies over 93% throughout its service life while reducing heat buildup.

• Heavy-Duty Construction: The PGP076 utilizes a reinforced cast iron body for superior fatigue resistance, ideal for continuous high-intensity operations in mining and harsh construction sites.

• 100% OEM Compatibility: Strictly adheres to standard interface codes (such as AD1K6, T4T3), ensuring identical flange patterns, shaft ends, and port positions for guaranteed “Plug-and-Play” replacement.
