Parker PGP Series High-Performance Single & Tandem Hydraulic Gear Pumps

Product Overview: The Parker PGP Series stands as the global benchmark for hydraulic power in industrial and mobile applications. This selection features precision models optimized for complex duty cycles, including the high-pressure aluminum pump 3309111356 (PGP502A0062CP2D1NE3E2B1B1), the heavy-duty cast iron PGP330/315 series, and the high-precision tandem configuration PGP620B0410AD1A3MT4T3S-620A016. Designed to meet the high-pressure demands (up to 28 MPa) and multi-circuit requirements of construction machinery and municipal vehicles, these pumps ensure superior reliability throughout their service life.

Key Technical Advantages:

• Precise OEM Replacement: Strictly adheres to original Parker specifications. Part numbers like 3309111356 guarantee that flanges (SAE standards), shaft ends (splined/keyed), and port positions are 100% identical to the original unit for seamless installation.

• Efficient Multi-Circuit Supply: Tandem configurations like the PGP620 allow a single drive shaft to power multiple independent systems (e.g., steering and lifting), optimizing piping layouts and reducing energy consumption.

• Superior Pressure Resilience: Rated for a continuous operating pressure of 25 MPa with peaks reaching 28 MPa (4060 PSI), built to absorb heavy load shocks in demanding environments.

• High Volumetric Efficiency: Featuring Parker’s patented axial pressure-compensated wear plates to minimize internal leakage, ensuring stable flow delivery across all RPM ranges.

• Rugged Heavy-Duty Construction: Models like PGP330/315 utilize high-tensile cast iron housings, offering exceptional durability for mining, construction, and other harsh operational conditions.
