Product Description
Parker PGP511 Series High-Performance Hydraulic Gear Pumps
Product Overview: The Parker PGP511 Series is recognized as a premium power source for mobile hydraulic equipment, renowned for its exceptional power density and durability. This featured range includes core part numbers and specification codes: 334-9111-152 (PGP511A0110CS1D4NJ7J5B1B1) and the higher displacement 334-9111-189 (PGP511A0210CA1H2NL2L2B1B1). Featuring a three-piece split-body design, these pumps are engineered to provide stable, long-lasting high-pressure hydraulic power in the most demanding construction and industrial environments.
Key Technical Advantages:
100% Direct OEM Replacement: Manufactured strictly to Parker Hannifin and major OEM standards like Caterpillar. Part numbers such as 334-9111-152 guarantee that mounting flanges (e.g., SAE A 2-bolt), drive shafts (Splined/Keyed), and port configurations match original systems seamlessly.
High Pressure Resilience: Built with high-strength extruded aluminum bodies and precision-ground gear sets, rated for continuous pressures up to 25 MPa (250 Bar) with peaks reaching 28 MPa, handling instantaneous loads with ease.
Superior Volumetric Efficiency: Equipped with axial pressure-compensated floating side plates, maintaining volumetric efficiency above 94% throughout its service life, effectively minimizing internal leakage and oil overheating.
Whisper-Quiet & Smooth Operation: Optimized gear tooth profiles significantly reduce operational noise and flow ripples, making it ideal for precision excavator pilot systems and forklift hydraulic circuits.
Target Applications: Caterpillar (CAT) excavator pilot pumps, main pumps for small-to-medium forklifts, harvester header drives, and industrial Hydraulic Power Units (HPU).
