Product Description
Parker PGP620 Series High-Performance Hydraulic Gear Pumps
Product Overview: The Parker PGP620 Series is a premier power core designed to meet the extreme power density requirements of modern mobile and industrial applications. This featured range includes critical part numbers: 7029120077, 333G5390, 7029122021, and the specialized 7029111248 (PGP620A0190CM3H3VE6E5B1B1). Featuring a unique three-piece construction (cast iron end covers with an aluminum body), the PGP620 offers significantly higher pressure ratings and a longer service life compared to traditional all-aluminum pumps.
Key Technical Advantages:
100% Direct OEM Replacement: Manufactured strictly to Parker Hannifin and major OEM standards (such as Caterpillar, JCB). Part numbers like 7029120077 guarantee that mounting flanges, SAE splined shafts, and port configurations match original systems seamlessly.
Reinforced Medium-to-Heavy Duty Construction: Cast iron end covers provide superior fatigue resistance under high-pressure cycling, with rated continuous pressures up to 27.5 MPa (275 Bar) and peaks reaching 31 MPa.
Superior Volumetric Efficiency: Equipped with automated axial gap-compensated floating side plates, maintaining volumetric efficiency above 95% throughout its service life, effectively minimizing internal leakage and oil overheating.
Exceptional Environmental Resilience: Utilizing high-performance seals like Viton (Code VE6), ensuring reliable sealing performance in extreme high or low-temperature environments.
Target Applications: Pilot and auxiliary circuits for heavy excavators, steering pumps for wheel loaders, specialized vehicle hydraulic systems, and industrial waste compactors.
