Product Description
Parker PGP620 & PGP640 Series Heavy-Duty Tandem Hydraulic Gear Pumps
Product Overview: The Parker PGP Series (encompassing PGP620 and PGP640) represents the premier power core for the most demanding engineering environments. Featuring a two-piece high-strength cast iron construction, these units offer superior fatigue resistance and exceptional power density. This range includes core tandem models: Part Numbers 7029120005, 7029120058, and the precision-configured PGP620B0360CE1H3WS7*D5C-620A0290XB1D5B1B1. Utilizing Parker’s advanced axial pressure compensation technology, the PGP600 series maintains a volumetric efficiency above 95% across the entire pressure range, serving as the definitive choice for excavators, loaders, and specialized vehicle hydraulic systems.
Key Technical Advantages:
Efficient Multi-Circuit Integration: Enables dual or multi-stage output from a single drive shaft (e.g., 36cc + 29cc combination), optimizing space while independently powering steering, lifting, or pilot circuits.
Heavy-Duty Cast Iron Construction: Compared to aluminum pumps, the PGP620/640 cast iron body withstands higher frequency pressure spikes (rated 27.5 MPa) while providing better acoustic performance and an extended service life.
Peak Volumetric Efficiency: Equipped with high-precision floating bushings that adjust in real-time to system pressure, minimizing internal leakage and maximizing output.
Extreme Condition Durability: Optimized for the high temperatures, dust, and frequent overload conditions common in construction machinery, offering superior wear resistance and contamination tolerance.
Target Applications: Heavy excavators, wheel loaders, motor graders, material handling machinery, and mining equipment.
Detailed Models & Parameters:
Core Series: Parker PGP/PGM 600 Series (PGP620, PGP640).
