Product Description
Caterpillar (CAT) Aftermarket High-Performance Heavy-Duty Hydraulic Gear Pumps
Product Overview: This series of hydraulic gear pumps represents premium aftermarket replacements specifically engineered for Caterpillar (CAT) construction machinery. It covers core part numbers 326-9111-190 (3269111190), 326-91-10461 (3269110461), and 326-9131-031 (3269131031). Built with the PGP315 heavy-duty cast iron body structure, these pumps are engineered to withstand the most rigorous high-pressure environments (Rated 25 MPa) and dusty conditions found in mining and construction sites. This series ensures ultimate stability for the host system under heavy-duty cycles, whether as a direct OEM replacement or a performance upgrade.
Key Technical Advantages:
100% Direct OEM Interchange: Manufactured strictly to CAT installation standards. Model codes like PGP315A193PQAB07-66 define precise flange specs, shaft splines, and port orientations for a seamless “plug-and-play” fit.
High-Strength Cast Iron Sectional Design: Featuring high-tensile gray iron bodies, these pumps offer superior impact and fatigue resistance to handle continuous high-frequency pressure spikes without deformation.
Advanced Axial Gap Compensation: Equipped with pressure-balanced floating side plates, maintaining a volumetric efficiency above 95% throughout its service life, effectively reducing oil overheating.
Heavy-Duty Bearing Design: Internal large-scale self-lubricating bearings provide exceptional wear resistance in extreme heat and under harsh load conditions.
Target Applications: Caterpillar excavator hydraulic circuits, wheel loader steering systems, motor grader auxiliary power, and various heavy-duty mobile hydraulic units.
