Caterpillar Series Gear Pumps are widely used in Caterpillar construction machinery and are primarily supplied to overseas customers.
The Caterpillar-compatible gear-pump series is developed around construction-equipment part numbers and mounting interfaces. It covers different displacements, rotations, SAE splines, and port configurations. Selected models use lightweight aluminum construction, wear-resistant treatment, and pressure-balanced design.
The products can be matched by equipment part number for OEM or spare-parts selection and are suitable for loaders, bulldozers, and other construction equipment. Any “direct replacement” claim should be used only after dimensional, performance, and test validation.
