Product Overview
The Parker GPC450-B5F3-G510SR is a heavy-duty external gear pump from Parker Hannifin’s GPC series, engineered for reliable hydraulic power generation in demanding industrial circuits. It operates on the positive-displacement external gear principle: two precision-ground, hardened spur gears rotate in mesh within a high-tolerance aluminum alloy housing, trapping and displacing fluid between the gear teeth and the casing walls to deliver a continuous, pulsation-damped flow. With a nominal displacement of approximately 45 cm³/rev, this pump is designed to serve as a primary or auxiliary pressure source in open-loop hydraulic systems, offering robust performance, compact envelope dimensions, and excellent tolerance to contamination compared to more sensitive pump architectures.
