Product Overview
The HAWE HQI2-019RA03-11S122 is a high-performance external hydraulic gear pump engineered by HAWE Hydraulik, a globally recognized manufacturer of precision hydraulic components. Operating on the positive displacement principle, this pump utilizes a pair of precision-meshed external spur gears to draw in and pressurize hydraulic fluid, delivering a nominal displacement of approximately 19 cm³/rev. The HQI2 series is designed for robust industrial duty, offering consistent volumetric efficiency, low pulsation, and reliable performance in continuous operating systems. As a fixed-displacement gear pump, it serves as a dependable pressure and flow source for a wide range of hydraulic circuits, including lubrication systems, power packs, and mobile machinery hydraulic drives.
