Product Overview
The NACHI IPH-6B-80-11 is a high-performance internal gear pump manufactured by NACHI-FUJIKOSI, engineered for precision fluid power delivery in demanding industrial hydraulic systems. Utilizing an internal gear working principle, this pump features a pinion gear driving an internal ring gear within a crescent seal arrangement, delivering smooth, low-pulsation flow with exceptional volumetric efficiency. The IPH series is renowned for its quiet operation, compact footprint, and ability to maintain stable performance across a wide viscosity range. The 80 displacement code indicates a nominal output of approximately 80 cm³/rev, making it suitable for medium-to-high flow applications where reliability and energy efficiency are critical. This pump serves as a direct replacement component in NACHI hydraulic power units and is widely deployed in injection molding, machine tool, and industrial press circuits.
