Product Description
Nachi IPH Series High-Pressure Low-Noise Internal Gear Pump
Product Overview: The Nachi IPH series is a recognized industry benchmark for high-pressure, low-noise internal gear pumps. Featuring unique axial and radial pressure compensation, this series maintains exceptional volumetric efficiency even at pressures up to 30 MPa. Flagship models such as the IPH-4B-25, IPH-3B-16-20, and IPH-6B-80-11 are extensively used in injection molding machines, hydraulic presses, machine tools, and precision power units. Its primary strength lies in its extended service life and silent operation that rivals the performance of piston pumps.
Key Technical Advantages:
Exceptional Low-Noise Operation: The internal gear design significantly reduces fluid pulsation and mechanical friction noise, making it ideal for indoor factory environments.
High-Pressure Volumetric Efficiency: Patented pressure compensation mechanisms ensure constant flow across the entire pressure range, with rated pressures of 25 MPa and peaks up to 30 MPa.
Durability & Wear Resistance: Precision-ground gear sets and a robust housing design withstand high-frequency switching and impact loads.
Versatile Tandem Configurations: The IPH series supports double-pump (IP-IPH) or multi-pump configurations with a shared inlet, simplifying hydraulic plumbing layouts.
100% Industrial Reliability: Manufactured to strict Nachi factory standards, offering various shaft and flange options for seamless drop-in replacement on original machinery.
