Nachi IPH Series Pump | IPH-3-10, IPH-4A-25, IPH-44B-25-25 | Low Noise Internal Gear Pump

Nachi IPH Series High-Performance Low-Noise Internal Gear Pumps

Product Overview: The Nachi IPH Series is a globally recognized benchmark for high-pressure and low-noise technology in the industrial hydraulic sector. This selection features core specifications including the single pump models IPH3-10-201 and IPH-4A-25-LT-20, alongside highly flexible tandem configurations like IPH-44B-25-25-E-11 and IPH-46B-32-100-TT. Utilizing patented axial and radial pressure compensation, IPH pumps deliver near-pulsation-free flow and exceptionally low noise levels even at extreme pressures of 30 MPa. It is the premier choice for CNC machine tools, die-casting machinery, injection molding servo systems, and precision hydraulic power units (HPUs).

Key Technical Advantages:

• Ultra-Quiet Technology: The unique internal gearing principle combined with high-precision manufacturing drastically reduces operational noise, ideal for noise-sensitive indoor workshop environments.

• Dual-Directional Compensation: Incorporates both axial and radial pressure compensation to minimize internal leakage, ensuring elite volumetric efficiency throughout the pump’s entire service life.

• Superior High-Pressure Stability: Built to withstand frequent loading and unloading cycles with exceptional fatigue resistance and stable pressure ratings.

• Flexible Tandem Integration: Supports diverse displacement combinations (e.g., IPH-44B, IPH-46B double pumps) via a single drive shaft, delivering independent oil sources and optimizing system layouts.

• Low Pulsation Output: Significantly reduces pressure and flow ripples, ensuring smooth and precise movements for sensitive hydraulic actuators and precision cylinders.
