Nachi IPH Series Pump | IPH-6B-80, IPH-4B-25 | High Pressure Internal Gear Pump

Nachi IPH Series High-Performance Internal Gear Pumps

Product Overview: The Nachi IPH Series is a globally recognized pioneer in high-pressure internal gear pump technology. This selection covers core displacements from the compact IPH-2B to the high-capacity IPH-6B, featuring featured models such as IPH-6B-80-T-21, IPH-4B-20-LT-20, and IPH-2B-3.5-11. Utilizing patented “dual-stage pressure compensation,” IPH pumps maintain elite volumetric efficiency even under continuous rated pressure. These pumps are the premier choice for industrial presses and injection molding machines, as well as hydraulic power sources for large tractors, harvesters, and mobile machinery.

Key Technical Advantages:

• Patented Dual-Stage Compensation: Employs both radial and axial gap compensation, maintaining efficiencies above 95% even during extended high-pressure operation.

• Ultra-Quiet Performance: The internal gear design operates at significantly lower decibel levels than traditional pumps, drastically improving comfort in agricultural and industrial settings.

• Extreme Pressure Durability: Constructed with high-strength cast-iron housings, these pumps provide stable pressure ratings ideal for tractor lifting systems and power steering.

• Superior Suction Performance: Optimized internal flow galleries ensure smooth oil intake even at high RPMs or with higher viscosity hydraulic fluids.

• Extended Wear Resistance: Critical rotating components are heat-treated for enhanced contamination resistance and extended maintenance intervals.
