Nachi IPH Series High-Performance Industrial Internal Gear Pumps

Product Overview: The Nachi IPH Series is a cornerstone of precision in hydraulic power transmission, globally recognized for its exceptional low-noise performance and long-term stability under high-pressure conditions. This selection features diverse configurations, ranging from the single pump model IPH-2B-8-11 and highly flexible double pumps IPH-22B-5-5-L/R, to mid-to-high displacement models like IPH-4-20-101 and complex specs like IPH-36B-13-80-11. Utilizing radial and axial gap compensation mechanisms, these pumps maintain elite volumetric efficiency at peak pressures up to 30 MPa, making them the ideal core components for injection molding machines, metal forming presses, and servo-hydraulic systems.

Key Technical Advantages:

• Ultimate Silence & Smoothness: The internal gear meshing architecture drastically reduces operational noise and pressure ripples, protecting sensitive downstream proportional valves and sensors.

• Superior Volumetric Efficiency: Automatic gap compensation technology ensures efficiencies over 95% across the full pressure range, minimizing energy loss and heat buildup.

• Flexible Tandem/Double Pump Design: Configurations like IPH-22B and IPH-36B enable dual-circuit oil delivery from a single drive source, significantly optimizing installation space.

• Directional Versatility: Available in L (Counter-clockwise) and R (Clockwise) specifications (e.g., IPH-22B-5-5-R) to perfectly match various motor drive layouts.

• Extended Service Life: Precision-ground gear components and reinforced pump bodies ensure outstanding fatigue resistance under continuous heavy-load operations.
