IGH & IGC Series High Pressure Internal Gear Pump | IGH-4F-25, IGC-3E, IGC-5F

IGH/IGC Series High-Performance Internal Gear Pumps

Product Overview: The IGH/IGC Series stands as the “Silent Power Pioneer” in servo-hydraulic power systems. As a high-pressure internal gear pump featuring both axial and radial pressure compensation, it is specifically optimized for use with servo motors in injection molding machines, press brakes, and precision presses. This range highlights comprehensive specifications, covering compact 2E/2F, medium displacement 3E/3F, 4E/4F, and high-power 5E/5F models. Utilizing unique gear engagement technology, models like IGH-4F-25 maintain exceptionally low flow pulsation even at pressures up to 30 MPa—serving as the definitive core component for modern energy-saving hydraulic systems.

Key Technical Advantages:

• Superior Servo Adaptability: Optimized for high-frequency start-stop and pressure-holding cycles, perfectly matching servo-driven hydraulic systems for significant energy savings.

• Dual-Way Pressure Compensation: Features automatic axial and radial clearance compensation, maintaining volumetric efficiency above 95% even with varying oil viscosity or under high-pressure conditions.

• Ultimate Silent Operation: Utilizes a specialized straight-line tooth profile for smooth engagement. Operational noise is significantly lower than comparable vane or piston pumps, improving the factory environment.

• Ultra-Long Service Life: Constructed with high-wear-resistant materials and radial-balanced designs, minimizing bearing stress and ensuring high reliability under rigorous industrial conditions.

• Target Applications: Servo injection molding machines, high-precision hydraulic press brakes, brick presses, automated assembly equipment, and heavy-duty energy-saving industrial power units.
