Product Description
IPH Series High-Performance Internal Hydraulic Gear Pumps
Product Overview: The IPH Series stands as a global industry benchmark for “Silent Hydraulic Pumps.” As a premier internal gear pump, it is specifically engineered for high-pressure applications requiring extended service life and minimal operational noise. Utilizing advanced radial and axial gap compensation mechanisms, the IPH series maintains an exceptional volumetric efficiency above 95% across the entire pressure spectrum. This featured range includes core models: the compact IPH2-020-101, the heavy-duty IPH/6-80-101, and the high-displacement IPH/6/100-101. Its superior performance makes it the definitive power source for servo-driven injection molding machines and precision hydraulic stations.
Key Technical Advantages:
Ultra-Quiet Performance: Featuring a specialized internal gear profile, these pumps deliver remarkably smooth operation with noise levels significantly lower than traditional external gear pumps, even at 25 MPa.
Low Pulsation Delivery: Virtually eliminates flow and pressure ripples, drastically reducing system vibration, protecting precision proportional valves, and enhancing actuator control accuracy.
Superior High-Pressure Stability: Rated for continuous working pressures of 25-30 MPa. Automatic compensation technology ensures stable flow output throughout the pump’s lifecycle.
Optimized for Servo Systems: Perfect for integration with servo motor drives, supporting high-pressure holding at low RPMs—the core component for modern energy-saving hydraulics.
Target Applications: Servo-hydraulic injection molding machines, precision press brakes, rubber machinery, die-casting machines, and laboratory hydraulic test benches.
