CML IGH & IGM Series Internal Gear Pump | IGM-4F-25, IGH-4F-25-R | Silent Servo Pump

CML IGH & IGM Series High-Performance Silent Internal Gear Pumps

Product Overview: The CML IGH, IGM, and IGC Series are the industry standard for “High Pressure, Ultra-Silence, and Long Service Life.” These internal gear pumps are specifically engineered for modern servo-hydraulic drive systems, capable of handling continuous high pressures up to 30 MPa. This featured range includes the entire lineup: from the popular IGM-4F-25 and IGH-4F-25-R-20 to the full displacement spectrum of 4F, 5F, and 6F frames. Its unique internal meshing design ensures ultimate operational smoothness under variable-speed servo conditions.

Key Technical Advantages:

• Ultra-Quiet & Low Pulsation: Utilizing the internal gear meshing principle, these pumps operate with minimal noise. Pressure ripples are typically under 2%, significantly enhancing system control precision and extending the life of hydraulic components.

• Dual Gap Compensation: Equipped with automated radial and axial pressure compensation mechanisms. Even at high pressures of 25-30 MPa (250-300 Bar), volumetric efficiency remains consistently above 95%.

• Optimized for Servo Drives: Exceptional low-speed, high-pressure capability (stable performance as low as 100 RPM) allows perfect synchronization with servo motors for maximum energy efficiency.

• 100% Direct OEM Replacement: Manufactured strictly to international flange and shaft specifications. Codes like 4F/5F/6F define the frame sizes, ensuring seamless compatibility with the mounting interfaces of mainstream injection molding and bending machines.

• Target Applications: CNC bending machines, precision injection molding machines, ceramic brick presses, hydraulic elevators, and various industrial closed-loop servo hydraulic circuits.
