Injection Molding Machine Hydraulic Pump | EIPC3, EIPC5 Series | EIPC3-064, EIPC3-040, EIPC5-080 | Internal Gear Pump

EIPC Series High-Performance Internal Gear Pumps for Injection Molding Machines

Product Overview: The EIPC Series is the premier powerhouse for modern injection molding machine (IMM) servo hydraulic systems, engineered for high efficiency, ultra-low noise, and extreme industrial durability. This featured selection includes core specifications: EIPC3-064RA23-10, EIPC3-040RB23-10, and the high-flow EIPC5-080RA23-10. Featuring patented axial and radial pressure compensation technology, these pumps excel under variable-speed servo conditions, making them the top choice for energy-saving machine replacements and system upgrades.

Key Technical Advantages:

• Servo System Optimized: Specifically designed for the frequent speed variations and pressure-holding cycles of servo motors, supporting stable high-pressure output at extremely low RPMs.

• Dual Pressure Compensation: Unique radial and axial compensation mechanisms maintain volumetric efficiency over 95% throughout the pump’s service life, effectively reducing oil overheating.

• Ultra-Quiet Operation: The internal meshing gear profile drastically reduces decibel levels and fluid ripples, significantly improving the factory floor environment and extending hydraulic line life.

• 100% Plug-and-Play Replacement: Model suffixes like RA23 and RB23 guarantee that mounting flanges (SAE standards), shaft ends, and port configurations are fully compatible with major IMM brands (e.g., Haitian, Chen Hsong, Borch).

• High Pressure Resilience: Reinforced housing design supports a continuous operating pressure of 25 MPa (250 Bar), with peaks reaching 31.5 MPa.
