High Pressure Gear Pump for Injection Molding Machine | 890-EI-1600-RK2-C601, 890-EI-0640-RS2-C502

890-EI Series High-Pressure Internal Gear Pumps for IMM

Product Overview: The 890-EI Series is a range of high-pressure internal gear pumps specifically engineered for modern servo-driven injection molding machines (IMM). This selection features core models: 890-EI-1600-RK2-C601 (High Displacement) and 890-EI-0640-RS2-C502. Utilizing advanced axial and radial gap compensation technology, these pumps deliver peak efficiency during the demanding holding-pressure phases of the injection cycle. It is the premier “drop-in” replacement or upgrade for servo-energy-saving systems in brands like Haitian, Chen Hsong, and Yizumi.

Key Technical Advantages:

• Ultra-Low Noise Technology: The internal gear principle ensures exceptionally quiet operation, significantly improving the acoustic environment of manufacturing facilities even under high-load conditions.

• Continuous High-Pressure Performance: Rated for pressures up to 330 Bar, providing the stability required for precise molding and consistent product dimensions.

• Servo-Drive Optimization: Features low rotational inertia, perfectly matching the rapid start-stop and variable speed requirements of servo motors for millisecond response times.

• Elite Energy Efficiency: Maintains superior volumetric efficiency even at low RPMs during holding pressure, drastically reducing oil temperature rise and power consumption.

• Industrial-Grade Durability: Constructed with specialized hardened gear sets and high-strength iron housings, ensuring tens of thousands of operational hours under 24/7 production cycles.
