Product Description
890-EI Series High-Pressure Internal Gear Pumps for Servo IMM
Product Overview: The 890-EI Series represents the high-performance core for modern servo-driven, energy-saving injection molding machines (IMM). This selection features two mainstream displacement models: the 890-EI-1250-RS2-C602 (for high-flow requirements) and the 890-EI-0640-RS2-C502 (for mid-range flow requirements). Utilizing cutting-edge axial and radial gap compensation, these pumps deliver peak efficiency and stability during the demanding holding-pressure phases of the molding cycle. They are the premier “drop-in” replacement or upgrade for servo systems in industry-leading brands like Haitian, Chen Hsong, and Yizumi.
Key Technical Advantages:
Ultra-Quiet Operation: The internal gear principle ensures significantly lower noise levels than traditional piston pumps, maintaining a mild acoustic profile even under high-load conditions to improve the manufacturing environment.
Superior High-Pressure Holding: Rated for continuous operation up to 330 Bar, providing the rock-solid stability required for precise molding and consistent part quality.
Perfect Servo Integration: Features low rotational inertia, matching the rapid start-stop and variable-speed requirements of servo motors for millisecond-level pressure response times.
Elite Volumetric Efficiency: Maintains high output efficiency even at low RPMs during holding pressure, drastically reducing oil temperature rise and overall energy consumption.
Industrial-Grade Longevity: Constructed with high-strength precision iron housings and specialized hardened components, ensuring a high level of reliability under grueling 24/7 production cycles.
