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 critical displacement models: the 890-EI-0250-FS2-S202 (for high-precision compact applications) and the 890-EI-0800-RS2-C503 (for mainstream high-flow applications). Utilizing cutting-edge axial and radial gap compensation, these pumps deliver peak efficiency during the demanding holding-pressure phases of the molding cycle. They are the premier “drop-in” replacement or upgrade for servo systems in brands like Haitian and Yizumi.

Key Technical Advantages:

  • Ultra-Quiet Operation: The internal gear principle ensures significantly lower noise levels than traditional piston pumps, maintaining a quiet manufacturing environment even under high-load conditions.

  • 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.

  • 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 iron housings and specialized hardened components, ensuring a low failure rate under grueling 24/7 production cycles.

Detailed Models & Parameters:

  • Core Series: 890-EI Internal Gear Series.

  • Model Keywords: 890-EI-0250-FS2-S202, 890-EI-0800-RS2-C503, 890-EI-0400, 890-EI-1000.

  • Displacements: Features 25 cm³/rev (0250) and 80 cm³/rev (0800) configurations.

  • Maximum Pressure: Rated at 330 Bar (4785 PSI).

  • Mounting: Standard flange mounting with various shaft options.

  • Target Applications: Primary power for servo IMMs, servo press brakes, die-casting machinery, and energy-efficient HPUs.
