Product Description
890-EI Series Heavy-Duty High-Pressure Hydraulic Gear Pumps
Product Overview: The 890-EI Series represents the powerhouse of heavy-duty hydraulic energy, designed for the most demanding industrial environments. This featured selection focuses on key models: 890-EI-0250-FB2-S201, 890-EI-0630-RS2-C313, and the high-capacity 890-EI-1000-RS2-C502. Engineered with reinforced iron or high-tensile alloy bodies and advanced axial gap compensation, these pumps are specifically built to withstand continuous high pressure (up to 31.5 MPa) in large-scale construction machinery and industrial presses.
Key Technical Advantages:
100% Industrial Grade Interchange: Strictly adheres to international industrial specifications. Suffix codes like FB2-S201 and RS2-C502 guarantee that mounting flanges (SAE or specific industrial standards), shaft ends, and port positions are perfectly compatible with mainstream hydraulic units.
Heavy-Duty Pressure Resilience: Rated for operating pressures ranging from 21-25 MPa, with peak surges up to 31.5 MPa. Reinforced gear sets provide exceptional fatigue and impact resistance under heavy cycles.
High Volumetric Efficiency: Featuring precision pressure-compensated wear plates to minimize internal leakage, maintaining efficiencies over 93% during variable speed and load conditions, effectively reducing system heat and energy loss.
Superior Sealing & Resistance: Equipped with high-grade Viton or specialized seals, these pumps are adapted for broad temperature ranges, effectively preventing oil leaks even in high-heat operations.
Smooth & Stable Output: The precision-ground gear profiles drastically reduce hydraulic ripples and mechanical noise, protecting downstream control valves and enhancing system stability.
Detailed Models & Parameters:
Core Series: 890-EI Heavy Duty Performance Series.
Model Keywords: 890-EI-0250-FB2-S201, 890-EI-0630-RS2-C313, 890-EI-1000-RS2-C502.
Displacements: Covering large flow specs including 25cc, 63cc, and 100cc/rev.
Pressure Ratings: Rated at 25 MPa; Peak pressure up to 31.5 MPa (4560 PSI).
Target Applications: Dump truck hydraulics, large excavators, injection molding main pumps, hydraulic balers, and heavy material handling equipment.
