XCMG XE2000 Original Hydraulic Pump Blind Flange (860149587) – The Sealing Guardian of Hydraulic Systems
XCMG XE2000 Dedicated Hydraulic Pump Blind Flange | Part Number 860149587 | Ultimate Sealing and Zero Leakage Guarantee

In the hydraulic system of the XCMG XE2000 large excavator, the hydraulic pump blind flange (860149587) is a key component ensuring the system’s sealing performance. This original equipment manufacturer (OEM) blind flange uses precision manufacturing processes and high-quality materials to provide your equipment with the most reliable sealing guarantee, ensuring that the hydraulic system always maintains optimal working condition under high pressure and high temperature conditions.

Why are original factory blind flanges so important?

Blind flanges serve as a “sealing barrier” for hydraulic systems, and their core functions include:
1. Absolute sealing: Achieves zero-leakage sealing at the hydraulic pump interface, maintaining stable system pressure.
2. Contamination Protection: Effectively prevents dust, moisture, and other contaminants from entering the hydraulic system.
3. Pressure and temperature resistance: Can withstand a maximum working pressure of 42MPa and a temperature range of -20℃ to 120℃.
4. Convenient Maintenance: Optimized design makes installation and disassembly easier, improving maintenance efficiency by 40%.

[Professional Advice]

Before installation, thoroughly clean the sealing surface to ensure no impurities remain. It is recommended to use the original manufacturer’s sealing ring and tighten the bolts to the standard torque requirements. Avoid collisions and scratches during storage to keep the sealing surface intact. Perform regular maintenance and inspections, especially increasing the frequency under harsh operating conditions. After disassembly, promptly install protective devices to prevent contamination of the exposed interfaces.
