Product Overview
This high-performance repair seal kit is engineered specifically for the Kawasaki K3V280DT tandem variable displacement axial piston hydraulic pump, a core power unit for heavy-duty excavators and mining machinery. It covers the full 560cc/rev displacement (2×280cc/rev) and contains all critical sealing components required for complete pump overhaul and maintenance.
Crafted from imported premium NBR nitrile rubber and FKM fluororubber with reinforced backup rings, the kit delivers exceptional oil resistance, high-pressure endurance, wear resistance, and thermal stability. It serves as a 100% direct OEM replacement for original Kawasaki seals, effectively resolving common failures like external oil leakage, internal seepage, and pressure drop, while extending the service life of K3V280DT pumps under extreme heavy-load, high-vibration operating conditions.

Key Selling Points
1. 100% Exact OEM Replacement.Fully compatible with the original Kawasaki K3V280DT hydraulic pump, matching standard OEM part numbers and dimensional tolerances precisely. No cutting, modification, or special tools required—supports quick direct installation for routine overhauls and emergency repairs, minimizing equipment downtime.
2. Premium Imported Sealing Materials.Core sealing components adopt high-performance FKM fluororubber and reinforced backup rings. These materials resist hydraulic oil corrosion, high-temperature aging, and mechanical fatigue, maintaining stable sealing performance continuously across the -20°C to 80°C temperature range. The reinforced backup rings prevent seal extrusion under extreme pressure, ensuring long-term reliability.
3. Extreme Pressure & Vibration Resistance.All parts undergo strict 39.2MPa high-pressure and vibration simulation tests, compliant with Kawasaki’s original factory standards. The kit thoroughly eliminates internal and external leakage, stabilizes hydraulic pressure output, and guarantees consistent torque and flow delivery of the K3V280DT pump under harsh mining and heavy-construction working conditions.
4. Complete All-in-One Repair Kit.Equipped with all sealing accessories required for full K3V280DT pump maintenance, including specialized seals for tandem pump connections and control valve components. The integrated package simplifies parts inventory management, shortens repair time by 30%, and reduces overall equipment operation and maintenance costs.
5. Strict Factory Quality Control.Every seal kit undergoes air tightness, high-pressure, and aging tests before delivery, with 100% inspection for critical components. All products comply with ISO 9001:2015 and Kawasaki’s original quality standards, ensuring reliable long-term operation for industrial and mining machinery.
6. Wide Application Scope.Designed for Kawasaki K3V280DT hydraulic pumps installed on ultra-large heavy-duty equipment:
