Product Overview
This high-performance repair seal kit is engineered specifically for Kawasaki K3V140 series axial piston hydraulic pumps, including K3V140DT, K3V140DTP and K3V140S models with a displacement of 140cm³/rev. The kit contains a full set of shaft seals, O-rings, gaskets, backup rings and valve plate sealing components, supporting complete overhaul and maintenance of the pump.
Constructed with premium imported NBR nitrile rubber and FKM fluororubber (Viton) as core materials, the seal kit delivers exceptional oil resistance, high-pressure resistance, wear resistance and aging resistance. It serves as a direct OEM replacement for original Kawasaki seals, effectively resolving common issues such as external oil leakage, internal leakage and pressure drop, and extending the service life of K3V140 pumps under long-term heavy-load and high-frequency vibration conditions.

Key Selling Points
1. 100% Exact OEM Replacement.Fully compatible with original Kawasaki K3V140 hydraulic pumps, matching standard OEM part numbers precisely. No cutting or modification required, enabling quick direct installation for routine overhaul and emergency repair. It fits seamlessly with K3V140DT, K3V140DTP and K3V140S models.
2. Premium Imported Sealing Material.Core sealing components adopt high-performance FKM fluororubber (Viton) and reinforced backup rings. The materials resist hydraulic oil corrosion, high temperature and fatigue, maintaining stable sealing performance continuously within the temperature range of -35°C to 120°C. The shaft seal uses a multi-lip design to enhance dustproof and leakage-proof capabilities.
3. High Pressure & Vibration Resistance.All parts undergo strict 35MPa rated pressure and 39.2MPa peak pressure tests, as well as vibration simulation tests for construction machinery working conditions. It thoroughly eliminates internal and external leakage, maintains stable hydraulic pressure, and guarantees consistent flow and power output of the pump under harsh working conditions such as frequent start-stop and heavy-load operation.
4. Complete All-in-One Repair Kit.Equipped with all sealing accessories required for full pump maintenance, including special seals for the regulator and valve plate components. The integrated package simplifies parts management, shortens repair time by 30% compared to scattered parts procurement, 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. All products comply with original Kawasaki factory standards, with dimensional tolerance controlled within ±0.01mm, delivering reliable long-term operation for construction machinery.
6. Wide Application Scope.Suitable for Kawasaki K3V140 hydraulic pumps equipped on various heavy-duty construction machinery:
