Product Overview
This high-performance repair seal kit is engineered for Eaton 4623 series axial piston hydraulic pumps, widely used in medium-to-high pressure hydraulic systems. It covers main pump models with displacements ranging from 55cc to 160cc per revolution. The kit includes complete shaft seals, O-rings, gaskets, backup rings, and valve body sealing components, enabling full overhaul and routine maintenance of the pump.
Manufactured with imported premium NBR nitrile rubber and FKM fluororubber as core materials, the seal set delivers exceptional oil resistance, high-pressure resistance, wear resistance, and aging resistance. It serves as a direct OEM replacement for Eaton 4623 pump seals, effectively resolving common issues such as external oil leakage, internal leakage, and pressure drop. It extends the service life of Eaton 4623 pumps under continuous heavy-load, high-pressure, and fluctuating working conditions.

Key Selling Points
1. 100% Exact OEM Replacement.Fully compatible with original Eaton 4623 hydraulic pumps, matching standard OEM part numbers precisely. No cutting or modification required, supporting quick direct installation for scheduled overhauls and emergency repairs.
2. Premium Imported Sealing Material.Core sealing components adopt high-performance FKM fluororubber and reinforced backup rings. The materials resist hydraulic oil corrosion, high temperature, and fatigue, maintaining stable sealing performance within the -20°C to 120°C temperature range.
3. High Pressure & Durability.All components undergo strict 35MPa high-pressure and cycle simulation tests. Eliminates internal and external leakage, stabilizes hydraulic pressure, and ensures consistent flow and pressure output of the pump under harsh working conditions.
4. Complete All-in-One Repair Kit.Contains all sealing accessories for full pump maintenance, including specialized seals for control valves and end covers. The integrated package simplifies parts management, shortens repair time, and reduces overall equipment O&M costs.
5. Strict Factory Quality Control.Each seal kit undergoes air tightness, high-pressure, and aging tests before delivery. All products comply with original factory standards, ensuring reliable long-term operation for industrial and construction machinery.
6. Wide Application Scope.Suitable for Eaton 4623 hydraulic pumps equipped on various heavy-duty and engineering equipment:
