Product Overview
This high-performance repair seal kit is engineered specifically for the Kawasaki K3SP36B swash-plate axial piston pump, a widely used unit in compact excavators and construction machinery. It covers the dual-displacement design of 36 cm³/rev × 2 (total 72 cm³/rev) and contains all necessary sealing components for complete pump overhaul.
Crafted from premium imported NBR nitrile rubber and FKM fluororubber, the kit delivers exceptional oil resistance, high-pressure durability, wear resistance, and aging stability. It serves as a direct OEM replacement for original Kawasaki seals, effectively resolving external leakage, internal bypass, and pressure drop issues. Designed for long-term heavy-load operation, it extends the service life of K3SP36B pumps under harsh construction-site conditions.

Key Selling Points
1. 100% Exact OEM Replacement.Fully compatible with original Kawasaki K3SP36B hydraulic pumps, matching standard OEM part numbers precisely. No cutting or modification required, enabling quick direct installation for routine maintenance and emergency repairs. Ensures perfect fit and consistent performance with original equipment.
2. Premium Imported Sealing Material.Core sealing components adopt high-performance FKM fluororubber and reinforced backup rings. These materials resist hydraulic oil corrosion, high temperatures, and mechanical fatigue, maintaining stable sealing performance across the -20°C to 120°C operating range. The NBR components provide excellent elasticity and wear resistance for dynamic sealing surfaces.
3. High Pressure & Impact Resistance.All parts undergo strict 30MPa high-pressure and impact simulation tests. Effectively eliminates internal and external leakage, stabilizes hydraulic pressure, and ensures consistent flow output of the K3SP36B pump under heavy-load and frequent pressure-fluctuation conditions. Ideal for rigorous construction machinery applications.
4. Complete All-in-One Repair Kit.Includes every sealing accessory needed for full pump maintenance, including specialized seals for the integrated pilot pump and valve plate components. The integrated package simplifies parts management, reduces repair time, and lowers overall equipment operation and maintenance costs. No need to source individual seals separately.
5. Strict Factory Quality Control.Each seal kit undergoes air tightness, high-pressure, and aging tests before delivery. All products comply with Kawasaki’s original factory standards, ensuring reliable long-term operation for construction and industrial machinery. Every batch is traceable for quality assurance.
6. Wide Application Scope.Designed for Kawasaki K3SP36B main pumps equipped on various compact construction and engineering equipment:
