Product Overview
This high‑performance repair seal kit is professionally developed for Danfoss H1P045 series variable displacement axial piston hydraulic pumps, with a displacement of 45cm³/rev. The kit contains complete shaft seals, O‑rings, gaskets, backup rings and wear rings for full pump overhaul and routine maintenance.
Adopting imported premium NBR nitrile rubber and FKM fluororubber as core materials, the seal set features outstanding oil resistance, high‑pressure resistance, wear resistance and aging resistance. It is a perfect direct replacement for original Danfoss seals. It effectively resolves common faults including external oil leakage, internal leakage and pressure drop, and extends the service life of H1P045 pumps under long‑term heavy‑load, high‑pressure and vibration working conditions.

Key Selling Points
1. 100% Exact OEM Replacement.Fully compatible with original Danfoss H1P045 hydraulic pumps, matching standard OEM part numbers precisely. No cutting or modification needed, supports quick direct installation for regular overhaul and emergency repair.
2. Premium Imported Sealing Material.Core sealing components use high‑performance FKM fluororubber, reinforced backup rings and PTFE wear rings. The materials resist hydraulic oil corrosion, high temperature and fatigue, and maintain stable sealing performance continuously within the temperature range of ‑20°C to 120°C.
3. High Pressure & Vibration Resistance.All parts pass strict 42MPa high‑pressure and vibration simulation tests. It eliminates internal and external leakage thoroughly, keeps hydraulic pressure stable, and guarantees consistent flow and power output of the pump under harsh working conditions.
4. Complete All‑in‑One Repair Kit.Equipped with all sealing accessories required for full pump maintenance, including special seals for valve plates and bearing assemblies. Integrated package simplifies parts management, shortens repair time 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 factory standards, delivering reliable long‑term operation for industrial and construction machinery.
6. Wide Application Scope.Suitable for Danfoss H1P045 hydraulic pumps equipped on various heavy‑duty and engineering equipment:
