Product Overview
This high‑performance repair seal kit is specifically designed for Danfoss MPT046 series tandem axial piston hydraulic pumps (Series 40, M46 frame), with a nominal displacement of 46cc/rev. The kit includes complete shaft seals, O‑rings, gaskets, backup rings, wear rings and all critical sealing components, enabling full pump overhaul and routine maintenance.
Built with imported premium NBR nitrile rubber and FKM fluororubber as core materials, the seal set delivers outstanding oil resistance, high‑pressure resistance, wear resistance and aging resistance. It is a direct OEM replacement for original Danfoss seals, effectively solving common issues such as external oil leakage, internal leakage and pressure drop. It extends the service life of MPT046 pumps under long‑term heavy‑load, high‑pressure and high‑speed operating conditions.

Key Selling Points
1. 100% Exact OEM Replacement.Fully compatible with original Danfoss MPT046 tandem pumps, precisely matching standard OEM part numbers. No cutting or modification required, supporting quick direct installation for regular overhaul and emergency repair.
2. Premium Imported Sealing Material.Core sealing components adopt high‑performance FKM fluororubber, reinforced backup rings and PTFE wear rings. The materials resist hydraulic oil corrosion, high temperature and fatigue, maintaining stable sealing performance within the temperature range of -25°C to 120°C.
3. High Pressure & Speed Resistance.All components undergo strict 38.5MPa high‑pressure and 4000r/min high‑speed simulation tests. It thoroughly eliminates internal and external leakage, stabilizes hydraulic pressure, and ensures consistent flow and power output of the pump in harsh environments.
4. Complete All‑in‑One Repair Kit.Comes with all sealing accessories needed for full pump maintenance, including dedicated seals for valve plate and bearing assembly. The integrated package simplifies parts management, shortens repair time and reduces overall equipment operation and maintenance costs.
5. Strict Factory Quality Control.Each seal kit passes 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 Danfoss MPT046 hydraulic pumps equipped on various heavy‑duty and engineering equipment:
