Product Overview
This professional heavy-duty repair seal kit is exclusively developed for Danfoss PV90R55 axial piston hydraulic pumps, a core model of Danfoss 90 Series hydrostatic drive units. It is fully compatible with PV90R55 and the counterpart model PV90L55, covering full overhaul and routine maintenance requirements for 55cc/rev displacement pumps.
The kit integrates complete sealing components including shaft seals, dust seals, O-rings, gaskets, backup rings and internal component seals. Adopting imported premium NBR nitrile rubber and FKM fluororubber as core raw materials, it delivers excellent oil resistance, high-pressure resistance, wear resistance and anti-aging performance. As a direct OEM replacement part, it effectively resolves typical failures such as external oil leakage, internal seepage and system pressure loss, and extends the service life of PV90R55 pumps under long-duration heavy-load, high-frequency vibration and harsh outdoor working conditions.

Key Selling Points
1. 100% Exact OEM Compatibility.Precisely matched with the original size and installation standard of Danfoss PV90R55 pumps. It conforms to official OEM part specifications completely, no cutting, grinding or modification is required. The kit supports rapid direct installation for regular maintenance and on-site emergency repair, which greatly improves maintenance efficiency.
2. High-Grade Imported Sealing Materials.Key sealing parts adopt high-performance FKM fluororubber, combined with reinforced backup rings. The materials feature strong resistance to hydraulic oil corrosion, high temperature and fatigue deformation. It maintains stable and reliable sealing performance continuously within the wide temperature range of -35°C to 125°C, adapting to complex ambient temperatures of construction and agricultural sites.
3. Superior High Pressure & Vibration Resistance.All components have passed strict 42MPa high-pressure endurance test and mechanical vibration simulation test. It thoroughly eliminates internal and external leakage of the hydraulic pump, stabilizes system working pressure, and ensures continuous and stable flow and power output of PV90R55 pumps under severe working conditions.
4. All-In-One Complete Repair Kit.Equipped with all sealing accessories needed for full pump overhaul, including special dust-proof and wear-resistant seals for shaft ends. The integrated package unifies parts management, avoids missing individual accessories during repair, shortens downtime and reduces the overall operation and maintenance cost of equipment.
5. Rigorous Factory Quality Inspection.Every seal kit undergoes air tightness test, high-pressure leakage test and aging test before delivery. All products comply with Danfoss original factory quality standards, providing long-term reliable operation guarantee for engineering and mobile machinery.
6. Extensive Application Scope.Widely applicable to Danfoss PV90R55 hydraulic pumps equipped on various heavy-duty mobile equipment:
