Product Overview
This premium repair seal kit is professionally engineered for Danfoss PV20 series axial piston hydraulic pumps, a classic model of Sauer Danfoss Series 20 hydrostatic drive units. It fits full standard displacement variants of the PV20 range and contains a complete set of sealing components for full pump overhaul and routine maintenance.
The seal kit adopts imported high-quality NBR nitrile rubber and FKM fluororubber as core sealing materials, paired with reinforced backup rings. It delivers excellent oil resistance, high-pressure endurance, wear resistance and anti-aging performance. As a direct OEM replacement for original Danfoss sealing parts, it effectively resolves common failures including external oil leakage, internal leakage and system pressure loss. It ensures stable operation and extends the overall service life of PV20 pumps under long-duration heavy-load, continuous vibration and harsh working environments.

Key Selling Points
1. 100% Exact OEM Replacement.Fully compatible with original Danfoss PV20 series hydraulic pumps and perfectly matches standard OEM dimensions and part numbers. No cutting, grinding or extra modification is required. It supports rapid direct installation for routine maintenance and on-site emergency repair, greatly reducing equipment downtime.
2. Premium Imported Sealing Materials.Core sealing components adopt high-performance FKM fluororubber and reinforced backup rings. The materials resist hydraulic oil corrosion, high temperature and fatigue deformation. It maintains stable and reliable sealing performance continuously within the wide temperature range of -25°C to 125°C, adapting to complex ambient conditions of construction and industrial sites.
3. Superior High Pressure & Vibration Resistance.All components have passed strict 350bar high-pressure and long-term vibration simulation tests. The kit thoroughly eliminates internal and external leakage, stabilizes hydraulic system pressure, and guarantees consistent flow and power output of PV20 pumps under severe working conditions. It is specially optimized for the vibration characteristics of mobile engineering machinery.
4. Complete All-in-One Overhaul Kit.Integrates all sealing accessories required for full disassembly and overhaul of the PV20 pump, including dedicated seals for control valves and charge pumps. The integrated packaging unifies parts management, simplifies maintenance procedures, shortens overall repair time and effectively cuts equipment operation and maintenance costs.
5. Strict Factory Quality Control.Every finished seal kit undergoes air tightness testing, high-pressure durability testing and aging resistance testing before delivery. All products fully comply with Danfoss original factory technical standards, providing long-term reliable operation guarantee for industrial and engineering equipment.
6. Wide Application Scope.Suitable for Danfoss PV20 hydraulic pumps equipped on diverse heavy-duty machinery and industrial equipment:
