Product Overview
This high-performance repair seal kit is professionally engineered for Danfoss PV22 axial piston hydraulic pumps, a mainstream model of Danfoss PV series heavy-duty hydraulic pumps widely used in mobile machinery and industrial hydraulic systems. The complete set is equipped with full sets of shaft seals, O-rings, gaskets, backup rings and all matched sealing components, fully meeting the demands of comprehensive overhaul and daily routine maintenance for PV22 pumps.
Manufactured with high-quality imported NBR nitrile rubber and FKM fluororubber as core sealing materials, this seal kit boasts excellent oil resistance, high-pressure resistance, wear resistance and anti-aging properties. It can be used as a direct replacement for original Danfoss sealing parts. The kit effectively solves common malfunctions such as external oil leakage, internal leakage and system pressure loss, and significantly prolongs the service life of PV22 hydraulic pumps operating under long-duration heavy load, high-frequency running and severe vibration conditions.

Key Selling Points
1. 100% Exact OEM Replacement.It is fully compatible with original Danfoss PV22 hydraulic pumps with standard OEM dimensions. No cutting, grinding or additional modification is required. The product supports quick direct installation for daily maintenance, field overhaul and emergency on-site repair, effectively reducing equipment downtime and labor costs.
2. High-Grade Imported Sealing Materials.The core sealing parts adopt high-performance FKM fluororubber and reinforced PTFE backup rings. The materials feature strong resistance to hydraulic oil corrosion, high temperature and fatigue deformation. It maintains stable and reliable sealing performance within the temperature range of -25°C to 125°C, adapting to various harsh working environments.
3. Superior High Pressure & Vibration Resistance.All sealing components have passed strict 38MPa high-pressure and long-cycle vibration simulation tests. It completely eliminates internal and external leakage of the pump body, stabilizes the pressure of the hydraulic system, and ensures stable flow output and reliable operation of PV22 pumps under heavy-load and high-vibration working conditions.
4. All-In-One Complete Repair Package.This kit contains all sealing accessories needed for full pump maintenance, including special seals for control assemblies. The integrated packaging unifies part management, simplifies inventory sorting, shortens the overall repair cycle and cuts down daily operation and maintenance costs of equipment.
5. Rigorous Factory Quality Inspection.Every seal kit is tested for air tightness, high-pressure durability and aging resistance before delivery. All products comply with original factory technical standards, providing a solid guarantee for the long-term stable operation of engineering machinery and industrial equipment.
6. Extensive Application Scope.Specially tailored for Danfoss PV22 hydraulic pumps, it is widely applied to multiple types of heavy-duty engineering, mobile and industrial equipment:
