Product Overview
This premium repair seal kit is specially engineered for Danfoss PV90M75 axial piston hydraulic motors, a core model of Danfoss Series 90 hydrostatic drive units. It is fully applicable to the 75cc/rev displacement version and covers the mainstream configurations of PV90M series motors. The complete kit includes shaft seals, O-rings, gaskets, backup rings, piston seals and all auxiliary sealing components required for full disassembly, overhaul and routine maintenance.
Adopting high-quality imported NBR nitrile rubber and FKM fluororubber as primary sealing materials, matched with reinforced anti-extrusion backup rings, this seal kit delivers excellent oil resistance, extreme pressure resistance, wear resistance and long-term aging resistance. It serves as a direct OEM replacement for original Danfoss sealing parts. The kit effectively resolves typical failures such as external oil leakage, internal leakage and system pressure loss, and extends the service life of PV90M75 motors operating under continuous heavy load, frequent pressure impact and severe vibration working conditions.

Key Selling Points
1. 100% Direct OEM Replacement.Perfectly matched with original Danfoss PV90M75 hydraulic motors and standard OEM dimensions. No cutting, grinding or modification is needed. It supports fast on-site installation for regular maintenance, breakdown repair and emergency replacement, which greatly improves maintenance efficiency.
2. High-Grade Imported Sealing Materials.Core sealing parts adopt high-performance FKM fluororubber and reinforced backup rings. The materials resist erosion of various mineral-based hydraulic oils, high temperature fatigue and extrusion damage. It maintains stable and reliable sealing performance throughout the full temperature range of -30°C to 120°C, adapting to diverse harsh ambient environments.
3. Superior High Pressure & Impact Resistance.All components have passed strict 42MPa high-pressure durability and vibration simulation tests. It thoroughly eliminates internal and external leakage of the motor, stabilizes system working pressure, and ensures stable torque, rotating speed and power output of PV90M75 motors under pressure impact and heavy-load operation.
4. Integrated Full-Set Repair Configuration.The kit is equipped with all sealing parts required for complete motor overhaul, covering main shaft, piston, valve assembly and joint sealing positions. The integrated packaging unifies part management, avoids missing accessories during maintenance, shortens equipment downtime and reduces overall operation and maintenance costs.
5. Rigorous Factory Quality Inspection.Every seal kit undergoes air tightness test, high-pressure cycle test and aging test before delivery. All products comply with Danfoss original factory technical standards, providing long-term stable operation guarantee for engineering and mobile machinery.
6. Extensive Application Scope.Compatible with Danfoss PV90M75 motors installed on a wide range of heavy-duty mobile equipment, including:
Welcome to HOVOO, a Chinese seal factory. Production of PU, Rubber and PTFE seals. The seals include O-ring, piston seal, rod seal, Gray ring and gas seal.
