Product Overview
This heavy-duty repair seal kit is professionally engineered for Danfoss PV90R180 variable displacement axial piston hydraulic pumps, a core model of Danfoss Series 90. It covers full maintenance and overhaul requirements for the 180cc/rev displacement unit. The complete kit includes shaft seals, O-rings, gaskets, backup rings, piston seals and all auxiliary sealing components for full pump disassembly and reassembly.
Manufactured with imported premium NBR nitrile rubber and FKM fluororubber as core sealing materials, this seal set delivers excellent oil resistance, extreme pressure resistance, wear resistance and long-term anti-aging performance. It serves as a perfect direct OEM replacement for original Danfoss sealing parts. The kit effectively resolves common failures such as external oil leakage, internal leakage and system pressure loss, and extends the service life of PV90R180 pumps operating under continuous heavy load, high pressure and harsh vibration working conditions in engineering and mobile machinery.

Key Selling Points
1. 100% Exact OEM Replacement.Fully compatible with original Danfoss PV90R180 hydraulic pumps, strictly matched with standard OEM dimensions and part numbers. No cutting, grinding or modification is required. It supports fast direct installation for routine overhaul, field maintenance and emergency on-site repair, greatly improving maintenance efficiency.
2. High-Grade Imported Sealing Materials.Core sealing parts adopt high-performance FKM fluororubber and thickened reinforced backup rings. The materials feature strong resistance to hydraulic oil corrosion, high temperature fatigue and mechanical abrasion. It maintains stable and reliable sealing performance throughout the full temperature range of -40°C to 120°C, adapting to severe temperature changes in outdoor working scenarios.
3. Outstanding High Pressure & Vibration Resistance.All sealing components have passed strict 420bar continuous high-pressure and long-duration vibration simulation tests. It thoroughly eliminates internal and external leakage of the pump body, stabilizes system hydraulic pressure, and ensures consistent flow and power output of PV90R180 pumps under long-term high-load and impact working conditions.
4. Complete All-in-One Overhaul Kit.Equipped with all sealing accessories required for full pump maintenance, including special seals for piston assemblies and control mechanisms. The integrated package unifies all spare parts, simplifies inventory and parts management, shortens overall equipment downtime, and effectively reduces the comprehensive operation and maintenance cost of machinery.
5. Rigorous Factory Quality Inspection.Every seal kit undergoes air tightness test, high-pressure endurance test and aging test before delivery. All products comply with Danfoss original factory technical standards, providing stable and long-lasting operation guarantee for various heavy-duty machinery.
6. Extensive Application Scope.Specially designed for Danfoss PV90R180 pumps widely equipped on heavy-duty engineering, agricultural and mining equipment:
