Product Overview
This professional high-performance repair seal kit is specially engineered for Danfoss PV90M55 axial piston hydraulic motors, a core model of Danfoss 90 Series fixed displacement motors. It fully supports complete overhaul and routine maintenance for PV90M55 motors with displacement of 55cc/rev, covering all standard configurations of this model series.
The kit integrates complete shaft seals, O-rings, gaskets, backup rings and all auxiliary sealing components. It adopts imported high-quality NBR nitrile rubber and FKM fluororubber as main sealing materials, delivering excellent oil resistance, high-pressure resistance, wear resistance and anti-aging performance. As a reliable direct replacement for original Danfoss sealing parts, this kit effectively solves typical motor failures such as external oil leakage, internal leakage and system pressure loss. It greatly extends the service life of PV90M55 motors operating under continuous heavy load, frequent startup and strong vibration working conditions for engineering and mobile machinery.

Key Selling Points
1. 100% Exact OEM Replacement.Fully compatible with original Danfoss PV90M55 hydraulic motors and strictly matched with standard OEM part numbers. No cutting, grinding or extra modification is required. It supports fast direct installation for daily maintenance, field overhaul and emergency on-site repair, which greatly improves maintenance efficiency.
2. Premium Imported Sealing Materials.Core sealing components are made of high-performance FKM fluororubber and reinforced backup rings. The materials feature outstanding resistance to hydraulic oil corrosion, high temperature and fatigue deformation. It maintains stable and reliable sealing performance throughout the wide temperature range of -35°C to 125°C, adapting to complex outdoor working environments.
3. Excellent High Pressure & Vibration Resistance.All sealing parts have passed strict 42MPa high-pressure endurance test and mechanical vibration simulation test. It thoroughly suppresses internal and external leakage of the motor, stabilizes system hydraulic pressure, and ensures stable torque and power output of PV90M55 motors under harsh working conditions such as heavy load, impact and long-term continuous operation.
4. All-in-One Complete Repair Kit.The package contains all sealing parts required for full motor maintenance, including dedicated seals for built-in parking brake structure. The integrated collocation simplifies spare parts management, shortens overall equipment downtime and effectively reduces daily operation and maintenance costs of machinery.
5. Rigorous Factory Quality Control.Every seal kit undergoes air tightness test, high-pressure durability test and aging test before delivery. All products are manufactured in accordance with Danfoss original factory standards, providing long-term stable operation guarantee for industrial and construction machinery.
6. Wide Application Scope.Designed for Danfoss PV90M55 hydraulic motors widely equipped on various heavy-duty mobile and engineering equipment:
