Product Overview
This high-performance repair seal kit is professionally engineered for Danfoss PV23 axial piston hydraulic pumps, a key model of Danfoss PV series heavy-duty axial piston pumps widely deployed in mobile machinery and industrial closed-circuit hydraulic systems. The complete package includes full sets of shaft seals, O-rings, flat gaskets, backup rings, control piston seals and all matching sealing components, fully supporting comprehensive overhaul, routine maintenance and on-site repair for PV23 pumps.
Manufactured with imported premium NBR nitrile rubber and FKM fluororubber as core sealing materials, paired with reinforced PTFE backup rings, this seal kit features outstanding oil resistance, high-pressure resistance, wear resistance and anti-aging performance. It serves as a perfect direct replacement for original Danfoss sealing parts. The kit effectively solves common malfunctions including external oil leakage, internal leakage and system pressure drop, and greatly extends the service life of PV23 pumps operating under long-duration heavy load, high-frequency cycling and severe vibration working conditions.

Key Selling Points
1. 100% Exact OEM Replacement.Fully compatible with original Danfoss PV23 hydraulic pumps and precisely matched with standard OEM dimensions. No cutting, grinding or extra modification is required. It enables 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.Core sealing components adopt high-performance FKM fluororubber and reinforced PTFE backup rings. The materials deliver strong resistance to hydraulic oil corrosion, high temperature and fatigue deformation. It maintains stable and reliable sealing performance continuously within the temperature range of -28°C to 120°C, adapting to various harsh field working environments.
3. Superior High Pressure & Vibration Resistance.All sealing parts have passed strict 35MPa high-pressure and long-cycle vibration simulation tests. It thoroughly eliminates internal and external leakage of the pump body, stabilizes hydraulic system pressure, and ensures steady flow output and reliable operation of PV23 pumps under heavy-load, high-pressure and high-vibration working conditions.
4. All-In-One Complete Repair Package.The kit is equipped with all sealing accessories required 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 engineering and industrial equipment.
5. Rigorous Factory Quality Inspection.Every seal kit undergoes air tightness test, high-pressure durability test and aging test before delivery. All products comply with original factory technical standards, providing long-term stable operation guarantee for engineering machinery and industrial hydraulic equipment.
6. Extensive Application Scope.Specially designed for Danfoss PV23 hydraulic pumps, widely used on various heavy-duty engineering, mobile and industrial equipment:
