Product Overview
This heavy-duty repair seal kit is specially engineered for Danfoss PV90R75 axial piston hydraulic pumps, a core model of Danfoss 90 Series high-pressure piston pumps widely used in mobile hydraulic systems. The complete kit includes all essential sealing components for full pump disassembly, overhaul and routine maintenance.
Manufactured with imported premium NBR nitrile rubber and FKM fluororubber combined with high-strength reinforced backup rings, this seal set delivers exceptional oil resistance, high-pressure endurance, wear resistance and anti-aging performance. It serves as a perfect direct OEM replacement for original Danfoss sealing parts. The kit effectively resolves typical pump failures such as external oil leakage, internal bypass leakage and system pressure loss, and greatly extends the service life of PV90R75 pumps operating under continuous heavy load, frequent impact and severe vibration working conditions.
