When a hydraulic pump starts leaking around the shaft, the oil seal is often one of the first components technicians inspect. But for professional hydraulic pump repair shops and parts distributors, the real problem is not simply replacing an oil seal. The challenge is finding a high-pressure oil seal that matches the pump application, maintains stable sealing performance, and helps reduce repeat repairs. Our PPS High-Pressure Oil Seal 60×110×7, manufactured from NBR, is desi

Introducing the UP0445E high-pressure oil seal, developed for Sauer Danfoss hydraulic pump applications and demanding hydraulic operating environments. In a hydraulic pump, the oil seal is more than a simple rubber component.
