BAFSL1SF‑type high‑pressure rotary shaft seal, dimension 55*78*8, material Viton(FKM).   Compatible Pump Models This replacement shaft seal is compatible with Kawasaki hydraulic pump K5V140, widely used on excavator heavy equipment.

Medium pressure seals, such as the BABSL, can be used in many applications including pumps and motors in hydro-units, mechanical power transmission gearboxes, and 2-stroke engines. However in conventional seal designs, as pressure increases the seal life dramatically decreases due to atypical seal wear that is caused by pressure distortion of the seal lip geometry and increased friction at the contact point. The BABSL minimizes those problems over a wide range of operating conditions.
