The Berkeley M12337 grease seal is a replacement grease seal for the Berkeley B3ZR common parts group used by the B3ZRM and B3ZRMS configurations below. Match the existing seal and the pump catalog number before selecting the replacement.
These pump configurations use two M12337 grease seals per pump. That is the pump service requirement, not a two-piece package description. Check which positions need attention and confirm the order quantity for the repair; do not assume one seal replacement addresses both locations.
