The correct answer is C) water flingers. Water flingers are used to keep water leaking from a pump packing gland away from the bearing housing. The water flingers are designed to create a centrifugal force that throws the leaking water away from the bearing, preventing it from entering and damaging the bearing. This is an important design feature to maintain the proper lubrication and operation of the pump's bearings. The other options are incorrect because: A) shaft sleeves do not actively divert water, B) water seals are used to prevent water from entering in the first place, and D) lantern rings are used to distribute the packing material, not to divert water.
