Question 1038 Deck Safety

The correct answer is C) Water flinger. A water flinger, also known as a slinger ring or thrower ring, is a device designed to prevent water from running along the shaft of a leaking centrifugal pump from entering the shaft bearing. As the shaft rotates, the water flinger uses centrifugal force to throw the water away from the bearing, preventing it from reaching and potentially contaminating the bearing. This helps to maintain the proper lubrication and operation of the bearing, which is critical for the pump's reliable performance. The other options, such as a drain hole, shaft seal, or lantern ring, do not specifically address the issue of water entering the bearing from a leaking pump shaft.
