Question 281Motor Plants - Assistant Engineer

The correct answer is A) upper locking ring. The device labeled 'C' in the illustration MO-0112 is the upper locking ring, which is a component used to secure the upper paring device in place. The upper locking ring is responsible for keeping the upper paring device stationary and preventing it from moving during operation. The other answer choices are incorrect because: B) lower paring device refers to a different component, C) upper paring gasket is a separate sealing component, and D) pump lock is not a term associated with the device shown in the illustration.
