Question 276Motor Plants - Assistant Engineer

The correct answer is D) centripetal pump chamber cover. The device labeled "B" in the illustration MO-0112 is the centripetal pump chamber cover. This is the cover that encloses the centripetal pump, which is a type of pump used in various marine applications, including in the US Coast Guard. The centripetal pump chamber cover helps to protect and enclose the internal components of the pump. The other answer choices are incorrect because they do not accurately describe the device labeled "B" in the given illustration. The upper ring chamber, set of regulating rings, and comminuting device are different components that are not depicted in this particular illustration.
