🔍 Key Concepts

• Centrifugal purifier bowl construction – identify where paring devices (small stationary pump elements) are usually located in the bowl cross‑section • Difference between a locking ring (mechanical clamp) and a paring device/gasket (fluid handling or sealing components) • Flow path of oil/water through the upper vs. lower paring devices in this style of purifier

💭 Think About

• Look carefully at where label 'C' is pointing: is it on a fluid passage/inner pump element, or on an outer mechanical clamping piece that holds parts together? • Compare the position of 'C' with the labels down near the discharge area where the purified liquids leave the bowl—where would you expect the upper and lower paring devices to sit relative to the clean-oil and water outlets? • Ask yourself what kind of part would logically be a gasket in this location versus a locking ring or a pump lock – what shape and contact surfaces do you actually see?

✅ Before You Answer

• Verify whether paring devices in the illustration are located deep inside the bowl near the liquid outlets, not up on the outer rim of the cover • Check if the part at 'C' appears to be a metallic clamping ring or a soft sealing element (gasket) in the cross‑section hatch pattern • Confirm whether any other arrows in the figure are clearly pointing to the upper and lower paring devices, so you don’t pick a label that’s already used elsewhere for those parts
