Engineering · Auxiliary — Purifier vs Clarifier
The difference between operating a centrifuge as a purifier versus a clarifier is that a clarifier:
- ARemoves mainly solids, runs without a water seal, and uses a sealing ring in place of a gravity disc✓ Correct
- BRemoves only water and uses a water seal
- CHeats the oil to a higher temperature
- DOperates at a much lower bowl speed
Explanation
A purifier separates water and solids and needs a water seal (gravity disc sized to the oil). A clarifier removes solids/sludge from oil with little water present, runs with no water seal, and fits a sealing (blank) ring instead of a gravity disc.
