🔍 Key Concepts

• Trace the oil inlet line (usually labeled and shown in brown) from the storage/source all the way to the separator bowl. • Identify any pump symbol in that inlet line and note whether it is mechanically connected to the separator or drawn as a separate unit. • Recall what the paring disc in a purifier normally does (discharge side vs. suction side).

💭 Think About

• Follow the oil inlet piping on the diagram: where does pressure to move the oil actually come from? • Does the purifier bowl itself show any device that would create suction on the inlet, or is there a dedicated piece of equipment in the line that does that? • Is the paring disc typically associated with taking in oil or with discharging separated liquids under pressure?

✅ Before You Answer

• Verify which item on the drawing is marked or symbolized as a pump on the oil inlet line. • Confirm whether that pump is shown as part of the separator casing/shaft or as a separate, stand‑alone unit in the piping. • Double-check that the paring disc shown is on the outlet side and not in the suction line before choosing your answer.
