Process Pump Seal and Guard Inspection

The process pump seal is inspected at rest, locked out and isolated, with the flange still made up. The technician writes the as-found reading and compares it with the last one on the asset. Do not break a flange or live-adjust a seal under pressure. Anything past that line belongs to the site's own procedure, the OEM manual, or a permit. This is the inspection ChatterFix schedules. It is not itself permission to go further.

The Procedure

The steps ChatterFix schedules for this PM. Every step is a checkable item on the work order — a technician can speak their way through it without touching a keyboard.

  1. With the pump locked out and isolated, inspect the seal for leakage at rest
  2. Check the bearing housing temperature history and the coupling guard
  3. Confirm the baseplate bolts and the oil level if the design has a sight glass
  4. Do not break a flange or open the process from this work order
  5. Write a leak as a finding. Do not live-adjust a seal under pressure

Why This PM Exists

What Skipping It Looks Like

A weep gets a wrench while the pump is on line, and the finding never gets written. The round still closes, the number never lands on the asset, and the next person inherits a guess. Do not break a flange or live-adjust a seal under pressure.

Setting the interval

Monthly. A leak is a finding. It is not a live adjustment. An as-found reading outside the limit the site already published is a finding. It does not become a new setpoint on this work order.
