The best repair schedule begins before the truck arrives.
1. Record the operating point—not just the complaint
“It will not pull vacuum” is an observation, not a diagnosis. Capture suction and discharge pressure, motor load, speed, seal-liquid conditions and production rate at the same moment.
Tie the readings to a known operating state so startup or upset data is not mistaken for normal duty.
2. Document what changed
List recent maintenance, valve, process, piping and control changes. Note whether the loss was sudden or gradual and whether noise, vibration or leakage changed with it.
3. Prepare the decision path
Confirm who can authorize inspection, restoration, major scope changes and replacement evaluation. A documented approval path keeps teardown findings from sitting idle.
General industrial guidance only. Qualified personnel should review equipment design, process conditions and site risk before changes.
