Record the basics
Start with the pump identity and operating context
- Pump model and serial number
- Run hours and service history
- Application, duty cycle, and process temperature
Example
Data Sheet
Rotary Vane Service Data Snapshot
Use the same service records every time so you can compare condition over time and spot drift early.
Capture condition data
Measure what changed before and after service
- Inlet vacuum / performance at load
- Motor current and running temperature
- Oil appearance, level, and carryover
What to inspect during service
Common service points for rotary vane pumps
Typical service work includes checking and replacing oil and filters as needed, inspecting vanes and seals, verifying bearings and drive components, and confirming that the pump can reach and hold the expected vacuum for the application.
Exact service intervals and acceptable readings vary by model, operating temperature, contamination level, and run hours. Always compare the data sheet with the OEM manual and the specific pump’s service history.
Why the data matters
Trend data is more useful than a single reading
A single measurement is only a snapshot. When you record the same values before and after service, you can tell whether a pump is stabilizing, drifting, or heading toward a repeat failure. That makes future troubleshooting faster and more accurate.
