A magnetic-drive pump preventive maintenance schedule lists the checks and jobs done on the equipment at fixed intervals, how long each takes, and in what order of frequency, so problems are found before the magnetic-drive pump fails. This page gives the schedule used in the PlantOps360 task library for magnetic-drive pump (lless) pump), which follows common industry practice for general-purpose equipment. It is also searched for as mag drive pump, canned motor pump, sealless chemical pump, polypropylene pump.
The maker’s manual and your site safety procedures always come first where they differ. Intervals set by law differ by state.
Magnetic-drive pump preventive maintenance schedule and checklist
| How often | Task | Estimated time |
|---|---|---|
| Daily | Check for leaks; monitor flow and differential pressure; confirm no dry running | 5 min |
| Daily | Check bearing and containment shell temperature (if monitored) and for abnormal noise | 3 min |
| Weekly | Check flushing or circulation flow to the internal bearings and strainers | 10 min |
| Monthly | Check motor bearings and magnet coupling for rubbing noise | 15 min |
| Quarterly | Check internal bearing wear through the inspection or drain plug | 30 min |
| Half-yearly | Check motor and base fasteners; test dry-run, temperature and power protection | 45 min |
| Annual | Overhaul: inspect inner and outer magnets, rear casing, shaft, bearings and wear parts | 300 min |
Magnetic-drive pump maintenance frequency and yearly workload
At the estimated times, one magnetic-drive pump needs about 69 hours of preventive maintenance a year. The biggest single job is “Overhaul: inspect inner and outer magnets, rear casing, shaft, bearings and wear parts” at 300 minutes, done annual. Multiply by the number of units you have to see the workload for your plant.
| Frequency | Tasks | Time per round | Hours per year |
|---|---|---|---|
| Daily | 2 | 8 min | 48.7 h |
| Weekly | 1 | 10 min | 8.7 h |
| Monthly | 1 | 15 min | 3.0 h |
| Quarterly | 1 | 30 min | 2.0 h |
| Half-yearly | 1 | 45 min | 1.5 h |
| Annual | 1 | 300 min | 5.0 h |
What goes wrong on a magnetic-drive pump without preventive maintenance
- Dry running that destroys the internal bearings
- Magnet decoupling from overload or solids
- Containment shell damage
- Loss of flush flow to the bearings
What to watch between services
- Flow and differential pressure
- Containment shell temperature
- Flush or circulation flow
Safety and statutory notes for magnetic-drive pump maintenance
Sealless pumps are often used for hazardous fluids. Follow the isolation and draining procedure strictly, and never run them dry or against a closed valve.

Frequently asked questions
How often should a magnetic-drive pump be serviced?
In our schedule a magnetic-drive pump has 7 tasks: 2 daily, 1 weekly, 1 monthly, 1 quarterly, 1 half-yearly, 1 annual. The biggest job is “Overhaul: inspect inner and outer magnets, rear casing, shaft, bearings and wear parts”, which is done annual. Always follow the maker’s manual where it gives a different interval.
What is included in magnetic-drive pump preventive maintenance?
It covers routine checks and jobs such as “Check for leaks; monitor flow and differential pressure; confirm no dry running”, “Check bearing and containment shell temperature (if monitored) and for abnormal noise”, “Check flushing or circulation flow to the internal bearings and strainers”, up to the annual overhaul or inspection. The full list with times is in the table above.
How many hours of maintenance does a magnetic-drive pump need per year?
About 69 hours per unit per year at the estimated times in our library, including the daily checks done every day. Use it to plan workload, not as a benchmark.
Is there a free magnetic-drive pump maintenance checklist?
Yes. The table on this page is a ready checklist. The free preventive maintenance schedule generator turns it into a 12-month Excel schedule for your list of equipment, with monthly workload hours.
