Where each walk sits in the schedule
- Base-mounted HVAC pump quarterly maintenance checklistquarterly
- Every quarter, walked with the rest of the mechanical-room equipment so the pump numbers are read against the gauges on the same visit. Run by: The mechanical tech on the quarterly mechanical-room round.
- Base-mounted HVAC pump annual maintenance checklistannual
- Once a year during a system shoulder period, when the pump can be locked out long enough to break the coupling and check alignment cold and hot. Run by: The mechanical service crew on the annual, with the pump locked out for the alignment and bearing work.
What most often fails on a base-mounted HVAC pump
- A mechanical seal weeping a steady drip called 'normal' until it floods the base and rusts the motor feet.
- Suction and discharge gauges read but never compared, so a clogging strainer starving the pump goes unnoticed until the flow drops off.
- Bearing noise logged as 'a little loud' visit after visit with no grease added and no temperature ever felt or measured.
- Coupling alignment 'eyeballed' at install and never re-checked, so a soft foot or thermal growth chews through seals and bearings on a cycle.
- Grout under the base cracked or the anchor bolts loose, letting the pump walk and throwing alignment off between services.
- VFD left in a hand or bypass mode after a past troubleshooting call, so the pump runs full speed and the drive's energy and soft-start are doing nothing.
Common questions
- Which base-mounted HVAC pump maintenance rounds do these checklists cover?
- Base-mounted HVAC pump quarterly maintenance checklist (quarterly): Every quarter, walked with the rest of the mechanical-room equipment so the pump numbers are read against the gauges on the same visit. Base-mounted HVAC pump annual maintenance checklist (annual): Once a year during a system shoulder period, when the pump can be locked out long enough to break the coupling and check alignment cold and hot.
- Who runs the base-mounted HVAC pump maintenance round?
