Circulating Pump Maintenance Checklist
Keep heating and chilled water moving efficiently — pump operation, seal and bearing checks, speed-control verification, flow confirmation, and leak inspection.
What is a circulating pump maintenance checklist?
A circulating pump maintenance checklist is a structured list of the 10 preventive maintenance tasks — covering visual, functional and record-keeping checks — that keep a circulating pump running safely and reliably. It groups routine checks by frequency, from daily inspections to annual servicing, so FM teams and building engineers can plan and evidence preventive maintenance.
Core circulating pump checks
- Check for leaks at the seal, gland, and connections
- Confirm the pump runs and, on duty/standby sets, that changeover works
- Record currents, flows, changeover, and any repairs in the log
What is a circulating pump?
A circulating pump moves heating or chilled water around a building's distribution circuits, from boilers and chillers to terminal units. Often arranged as duty/standby pairs, modern circulators use variable speed (EC or inverter) control to match flow to demand and save energy. Reliable circulation is fundamental — a failed pump means no heating or cooling to the served area. Maintenance covers pump operation and changeover, seals and bearings, the speed control and its settings, flow verification, and electrical checks, keeping circulation reliable and efficient.
This checklist is one of 25 in our plumbing and water system maintenance checklists, covering pressurisation units, booster sets, storage tanks, TMVs and water treatment — pressure, hygiene and legionella control.
Typical Circulating Pump maintenance checklist
A practical starting point for planned preventive maintenance. Always refer to the manufacturer's O&M manual and site-specific requirements.
Visual Checks
- Check for leaks at the seal, gland, and connections
- Inspect isolation valves, strainers, and any anti-vibration mounts
Functional Checks
- Confirm the pump runs and, on duty/standby sets, that changeover works
- Listen and feel for bearing noise, vibration, and overheating
- Verify variable speed control operates and is set correctly
- Confirm flow and differential pressure are within design
- Check the motor current against rated values
- Verify the pump is venting and free of air locks
- Check electrical connections, isolation, and controls
Record Keeping
- Record currents, flows, changeover, and any repairs in the log
