Semi-Annual Recirculating Pump Maintenance Checklist

This semi-annual preventive maintenance checklist guides technicians through servicing a close-coupled recirculating pump. It outlines required tools and materials, key safety steps such as lockout/tagout, and detailed procedures: cleaning the pump casing and motor vents, inspecting wiring and controls for overheating or damage, tightening base bolts, draining the housing, checking suction and discharge performance, cleaning strainers, cycling isolation valves, and removing tags before startup. It includes operational testing for vibration, check valve action, shaft seal leakage, flange and fitting leaks, and recording inlet and outlet pressures before returning the unit to service. Use it to standardize maintenance and log results.
