Pump not pumping water

The LEO APm37 pump may not be pumping water due to the following reasons:
1. Water level is too low – adjust the installation height of the pump. 2. Suction pipe leakage – check and seal joints of the inlet pipelines. 3. Ice in the pipeline or chamber – melt the ice before starting the pump. 4. Incorrect pump type – use a suitable pump for the application. 5. Inlet pipeline is too long or has too many bends – shorten and use correct diameter pipe. 6. Inlet pipeline, filter screen, or pump chamber is blocked – clean out any foreign materials or sundries. 7. Impeller is jammed or overloaded – clear sundries and operate under rated flow. 8. Motor issues (e.g., intermittent operation or burned stator winding) – check grounding, cables, and replace winding coils if needed. 9. Air in the pump chamber – fill the pump chamber with clean water and discharge air before starting.
Also, if no water is discharged after 5 minutes, turn off the pump, re-fill water, and check for inlet pipeline leaks.
