If the liquid to be pumped is not warmer than 35°C?
It there is no air breach in the suction elements?
If the pump is full of water?
You might need to...
Clean up the filter of the suction hose.

Have you checked...
If connectors of the suction part are perfectly airtight?
If the suction hose is under at least 30cm of liquid?
If the suction hose is filled with liquid (meaning that anti-return

If the filter of the suction hose is not obstructed?
If the pump is full of water?
You might need to...
Check the level of the water to be pumped
Check the suction hose airtightness: fill the hose with water,
