 Housing of the pump and check all important components such as ball bearings,
mechanical seals and the vane. These should be replaced if they are damaged or
worn out.

Pressure test: A pressure test should be carried out after a repair or replacement.
The pressure should be 0.2MPa during 3 minutes without causing leakage or
'sweating'.
 Changing oil: The oil plug of the oil tank should be removed for this. Subsequently,
fill the tank up to 95% using 10# mechanical oil.
If you do not use the pump for a long time, it should be removed out of the water.
Let the pump operate for 10 minutes in clean water to remove hard sediments at the
inside and outside of the pump. Remove the plug from the socket, clean the outside
of the pump and let it dry thoroughly. Store the pump in a dry and safe place.

Clean the vane.
Use a thicker cable.
Rewind and overhaul the coil.
Put the float in a higher position.
Clean the inlet opening(s).
Straighten the hose or remove the
blockage.
Switch off the pump and move it
