1 .  DELIVERY AND STORAGE
1 .1  Delivery

These  submersible  pumps  are  supplied  in  their  own 

original  packing  in  which  they  should  remain  until 

installation.

Avoid the pump to be bent when it is not packed, since 

this may cause the misalignment and the damage of the 

pump itself.

The loose data plate supplied with the pump should be 

fixed close to the electric control equipment.

The pump shall not be exposed to unnecessary impacts 

and crashes.

1 .2  Storage and Handling

Storage Temperature:

Pump: from -20°C to +60°C

The pump should not be exposed to direct sunlight.

If  the  pump  has  not  been  packed,  it  shall  be  stored 

horizontally,  adequately  supported,  or  vertically,  to 

prevent  the  misalignment  of  the  pump.  During  storage, 

the pump can be supported as shown in Fig. 1.
