1. DELIVERY AND STORAGE
1.1 DELIVERY
Page
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 equip-
ment.
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 sun-
light.
If the pump has not been packed, it shall be sto-
red horizontally, adequately supported, or
vertically, to prevent the misalignment of the
pump. During storage, the pump can be supported
as shown in fig. 1.
If the pump is not used in vertical position, both the
pump side and the motor side must be supported.
Note that the centre of gravity will vary according
to the pump type.
2. GENERAL DATA
2.1 GENERAL DESCRIPTION
The submersible pumps are multistage pumps
working with counterclockwise rotation direction
(observing from the delivery side) directly coupled
to special submersible motors (according to NEMA
standards).
