Example plate pump
1. Operating conditions
Standard construction
- For clean liquids, without abrasives, non-explo-
sive, non-aggressive for the pump materials,
with a maximum temperature of 90°C.
- Maximum permissible working pressure up to
10 bar.
- Installation in well ventilated location protected
from the weather with a maximum ambient tem-
perature of 40°C.
The electric data marked on the label are referred
to the nominal power of the motor.

2. Transportation
The safe movement of the equipment is
on the user responsability and any lif-
ting operation must be carried out by a
suitably trained and qualified personnel.
Raise the pump-motor unit slowly (fig.1), making
sure it does not move from side to side in an un-
controlled way, to avoid the risk of imbalance and
tipping up.
3. Installation
These pumps must be installed with the rotor axis
horizontal and feet downwards.
Place the pump as close as possible to the suction
source (with consideration given to the NPSH value).
Provide space around the pump for motor ventila-
tion, to allow for checking of shaft rotation, for fil-
ling and draining the pump and to allow for collec-
tion of the liquid to be removed.
