Installations - Landustrie DCP22 Operation & Maintenance Manual

Installations:

For the DTP pumps in basic versions several installation options are possible.
These options will be explained, with focus on specific points of attention.
Installation "BWK"
This installation represents a permanent submerged installation using the header coupling" type
"BWK".
The pumps are suspended in horizontal position to the coupling.
Points of attention:
 Ensure a good free passage under the pump, at least identical
to the suction opening.
 Adjust start- and stop levels in such a way that the motor
will not make more than 20 starts per hour.
 Check that the motor is adequately cooled.
At full load conditions, at least 2/3 of the motor housing should
be submerged.
 The pump casing must stay under water to avoid air being
drawn in.
Installation "OWK"
This installation represents a permanent submerged installation using the guide bar coupling"
type "OWK050"
Points of attention:
 Ensure a good free passage under the pump, at least identical
to the suction opening.
 Check both the vertical and parallel position of the guide bars.
The maximum tolerance for the vertical position is ± 3
 The installation angle for the pump in case of installation or
taking out is important.
This angle (between pump and guide bar) is about 0
This angle can be adjusted by changing the position of the
hoisting cable.
 Adjust start- and stop levels in such a way that the motor will
not make more than 20 starts per hour.
 Check that the motor is adequately cooled.
At full load conditions, at least 2/3 of the motor housing should be submerged.
 The pump casing must stay under water to avoid air being drawn in.
