Decommissioning

Preparing for operation

6.1
For commissioning fill the pump with operating
liquid up to middle of shaft. This may be ef-
fected through suction, discharge or operating
liquid pipe.
CAUTION
Dry run of the pump shall be avoided by all
means. Otherwise any warranty for any
consequences resulting including claims
for compensation of damages invalidate.
Check the direction of rotation. Wrong
direction of rotation leads to damages at
the pump.
V1/V6/V30/V55
In order to control the liquid level N, an addi-
tional valve in the operation liquid pipe may be
provided (see illustr. 4b).
V95 - 430
In order to control the liquid level N a valve
may be connected to the connection U
automatic discharge valve at this connection
controls and regulates the liquid level auto-
matically (illustr. 2a/4a).

If the decommissioning is made to effect
any works at the pump, the drive must be
secured so that it cannot be switched on.
When using the pump for hazardous gases, it
has to be rinsed thoroughly before opening. In
order to prevent that easily inflammable gases
will cause an explosive air/gas mixture, the
pump has to be rinsed sufficiently with inert
gas before opening it and before restarting it
after opening.
In case of danger of frost or danger of congeal-
ing of the ring liquid, pump and liquid separator
have to be emptied by withdrawing all plugs at
bottom. This is also applicable for a longer
shut-down period.
