Decommissioning

Preparing for operation

16.1
For commissioning fill the pump with operating
liquid up to middle of shaft. This may be
effected through suction,
operating liquid pipe.
CAUTION
16.1.1.1.1 Dry run of the pump shall be
avoided by all means. Otherwise any
warranty for
resulting including
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
additional 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
automatically (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
congealing 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.
