Pumps with castors
Due to the castors which have been fitted, the LEYVAC must only be
installed on a level surface capable of carrying the weight of the pump as
otherwise there exists the danger of the pump rolling away. The pump must
also only be moved on level surfaces.
Moving the pump on slopes or ramps is not allowed!
The pump must only be transported using a crane.
At the installation site, use all four adjustable feet for aligning thereby securing
the unit from rolling away and thus taking away the load from the castors.
Storage
Store the pumps only horizontally standing on their feet.
When storing the pump for a longer period of time (> 2 weeks) the flanges
should be sealed off with a piece of foil. Place a bag with desiccant in the
pump chamber, if required. Before operating the pump once more do not
forget to remove this bag first.
Due to the PFPE filling pumps should be sealed off in a gas-tight manner and
vented with nitrogen.
The cooling jacket is filled with a water glycol mixture, which is cold resist-
ant up to -10 °C.
If there is the danger of frost, the cooling water for the external water cir-
cuit must be drained, see Section 4.4 Removing from Service
