2 Transportation and Storage
The RUVAC WH pumps are heavy machines and thus should only be lifted
using suitable lifting equipment tied to the eyes provided for this purpose.
The correct lifting is described in fig. 2.1. Serious injury can result if the pump
is dropped or not handled properly. Never lift the RUVAC when connected to
a forevacuum pump.
When the pump is removed from the shipping container it has to be secured
with suitable lifting equipment until it is safely bolted on either a vacuum flan-
ge or a rack that is stable enough to support the weight of the pump. If bol-
ted to a forevacuum pump or a rack, sufficient tilt resistance has to be
ensured.
When connecting or removing the pump, do not step under hoisted loads.
Notice safety information 0.1.
WH/WHU 4400 und 7000: Before transporting the pump always drain out
the oil (see Section 5.2). Screw the oil-drain plug with its gasket back in
and wipe any oil droplets off from the casing.
The pump should be transported and stored in a horizontal position (10°
max. tilt). Otherwise there is the danger that oil from the side chambers
may enter the pump chamber, even before the pump is filled with oil for the
first time.
WH/WHU 2500: The pumps are supplied filled with oil or PFPE. For this
reason they should, while being transported or shipped, not be subjected
to much tilting. Store the pumps only horizontally standing on their feet.
Storage
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 for-
get to remove this bag first.
Pumps having a filling of PFPE should be sealed off in a gas-tight manner
and vented with nitrogen
.
If there is the danger of frost, the cooling water must be drained, see
Section 4.3 Removing from Service.
You may use a water glycol mixture of up to 30 %.
