Operation

Never open the oil-fill or oil-drain screw in the presence of a vacuum or
while the pump is running. There is the danger that oil may squirt out.
The oil level for the shaft seal housing must always be visible in the oiler (see
fig. 4.1). The correct oil level is 1/3 of the height of the oil when the pump is
cold 1/2 of the height of the oiler when the pump is warm. Top up any oil as
required.
In case of operation with mineral oil we recommend our vacuum pump oil
LVO 100, in case of operation with synthetic oil we recommend LVO 210.
If it is required to top up oil very often, it is quite likely that a shaft seal is
faulty.
4.3 Shutdown and Storage
Close the valve between the Roots pump and the vacuum system. First
switch off the Roots pump, then the backing pump.
After working with corrosive gases, the system should be vented with dry
protective gas (e.g. N
2
) to prevent corrosion during standstill.
When shutting down the pump and removing it from the system, it is
advisable to seal the connecting flanges tightly.
Before removing pump from the vacuum system, disconnect it from the
mains supply. Note any contamination affecting the pump.
Comply with all safety regulations. Observe safety informations 0.2.
Zum Transportieren und Lagern der Pumpe beachten Sie bitte die Hinweise
in Abschnitt 2.
4.4 Changing from Vertical to Horizontal Flow
The RUVAC WA/WAUs are supplied as standard for vertical flow unless you
specifically request horizontal flow. Moreover, the pump may be converted
from one flow direction to the other.
For this proceed as follows:
Unscrew the sealing screws and drain out the oil from the side chambers
(see fig. 4.2). Drain the oil from the oiler (see section 5.3).
Seal off of the bottom opening with the closure screw and a seal which is in
perfect condition so that a vacuum-tight seal is attained again.
Unscrew the pump’s feet, turn the pump by 90° and as shown in figure 1.5
(dimensional drawing) fit the feet for the changed direction of pumping action.
The longitudinal axis of the pump must remain horizontal so that no residu-
al lubricant can flow from the side chambers into the pumping chamber.
