Suitability
This two-stage oil lubricated rotary vane vacuum pump can be used for the evacuation of a closed system.
The ambient and suction temperatures must be between 5 and 40°C. For temperatures outside this range please
contact your supplier. Amounts of water vapour may be handled. Water, other liquids, aggressive or inflammable
gases and vapours may not be handled.
The standard versions may not be used in hazardous areas. Special versions with Ex-proof motors can be supplied.
For all applications where an unplanned shut down of the vacuum pump could possibly cause harm to persons
or installations, then the corresponding safety backup system must be installed.
Handling and Setting up
Pumps that have reached operating temperature may have a surface temperature at special position of more than
70° C.
WARNING! Do Not Touch.
Oil filler port (H), oil sight glass (I), oil drain plug (K), gas ballast valve (U), filter housing (X
1
, X
2
), oil separator housing cover (Y),
cooling water inlet (C) and cooling water outlet (D) must all be easily accessible. The cooling air entries (E) and the cooling air
exits (F) must have a minimum distance of 20 cm from any obstruction. The discharged cooling air must not be re-circulated.
For maintenance purposes we recommend a space of 0.4 m in front of the filter housing and oil separator.
The VVB pumps can only be operated reliably if they are installed horizontally.
For installations that are higher than 1000 m above sea level there will be a loss in capacity. For further advice
please contact your supplier.
When installed on a solid base, the pumps may be installed without fixing down. If the pumps are installed on a base plate we
would recommend to fit anti vibration mounts. These range of vacuum pumps are almost vibration free in operation.
Installation
For operating and installation follow any relevant national standards that are in operation.
1. Vacuum connections at (A

)
➝
higher capacity and at (A

)
➝
lower capacity.
The air handled can be exhausted into the atmosphere through the exhaust port (B) or by utilising an exhaust pipe.
Long and/or small bore pipework should be avoided as this tends to reduce the capacity of the pump.
The exhaust port (B) must not be obstructed or partly obscured.
2. The lubricating oil (recommended brands see under servicing) can be put into the pump at the oil filler port (H) of the oil
separator housing, until the oil level shows at the upper mark of the oil sight glass (l). After filling make sure oil filler port is
closed.
3. The electrical data can be found on the data plate (N) or the motor data plate. The motors correspond to DIN/VDE 0530 and
have IP 54 protection and insulation class B or F. The connection diagram can be found in the terminal box on the motor.
Check the electrical data of the motor for compatibility with your available supply (voltage, frequency, permissible current
etc.).
