1. Introduction to WIGAM high vacuum pumps

Wigam high vacuum pumps are rotary vane type and lubricated by oil injection, single and dual stage, complete
with gas ballast valve to remove residual condensable gases.
Each stage is equipped with a rotor mounted on a shaft, which is directly connected to the electric motor without
joint; in the dual stage pumps, the two rotors are connected to one another in series, in order to reach the best
vacuum possible.

Gas ballast valve

Wigam vacuum pumps are equipped with a gas ballast valve (*), to keep open for about 3 minutes during
evacuation; the gas ballast valve allows a good pump starting and prevents polluted vapors from condensing in
the lubricant.

2. Installation

The pump is supplied without oil charge; before its rst use, it is necessary to ll the pump with the correct quantity
and type of oil suggested by the manufacturer.

2.1 Oil lling

When lling the oil or checking the oil level, the pump must be turned off.
The pump is supplied without oil charge; before its rst use, it is necessary to ll the pumps with the correct quantity
and type of oil suggested by the manufacturer.
A different lubricant reduces the performances and can irreversibly damage its mechanical parts.
A bottle of 400cc mineral oil is supplied with the pump.
To ll the oil into the pump, proceed as follows:
a) unscrew the charging cap (situated on top of the pump)
b) slowly ll in the oil up to the middle of the sight glass (situated on the side of the pump)
c) screw the charging cap
To avoid excessive lling, we suggest to spill the oil into a graduated bottle rst; in this way it is easy to check the
correct quantity.
In case of excessive lling, it is necessary to empty the pump and repeat the oil lling procedure.
Do not pollute environment with the lubricant; it is a special waste and must be disposed of according
the the current regulations.

2.2 Suction connection

A shorter and wider hose (as well as a straight "path") reduces time to perform evacuation.
On request, the suction connection can be equipped with a solenoid valve (a solenoid valve is standard equipment on
model RV25B) to prevent the lubricant from owing back from the pump to the circuit in case of electric power cut.

2.3 Vapors discharge

The pump can run without any discharge connection; when large volume circuits must be evacuated or in case the
pump is frequently turned on and off, we suggest to replace the standard cap with an oil extracting lter complete
with an oil receiver; the oil discharged during functioning is collected by the lter and drops into the oil receiver.
Always let the pump discharge connection free; ist obstruction can cause dangerous overpressures
2.4 Electric connection
