5
External mechanical stresses and vibrations must not be transmitted to the pump. Only use
flexible vacuum hoses for connecting Rotary vane pumps.
The pump should not be used to suck up fluids. Lay the exhaust pipe so that it slopes
downwards, so allowing condensate to flow out of the pump. Collect the condensate and
dispose of it in an environmentally compatible manner.
Maintain a space of least 20 cm between the pump and adjacent parts in order to enable
the pump to cool.
CAUTION!
Solid particles in the pumping medium impair the pumping action and can lead to
damage. Prevent solid particles penetrating into the pump!
2.4 Hazardous Substances
CAUTION!
The operating company bears the responsibility for the use of the rotary vane pump.
Hazardous substances in the gases to be pumped can cause personal injuries and property damage.
Pay attention to the warning notices for handling hazardous substances.
The local regulations apply in foreign countries.
Combustible and explosive Gases
Examine before switching on whether that can form gas combustible gas/air mixtures which can be
promoted! Consider the regulations of the guideline 1999/92/EC.
It is not permitted to pump gases that are combustible or prone to explosion.
Aggressive gases
The Rotary vane pumps are not certified according to ATEX directive 2014/34/EU.
Poisonous gases
Use a separator when pumping poisonous or harmful gases. Prevent such substances from leaking
out of the appliance or pump. Treat these substances according to the applicable environmental
protection regulations.
Test the strength and leak-tightness of the connecting lines and the connected apparatus. Prevent
environmental poisons, e.g. mercury, getting into the Rotary vane pumps.
2.5 High Temperatures
The rotary vane pump may heat up as a result of the temperature of the gas being pumped and
through intrinsic heating. In dependence on the operation mode, the casing temperature can reach
90 °C (motor). Prevent the following maximum permissible temperature from being exceeded.
+ 40 °C for the environment
The motor is protected against overload by a suitable protective device.
