2. Never remove the oil-ll or oil-drain plugs when the pump is in operaon. There
exists the risk of suering burns. Always wear protecve gloves and protecve
goggles also for protecon against the oil.
2.4 Hazards caused by materials and substances
1. The pump is not designed for:
▪ pumping of dusty, aggressive, corrosive, ammable or explosive gases or gases
mixtures
▪ pumping of oxygen or other highly reacve gases with a greater concentraon
than the atmospheric concentraon (> 20%)
▪ working in a ammable or explosive environment.
For all these cases, special materials must be used. In case of doubt, contact
us.
Also, see the limits of use indicated in the CE declaraon of conformity.
2. Depending on the process involved, dangerous substances and oil may escape
from the pump. Follow the necessary safety precauons.
3. Take appropriate precauons to make sure that the pump cannot start.
4. If the pump has pumped hazardous gases it will be necessary to determine the
nature of the hazard involved and take the appropriate safety precauons.
5. Take adequate safety precauons before you open the intake or exhaust port.
6. Follow the instrucons for environment protecon when you dispose of the used
oil or exhaust lters.
7. Some pumps use peruoropolyether (PFPE) as a lubricant. When handling (PFPE)
you should observe the following: During thermal decomposion at temperatures
over 290 °C toxic and corrosive gases are released. When handling PFPE keep it
away from open res. Do not smoke with PFPE on your ngers.
8. Touch the inner secons of the pumps only while wearing clean gloves and use a
clean tool. Do the necessary work in clean and dry rooms.
2.5 Danger of pump damage
1. There is a risk of severe damage if any object falls in the pump. Make sure that no
objects (screws, welding beads, nuts, washers, pieces of wire, ngs etc.) enter
through the intake port of the pump.
2. Make sure that liquid and solid parcles do not enter the pump. Install adequate
lters, separators and/or condensers. In case of doubt contact us.
3. Do not connect the intake line of the pump to a device with over atmospheric
pressure. The exhaust line must be designed so that the pressure will not exceed
1.1 bar absolute (0.1 bar relave).
4. Make sure that the pump exhaust is not closed or restricted.
5. The pump is designed for indoor use only and must be operated below 2000 m sea
level.
6. If you operate the pump without oil or with incorrect rotaon direcon for a long
me, it can destroy the pump and create dangerous situaons.
7. Never use discarded seals. Always use new seals for assembly.
