1. Introduction
To prevent contamination from possible dangerous substances contained in the process, the exhaust outlet must always be
connected to an appropriate emission control system.
All units being returned to our works for maintenance or any other reason must be free of harmful and dangerous
material. A Health and Safety certificate should always be provided.
The customer has the responsibility for providing and checking explosion proof safety requirements for the total site in which
vacuum pumps are used.
An appropriate agreement should be obtained from the local licensing authorities.
2. Application
The TWISTER vacuum pumps are particularly suitable for the handling of extremely humid gases. These pumps have a high water
vapour tolerance.
The ambient temperatures may be between 5 and 40°C. The suction temperatures should not exceed 60°C. For
temperatures out of this range please contact your supplier.
Liquid slugs and solids cannot be handled by TWISTER.
Handling of explosive gases or vapours only on request with our company.
For installations that are higher than 1000 m sea level there will be a loss in capacity. For further advice please
contact your supplier.
The standard versions may not be used in hazardous areas. Special versions with Ex-proof motors can be supplied.
All applications where an unplanned shut down of the pump could possibly cause harm to persons or installa-
tions, then the corresponding safety backup systems must be installed.
