3.2 Additional protection measures against liquids in the pump
3.2.1 Condensate separator (Suction side)
To prevent accidental ingress of liquids (condensate) in the pump, a plastic separator with
ball check valve is mounted on the suction side regulator.
If the possibility of penetration of larger liquid quantities which exceed the capacity of the
plastic separator, we recommend the additional installation of a larger collection vessel
(eg. Woulff bottle).
3.2.2 Cold trap (Suction side)
The installation of an appropriate cold trap is required when a larger amount of steam (water,
solvent) is obtained which exceeds the tolerance of the vapor pump.
The refrigerant used is usually dry ice or dry ice mixture with an acetone or alcohol.
Maintenance:
The refrigerant must have the highest possible level in the cold trap.
The rise in pressure in the connected vacuum apparatus indicates that the cold trap is satu-
rated.
For cleaning remove the cold trap and defrost. The condensate must be disposed of prop-
erly. The cool trap is, if applicable, clean with a detergent and dry.
3.3 Areas of Application
The WOB-L®Piston Pumps are intended to:
Pumping and compressing neutral and aggressive gases and vapours.
Generating a vacuum down to a minimum ultimate pressure < 6.7 mbar.
