Small quantities of light suspended matter
or liquids can be conveyed along too.
 are designed for operation with the following
operating-liquids:
- Water
of pH-value between 6 and 9,
that are free of solid matter (e.g. sand).
- in the case of pH-values or operating-liquids
deviating from the above, please contact
the manufacturer.
 are suitable for a deep vacuum range.
 are fitted with one of the following types of

These operating instructions are only applica-
ble for units in the standard design.
For the explosion-protected design
(RL 94/9/EG) - see supplementary special
operating instructions.
 are available in two constructions:
- cast iron construction for normal require-
ments,
- stainless steel construction for higher corro-

 to operate the unit in spaces in which explo-
sive gases may be present, insofar as the unit
is not specifically designed for such condi-
tions;
 extraction, conveyance and compression
of explosives, combustible, aggressive or poi-
sonous media,
insofar as the unit is not specifically designed
for such conditions,
 operation of the unit at any values other than
those specified in chapter 3, "Technical data",
page 8 hereunder.
