OPERATING INSTRUCTIONS
General
1
The descriptions and instructions in these
operating instructions refer to the standard
pump versions. These operating instructions
do not cover all possible design details nor
variants. Any illustrations and informations in
these instructions are subject to technical
modifications.
Note: The opening of the pump, invalidates all
claims for damages!
Application Fields
1.1
SPECK liquid ring vacuum pumps can be used
for all gases, if the material chosen is chemi-
cally resistant both against the gas and the
ring liquid. Up to 33 mbar the pumps are
working economically with water as ring liquid
at an inlet temperature of 15 °C. At different
operating liquids the characteristic curves
change (e.g. different physical data of the gas
or the operating liquid , or any other liquid
added additionally, delivery of gas-steam
mixtures).
Service value limits see chapter 10.
Performance Data
1.2
Besides the operating data, the name plate of
the pump shows the pump type, pump size
and pump number, which have to be specified
for any queries, supplementary orders and
especially for spare-part orders.
If you have any queries, please contact your
supplier or the manufacturer.
