General
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.

claims for damages!
11.1
Application Fields
SPECK liquid ring vacuum pumps can be used
for all gases, if the material chosen is
chemically 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.
11.2
Performance Data
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.

Safety
These operating instructions contain basic
information that must be considered at set-up
and during operation and maintenance. For
this reason, the commissioning engineer must
read the operating instructions before
assembly and commissioning. The manual
must also be available to the responsible
personnel/machine user at the pump's place of
operation at all times.
You should not just consider the general safety
information listed in this point, specific safety
information is also contained in the other main
points.

Information located directly on the pump, e.g.
the arrow showing the direction of rotation
the markings of the pipe connections
must always be observed and kept legible.
12.2
Qualification and Training of
Personnel
The operating, maintenance and assembly
personnel must be appropriately qualified for
the work they carry out. The client must
precisely outline the area of responsibility of
the personnel, and monitor their duties.
If the personnel is not suitably qualified, they
