Preface
Dear customer,
your new Liquid Ring Pump is the outcome of intensive
development based on decades of experience as a
supplier of vacuum pumps and compressors to the
suction vehicle market. Advanced manufacturing
methods in combination with highest quality standards
and extensive testing ensure reliability, a high degree
of availability and long life of your machine.
You will appreciate that this machine requires expert
attention, especially in severe conditions. Commis-
sioning, operation and maintenance therefore require
trained and authorized personnel.
These Operating Instructions contain all required infor-
mation and have been written for those in charge of the
unit. The machine will give smooth service for a long
time provided these Instructions are followed. The Op-
erating Instructions are a component part of the prod-
uct and must be kept available for the operating
personnel. You will appreciate that we cannot be held
responsible for any damage caused due to non-com-
pliance with these Instructions.
Please note that repairs should only be undertaken by
authorized repair centres using original parts. Other-
wise our guarantee will be void.
We wish you success with your Liquid ring pump from
Gardner Denver. If you have any questions for which
you do not find an answer in this booklet, please call
us.
Sincerely yours,
Gardner Denver Drum

Mode of operation
Liquid compressor vacuum pumps, like rotary com-
pressor vacuum pumps, work on the displacement
principle, providing uniform, low-pulsation flow.
Single-shaft liquid ring machines have a housing with
cylindrical bore and an eccentrically mounted bucket
wheel. The housing is partly filled with liquid, which the
rotation of the bucket wheel forms into a rotating liquid
ring in contact with the housing. Together with the hub
of the eccentrically mounted bucket wheel, it forms a
sickle-shape working space divided by the vanes of
the bucket wheel.
The rotation of the rotor causes the cell volume to be-
come large at the intake side. This causes a vacuum
which sucks air into the cell, which is open towards the
air intake. As the rotation continues, the cell closes and
the cell volume becomes smaller. As a result of this,
the enclosed air is compressed and pushed out of the
pressure outlet.
The cells are charged and drained through openings in
the housing cover located on the bucket wheel faces.
This functional principle causes the machine to work
nearly at isothermal compression due to internal cool-
ing.
The first digit of the references to illustrations
in these Operating Instructions refers to the
chapter in which you find the illustration. The
illustrations within each chapter are numbered
consecutively. The last number of an illustra-
tion reference denotes the position number of
the item in the references illustration.
For example, the reference (7.2 / 3):
second illustration in chapter 7, item number 3.
This symbol precedes information that refers to
units used in a potentially explosive atmos-
phere.

The design versions differ in their sense of rotation.
