3.2 General Information
e 25D-275D types are two-stage liquid ring vacuum
pumps in base plate version.
e motor is connected to the pump sha (3) via a
coupling. e pump sha (3) is mounted in rolling bearings
(4) on both sides. Usually, pump and motor are mounted
onto one base plate. Two maintenance-free mechanical seals
(5) in the sha sealing casings are used to seal the pump
sha (3).

ese pumps allow for the delivery of small volumes of
liquids. e discharged operating liquid can be re-used
when using a separator.
3.3 Design and functional principle
e vacuum pump is operated in accordance with the liquid
ring principle. e impeller is positioned o center in the
cylindrical pump casing. It transfers the drive power to a
liquid ring, which forms concentrically to the casing when
the vacuum pump is started.
255551 (Rev.1) 03/2014 9
Page 10
e gaseous medium remaining in the casing is distributed
around the impeller due to the lower density in the hub
area. As the impeller is positioned o -centre to the casing,
the available space for the gas between the surface of the
liquid and the hub becomes crescent-shaped.
is way, the remaining space for the gas between the
blades expands and shrinks during each rotation.
4 Transport, storage and disposal
e following accident prevention regulations have to
be observed prior to following transport and handling
regulations:

3. Liquid ring
Fig. 5 Functional principle of liquid ring vacuum pumps
e arrangement of suction and pressure openings in
the inter casing allows for the suction, compression and
discharge of gas. e liquid both serves the sealing between
the individual impeller chambers and the absorption of heat
produced during compression.
e vacuum pump must be permanently supplied with
operating liquid during operation as a portion of the liquid
continuously escapes from the pump together with the gas.
e discharged operating liquid can be separated from the
gas by means of a downstream separator and re-used.
