2 Safety
e manufacturer does not accept liability for
damage resulting from non-observance of the overall
documentation.
2.1 Intended use
• Observe all provisions included in the operating
instructions.
• Observe all safety instructions.
• Comply with inspection and maintenance intervals.
• Use the aggregate exclusively for delivery of the
permissible media to be pumped (→ General technical
data, page 28).
• Operate the aggregate with permissible operating liquid
only (→ General technical data, page 28).
• Observe the operating limits (→ Operating limits, page
28).
• Prevent dry running:
− e sealing rings of the mechanical seals will be
damaged within only few seconds.
− Ensure that the aggregate is only operated with
sucient operating liquid, never without operating
liquid.
• Prevent cavitation:
− Install a vacuum check valve.
− Comply with the temperature limits of the operating
liquid and the medium to be pumped.
− Observe the limit values for inlet pressure and
pressure dierence.
− Do not operate the pump when the tting in the
suction pipe is closed.
• Prevent overheating:
− Do not operate the aggregate when ttings are closed.
• Prevent motor damage:
− Observe the maximum ow rate for delivery of
liquids.
− Observe the switching frequency of the aggregate.
− e motor protection switch must not be set to a
value above nominal current.
• Any use other than the intended use must be agreed
with the manufacturer.
2.2 Potential misuse
• Observe the operating limits of the aggregate
concerning temperature, pressure, speed, density and
viscosity (→ Operating limits, page 28).
• e higher the density of the operating liquid, the
higher the motor power consumption. Observe the
permissible density to protect the aggregate against
overload.
• When delivering solid laden liquids, observe the solid
content limit values (→ General technical data, page 28).
• Do not combine multiple limit values (→ Operating
limits, page 28).
• Prevent sudden pressure changes of the gas to be
extracted.
• Prevent sudden temperature changes of the gas to be
extracted or operating liquid.
• Do not use in rooms where explosive gases may
be present unless the aggregate has been expressly
intended for such purpose.
• Do not extract, deliver or compact explosive,
inammable, aggressive or toxic media unless the
aggregates have been expressly intended for such
purpose.
• Unauthorized opening of the aggregate results in the
forfeiture of any and all claims for defects.

3.2 General description
e pumps of the SM series are horizontal, single-stage
liquid ring vacuum pumps with radial inlet and outlet.
e internal control of the gas to be pumped is realized by
means of inter casings (1) with control slots and additional
valve technology (2).
e electrical drive is modularly screwed to the pump
(aggregate). A maintenance-free mechanical seal (4) in the
sha sealing casing is used to seal the sha.
e aggregates of the SM series are able to deliver low liquid
ow rates. e discharged operating liquid can be re-used
when using a separator.

10 255548 Rev.1
3.3 Design and functional principle
e 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 pump is started.
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-center 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.
1. Suction opening
2. Pressure opening
3. Liquid ring
Fig. 4 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 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.
3.4 Sha sealing
3.4.1 Mechanical seal
Mechanical seals may slightly leak for functional reasons.
• Single mechanical seal, unbalanced, dependent on the
direction of rotation with conical spring
