The manufacturer does not accept liability for damage
resulting from non-observance of the overall documenta-
tion.
2.1 Intended use
•Observe all provisions included in the operating manual.
•Observe all safety instructions.
•Comply with inspection and maintenance intervals.
•Use the vacuum unit exclusively for delivery of the permis-
sible media to be pumped
(General technical data, page 25).
•Operate the vacuum unit with permissible operating liquid
only (General technical data, page 25).
•Prevent dry running:
Ensure that the vacuum unit is only operated with suf-
ficient operating liquid, never without operating liquid.
•Prevent cavitation:
Comply with the temperature limits of the operating liq-
uid and the medium to be pumped.
Observe the limit values for inlet pressure and pres-
sure difference.
Do not operate the aggregate when the fitting in the
suction pipe is closed.
•Prevent overheating:
Do not operate the vacuum unit when the fittings are
closed.
•Prevent motor damage:
Observe the maximum flow rate for delivery of liquids.
Observe the switching frequency of the aggregate.

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 vacuum unit concerning
temperature, pressure, speed, density and viscosity
(Operating limits, page 25).
•The 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 con-
tent limit values (General technical data, page 25).
•Do not combine multiple limit values
(Operating limits, page 25).
•Prevent sudden pressure changes of the gas to be extract-
ed.
•Prevent sudden temperature changes of the gas to be
extracted or the operating liquid.

3.2 General description
BluVacCompact vacuum units produce a demand-matched
vacuum while simultaneously delivering large amounts of liquid.
The integrated separator (1) allows for the separation of the
drawn-in air-water-mixture. The default vacuum or the filling level
in the separator is regulated by means of a type VI (2) frequen-
cy-controlled liquid ring vacuum pump combined with a dis-
charge pump.

Fig. 2 Description BluVacCompact vacuum unit

Operating Manual
11/2017 1096.0233 | BluVacCompact Vacuum Units 9
The vacuum unit is controlled by the BluSystems control panel
(3), which also allows various system statuses and process
variables to be displayed. The optional alarm light (4) displays
malfunctions.
The pressure sensor (5) continuously records the pressure level
in the tank. Based on these measuring data, the frequency
converter (6) automatically regulates the pressure level by
adapting the motor frequency. The filling level in the tank is
regulated by the special hydraulic design of the discharge pump
without sensors. The optional valve (7) is to switch the fresh
liquid needed by the vacuum pump on or off.
The BluVacCompact vacuum unit is available in three different
designs for fresh water supply:
•With solenoid valve
•With electro-pneumatic angle seat valve
•Self-priming/no valve
The demand-matched generation of vacuum by BluVacCompact
vacuum units results in considerable power savings for
processes without leakage air addition.
3.2.1 Software versions
For vacuum units with FCP 106 frequency converter the follow-
ing software versions apply:
•With usage of a BluSystems operating panel:
BluSystems operating panel software version ≥ 4.00
•With usage pf a PLC controller:
BluSystems-PLC software ≥ 3.00

3.3.2 Liquid ring vacuum pump
The vacuum pump VI is operated in accordance with the liquid
ring principle. The impeller is positioned off-centre in the cylindri-
cal pump casing. It transfers the drive power to a liquid ring,
which forms concentrically to the casing when the vacuum pump
is started.
The 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 off-centre to the casing, the available
space for the gas between the surface of the liquid and the hub
becomes crescent-shaped.
This way, the remaining space for the gas between the vanes
expands and shrinks during each rotation.
1 Suction opening
2 Pressure opening
3 Liquid ring
Fig. 4 Functional principle of liquid ring vacuum pumps
The arrangement of suction and pressure openings in the inter
casing allows for the suction, compression and discharge of gas.
The liquid both serves the sealing between the individual impel-
ler chambers and the absorption of heat produced during com-
pression.
The vacuum pump must be permanently supplied with fresh
liquid during operation as some portion of the liquid continuously
escapes from the pump together with the gas. The discharged
operating liquid is purged from the pressure connection of the
vacuum pump.
3.4 Shaft sealings
3.4.1 Shaft sealings
Mechanical seals may slightly leak for functional reasons.
•Single mechanical seals, unbalanced, dependent on the
direction of rotation, EN 12756 (standard).
The mechanical seal of the vacuum pump is contained in a
mechanical seal casing.
