Versions
Two versions of the S
ECO
rotary vane vacuum pumps are available :
u
Model SV
For vacuum applications down to an ultimate pressure of 100
hPa.
u
Model SD
For overpressure duties up to 1500 hPa (2500 hPa abs.).
Cooling
The vacuum pump is cooled by
–
the ambient air around the vacuum pump
–
the air flow from the drive motor fan
–
an air cooling coil
Operationnal Options/ Use of
Optionally Available Equipment
–
Air filter to be fitted in series to the integral inlet filter when air
with a higher content of dust is being drawn.
–
Vacuum relief valve to control inlet pressure when pump is used on
vacuum duties (SV series only).
–
Pressure relief valve to control pressure when pump is used on
overpressure duties (SD series only).
–
A non-return valve, fitted to either the suction or the discharge
line, protects the system against ingress of air or depressurization,
should the pump stop for any reason. The installation of non-re-
turn valves is recommended if lines of more than 5 meters are
used.
On/ Off switch
This vacuum pump comes without an on/off switch. The control of the
vacuum pump has to be provided for in the course of installation.
Safety
Intended use
DEFINITION
: For the purpose of these instructions, “handling” the va-
cuum pump means the transport, storage, installation, commissioning,
influence on operating conditions, maintenance, troubleshooting and
overhaul of the vacuum pump.
The vacuum pump is intended for industrial use. It should only be han-
dled by qualified personnel.
The different application of the pump and operational limits according
to the “Product Description” and the “Installation Prerequisites” of
the vacuum pump must be observed both by the manufacturer of the
machinery into which the vacuum pump is to be incorporated, and by
the operator.
The maintenance instructions must be adhered to.
Prior to handling the vacuum pump, these operating instructions must
be read and understood. If anything remains to be clarified, please
contact your Busch representative!
Safety notes
This vacuum pump has been designed and manufactured in accor-
dance with the latest technical standards, and with current safety
requirements. Nevertheless, residual risks may remain. These operating
instructions inform about potential hazards where appropriate. Safety
notes are tagged with one of the keywords DANGER, WARNING and
CAUTION as follows:
DANGER
Disregard of this safety note will always lead to accidents with fa-
tal or serious injuries.
WARNING
Disregard of this safety note may lead to accidents with fatal or se-
rious injuries.
CAUTION
Disregard of this safety note may lead to accidents with minor inju-
ries or property damage.
Sound Emissions
For the sound pressure level in free field operation according to EN ISO
2151, please see “Technical Data”.
CAUTION
The vacuum pump emits noise of medium intensity.
Risk of damage to hearing.
People staying in the vicinity of a non-noise insulated vacuum pump
over extended periods sof time must wear suitable ear protection.
Transport
CAUTION
Please check the weight of the vacuum pump before lifting it up
(see "Technical Data")
Use adequate lifting gear for this.
Seco vacuum pumps pass a rigorous operating test in the factory and
are packed carefully to avoid transit damage.
The suction and the discharge apertures are sealed with plugs so that
no dirt can enter the pump during transport. These protections must be
removed before connecting the vacuum pump.
Please check packaging on delivery for any transport damage.
The pump can be lifted from its packaging with a suitable lifting device
using the lifting bracket on the pump.
Packing materials should be disposed of according to environmental
laws, or reused.
CAUTION
Do not walk, work or stand under suspended loads.
Storage
Short-term Storage
l
Make sure that the suction connection/gas inlet and the gas dis-
charge/pressure connection are closed (refit the plugs the pump
was delivered with)
l
Store the vacuum pump
–
if possible in its original packaging,
–
indoors,
–
dry,
–
dust free
–
vibration free
