1. Description,
Operating Conditions
The pump transfer, and evacuate
100 % oil-free.
1.1 Electrical Equipment
– See section 9 for full electrical data.
– The protection class of standard ver-
sions is IP 44.
– The pumps are fitted with a thermal
– switch to protect against over-
loading.
1.2 Operating Conditions
– Handling air, gases, and vapours
at temperatures between
+ 5°C ... + 40°C.
– For maximum permissible operating
pressure, ultimate vacuum, and flow
capacity: see chapter 9.
!
The pumps must not be used in areas
where there is a danger of explosion.
– Before pumping a medium, the
compatibility of materials of pump
head, diaphragm and valves with the
medium must be checked
(for pump materials: see chapter 9).
– The pumps must not be used for
liquids. You will find suitable liquid
pumps in our product programme.
If your potential application lies out-
side the above limits discuss it with
our technical adviser (see last page
for contact telephon number).
1.3 Ambient Condition
When the pumps are operating the
following ambient conditions must
be maintained:
– Ambient temperature during
operation: between + 5°C ... + 40°C.
– During operation an adequate
supply of air for cooling must be
provided.
– The pumps must not be used in areas
where there is a danger of explosion.
1.4 Pump materials
See chapter 9.

Safety

– Note that the pumps may only be
used for their intended purpose
(see section 1).
!
The pumps must not be used in areas
where there is a danger of explosion.
– The discharge of gas on the
pressure side of the pump must
be safely disposed.
Components connected to the
!
pumps must be designed to with-
stand the pneumatic performance of
the pumps (see chapter 9).
– Plug the pump only into properly
installed grounded outlets.
When the operation of the pump
!
is interrupted by the thermal switch,
it will re-start automatically after
cooling down. Take all care neces-
sary to prevent this leading
to a dangerous situation.
Specific safety instructions and
!
measures for the media being
handled must be observed.
– Parts of the casing marked with the
sign below are only allowed to be
opened after pulling out the plug
(disconnecting the power source).
– Use only original Sartorius replace-
ment parts.
• The pumps correspond to IEC 664:
– the overvoltage category II
– the pollution degree

Installation

– Choose a safe location (flat surface)
for the pump.
– Install the pump so as to ensure
adequate flow of air cooling.
– Fit the pump at the highest point
in the system, so that condensate
cannot collect in the head of the
pump – that prolongs working life.
– Connect the suction and pressure
lines (tube ID 9). For flow direction
see marking on the pump head.
– Arrange the suction and pressure
lines so that condensate cannot
run into the pump (sloping lines).
– Plug the pump only into properly
installed grounded outlets.
– Compare the supply data with the
elecetrical data of the pump. The
voltage must not vary by more than
+6%, and –10% from that shown on
the type-plate.
