Surfaces under the covers of the SP 250 may attain temperatures over
70 °C.
If during maintenance work the covers are removed, there is the risk of suf-
fering burns.
Therefore always wear the required protective clothing.
With all covers in place there only the remains the risk of suffering burns at
the discharge port.
Do not operate the pump with the covers only partly in place (when disas-
sembling one side, for example) since this will impair the steadiness of the
air flow cooling the pump.
Make sure that the air cooling arrangement is not impaired. When operat-
ing the pump do not leave any items (pieces of cleaning cloth, for example)
on the cooling fins of the pump chamber. Clean the cooling fins when they
are found to be very dirty.
The pump may be damaged if the cooling air flow is restricted..
3.1.3 Ambient Conditions
The pump may be operated under the ambient temperatures specified by the
Technical Data.
At higher ambient temperatures or in the case of a dirty oil cooler, the tem-
perature of the oil can increase to unacceptably high levels. In the case of
high ambient temperatures or in the case of dusty ambient conditions the oil
cooler should be checked more often (see Maintenance).
The pump must be installed such that the side of the discharge flange
remains easily accessible. From this side all maintenance and installation
work can be done.
For installation locations over 3000 m above sea level please consult us.
3.2 Conforming Utilisation
The SP 250 has been developed specifically for the special requirements of
industrial applications.
Typical areas of application are: vacuum furnaces, metallurgical systems,
brazing systems, coating technology, (freeze) drying, packaging, research and
development etc.
The pumps have been designed to pump air or inert gases in the pressure
range between atmospheric pressure and the ultimate pressure of the pump.
If other gases are to be pumped with this pump, please consult Leybold first.
For Part Number 115 003
The inside of the vacuum pump SP 250 ATEX Category 3i in contact with the
process has been specially designed and manufactured to comply with the
safety requirements of Equipment Group II, Category 3 of the “ATEX Directive
(Directive 94/9/EG) on the conforming utilisation of equipment and protection
facilities in explosion hazard areas”.
We recommend connecting the SP-Guard as the monitoring system to the
