Inlet and exhaust fitting
For a given application, pump performance, vacuum characteristics,
temperature and reliability depend on the following:
- assembly conditions, accessory filters.
- the oil used.
- mechanical connections: pipes, etc.
- maintenance frequency and quality.
For the assembly of the vacuum circuit, provide the accessories required for
maintenance: valves, purges, etc.
The pump can be mounted on a frame using the 4 attachment holes on the base
and the shock mounts supplied.
Note: Special shock mounts, effective against the pump's own vibrations, can also
be used but they do not ensure correct attachment during the transfer of equipment.
In this case, the pump should be clamped onto its support.
The pump and the motor are each equipped with a ventilation system. During pump
installation, the pump should be placed in ventilated place. Provide a minimum gap
of 25 mm around the pump.
The vents on the pump and the motor should be checked regularly to ensure that
they are not blocked.
Pascal Series ALCATEL pumps are designed for operation at an ambient temperature
between 53°F and 113°F (12 and 45°C).
Remove the protective caps on the inlet and exhaust orifices; these
components prevent foreign bodies from entering the pump during transport
and storage. It is dangerous to leave them on the pump during operation.
The pump inlet and exhaust orifices are equipped with DN 25 ISO-KF end fittings
which can be used to fit various line components made of stainless steel, plastic,
etc. (see Alcatel catalog).
Exhaust
It is recommended to connect the
pump exhaust to a smoke
evacuation duct.
• If the pump exhaust orifice is
connected to an extraction duct or an
oil mist eliminator, the exhaust stop
valve fitted in the pump exhaust orifice
must be removed.
• At the pump exhaust, the evacuation
circuit must be such that the resulting
excess pressure in the oil case is as low
as possible: for correct pump operation
the max. exhaust pressure recommended
should be 1,125 Torr (1.5 bar) absolute
pressure.
Inlet
Make sure that all the components
or chamber connected to the
pump inlet withstand a negative pressure
of 1 bar relative to atmospheric pressure.
Also make sure that the maximum
excess pressure does not exceed
1 bar relative to atmospheric pressure
(for security).
