pump
models
with
the
following main characteristics:
- A
direct
drive
motor,
making
them
very compact.
-An electrically insulated fold-away
handle
is
used for easy carrying.
-An
anti-suckback
system
ensures
the tightness of the pump during
accidental or voluntary shutdowns.
- A
gas
ballast
enables the pumping
of condensable vapours (except for
C2
series).
-
The
universal three-phase or single-
phase
motor
can be disassembled
independently
of the
rest
of the
pump, without the need to drain
the
oil case.
-
On
the oil case, a
vertical
sight
glass
can be
used
to
inspect
the
oil
level easily when filling
the
tank and
during the operation of
the
pump.
- A
neutral
gas
purge
is
used
to
degas oil and dilute pumped gases
on
C2
series models.

The
inlet and exhaust end fittings are
PNEUROP
ISO-KF
standardized.
They are fitted vertically on the pump at delivery but can be positioned on
the horizontal openings
if
required
by
operating conditions.
They can also be
used
to connect many of our accessories
(see
page
63).
The
main remplacement parts are interchangeable:
This
enables easier
disassembly-assembly operations and replacement without changing the
pump's performance.
Various accessories can be
used
to
adapt
the
pump to meet the requirements
of your application.
The
moulded aluminium pump frame supports the pumping module and
the
motor. All the parts of the pumping module
in
contact with gases are free of
zinc, copper and cadmium.
The
other construction materials include cast iron, aluminium alloy, stainless
steel, fluorocarbons
(FPM),
nitril
(NBR)
and chemically resistant polymers.
