ways be free of obstructions (no back pressure) to en-
sure an unimpeded discharge of gas. The cross-sec-
tion of the outlet tubing must be at least the size of the
pump’s exhaust connection.
+
Failure to connect the inlet and outlet lines correctly
will cause overpressure and risk of bursting! The outlet
(hose nozzle) is marked ”EX”.
+
Particles and dust must not be aspirated. If necessary,
you must install appropriate filters. You must ensure
their suitability concerning gas flow, chemical resis-
tance and resistance to clogging prior to use.
+
Make sure ventilation is adequate, especially if the pump
is installed in an enclosure, or if the ambient temperature
is elevated. Provide external ventilation, if necessary.
• Reduce the transmission of vibration. Prevent mechan-
ical load due to rigid pipelines. Insert elastic hoses or
flexible elements as couplings between the pump and
rigid pipes.
Note: Flexible elements will compress or flatten when
evacuated if not designed for use under vacuum.
• Hose connections at the pump inlet must always be
gas tight.
• Install a cold trap in front of the pump, if pumping ag-
gressive or corrosive gases or vapors.
• A power failure may cause accidental ventilation of the
pump or the vacuum system, if the manual gas ballast
valve is open. If this constitutes a potential source of
danger, take appropriate safety measures, e.g., install
a solenoid operated gas ballast valve (see “Accesso-
• The pump is supplied dry (i.e., without oil filling) in order
to ensure that oil cannot make its way from the rotary
vane pump into the housing of the oil mist filter. A can
containing 0.5 liter (0.53 quarts) of rotary-pump oil is
supplied with the pump.
