Inlet
☞
If there is a danger of
deposits
in the pump chamber (check inlet and outlet of
the pump) control the pump chamber regularly and clean if necessary.
Connection of the inert gas purge
☞
If the surrounding of the pump is not an explosive atmosphere it is possible to
leave out the inert gas purge.
Connection of the inert gas gas ballast
☞
When using air rather than inert gas, risk of significant damage to equipment and/
or facilities, risk of personal injury or even loss of life exists due to the formation
of hazardous and/or explosive mixtures if air and pumped media react inside or
at the outlet of the pump.
Outlet of the pump
☞
Always connect an exhaust lines at the pump outlet (small flange or hose
nozzle 10 mm).
Perform the outlet line
conductive grounded
and gas tight
(designation of the pump connections see figures). Always connect the exhaust
to a
suitable treatment plant
(e. g. hood).
Overpressure safety valve at the outlet of the pump
The overpressure safety valve
at the outlet prevents reliable high pressures in the
system. Check overpressure safety valve regularly and replace if necessary.
Attention:
Deposits and condensate may lead to increased temperature and
to excess of the max. permitted temperatures! Increased temperatures possibly
may lead to ignition of flammable mixtures inside the pump.
Use inert gas gas ballast if necessary and check pump regularly for deposits.
Install a gas washing bottle, condenser, filter, separator, etc. at the inlet of the
pump if necessary.
Attention: Glass parts (flasks and condensers) of pumping units (pumps
with AK (IK) and EK) have no protection against splinters (against implo
-
sion) or against leakage in case of mechanical damage or hits from outside.
The user must ensure an appropriate protection against splinters / implo-
sion or leakage prior to the first use.
Pumps with two motors
☞
Ensure that in case of pumps with two motors both motors are switched on at the
same time, if not possible switch on the motor of the pump at the outlet first.
☞
Connect the
inert gas connections
at the crankcase not serial but parallel.
