Shutdown:
Short-term:
Has the pump been exposed to condensate?
☞ Allow the pump to continue to run at atmospheric pressure for a few minutes (con-
tinuous pumping at a setting of 60).
Has the pump been exposed to media which may damage the pump materials or forms
deposits?
☞ Check and clean pump heads if necessary.
Has the pressure transducer been exposed to media which may form deposits?
☞ Clean pressure transducer if necessary.
Long-term:
➨ Take measures as described in section short-term shutdown.
➨ Separate pump from the apparatus.
➨ Drain catchpots.
➨ Close inlet and outlet port (e. g. with transport caps).
➨ Store the pump in dry conditions.
Attention: Important notes regarding the use of gas ballast and air
admittance valve
☞ Make sure that air/gas inlet never leads to hazardous, explosive or otherwise dan-
gerous mixtures. If in doubt, use inert gas.
☞ 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.
