➨
Vent and dispose of
potentially dangerous gases or
vapors at the outlet of the pump appropriately.
+
Due to the high compression ratio, the pump might
generate overpressure at the outlet. Check pressure
compatibility with system components (e.g., exhaust
tubing or exhaust valve) at the outlet. Ensure that the
pump outlet is neither blocked nor restricted.

Operation with silencer at the outlet: Oper-
ating the pump at a high inlet pressure or
pumping dusty gases for a long time may
cause clogging of the silencer. Check the
silencer regularly and replace if necessary,
or install a hose nozzle with sealing ring in-
stead (see “Accessories”, pg. 51).
