Preventing foreign bodies inside the pump
Observing the vac-
uum pump design
Particles, liquids and dust are not permitted inside the vacuum
pump.
ð Do not pump any substances that can form deposits inside the
vacuum pump.
ð Install suitable separators and/or filters in front of the inlet.
Suitable filters are chemical resistant, clog-free and ensure a
constant flow rate.
ð
Replace porous vacuum hoses promptly.
2.7 Possible sources of danger
Considering mechanical stability
Observing mechani-
cal stability
Due to the high compression ratio of the pumps, a higher pressure
can build up at the outlet than the mechanical stability of the sys-
tem allows.
ð
Always ensure that the exhaust line is open and free of pres-
sure. To guarantee an unobstructed emission of gases, the out-
let must remain unblocked.
ð Prevent uncontrolled excess pressure, e.g. due to shut-off or
blocked piping system, condensate or clogged exhaust line.
ð At the gas connections, the connections for inlet (IN) and outlet
(EX) must never be confused.
ð Observe the max. pressure at the inlet and outlet of the pump
as well as the max. permissible differential pressure between
inlet and outlet, in accordance with the technical data.
ð
The system to be evacuated and all hose connections must be
mechanically stable.
ð
Attach the coolant hoses to the hose nozzles so that they do not
come loose unintentionally.
