Installation and connection
4.4 Connection
The diaphragm pumps have a vacuum connection and an outlet
connection. Connect your diaphragm pump as described in the
examples below.
4.4.1 Assemble silencer (EX)
As standard the diaphragm pumps are equipped with a silencer at
the outlet (EX). The silencer is separately packed.
WARNING
Risk of bursting due to internal overpressure at the
silencer.
Inadmissibly high pressure at the silencer can cause the
vacuum pump to burst or damage the pump bearings,
diaphragms and valves.
Internal overpressure may build up in case of high
gas flow rate or in case of deposits inside the silencer
caused by pumping gases containing dust or solvent
vapors.
> >
Do not p ump any substances which could form de ‑
posits inside the silencer.
> >
In case of permanently high gas flow or if there is a
risk of deposits replace the silencer at the outlet by
a small flange connection or a hose nozzle and con‑
nect an outlet line, see 4.4.3 Outlet connection (EX)
on page 32.
