Connecting the outlet
Outlet via silencer respectively via hose noz-
zle for tubing I.D. 3/8” (10 mm) (MD 4S NT) or
small flange KF DN 16 (MD 4CRL NT).
Attention
: Use the silencer only in case of low
gas throughput. Check the silencer regularly
for permeability! In case, install a hose nozzle
with sealing ring instead (see “Accessories”,
Connecting an exhaust line at the outlet of a
pump with silencer at the outlet:
Unscrew the silencer and install a hose nozzle
DN 10 mm with sealing ring (thread G1/4”).
NOTICE
outlet
➨
If dangerous or polluting fluids could be released at
the outlet, install an appropriate system to catch and
dispose of those fluids.
+
Connect a gas-tight exhaust line at the pump
outlet nozzle and secure against loosen-
ing, for example, with a hose clamp. Always
vent exhaust gases appropriately (e.g., into
a fume hood).In case, replace silencer with
hose nozzle, see above).
+
MD 4CRL NT: Connect a gas-tight exhaust
line at the pump outlet (small flange KF DN
16).
+
Never block the gas outlet. The exhaust
line must always be free of obstructions (no
back pressure) to ensure an unimpeded
discharge of gas. The cross-section of the
outlet tubing must be at least the size of the
pump’s exhaust connection.
